Description: This invention relates to additive concentrates and oleaginous compositions (i.e., lubricating oils and functional fluids) having enhanced performance properties. Heretofore a number of additive concentrates containing, inter alia, sulfur-containing antiwear and/or extreme pressure additives, phosphorus-containing antiwear and/or extreme pressure additives, and other additive components have been proposed and used. Among such other additive components are acidic components such as carboxylic acids, hydrocarbyl phosphoric acids, and hydrocarbyl thiophosphoric acids; basic components such as amines; and ashless dispersants such as boronated succinimides. In order to qualify for premium automotive gear oil usage, the finished lubricating oil composition and additive concentrate from which it is made must be formulated to meet the American Petroleum Institute GL-5 requirements. This involves passing a battery of standard tests. In addition, the provision of clean gears in the L-60 test is an important consideration in the marketplace. So far as is known, only a very limited number of lubricant additive packages have received GL-5 approval. Thus there is a need for additional automotive gear oil packages which give good performance in the GL-5 qualification tests, and especially for packages capable of satisfying the GL-5 requirements. There is, additionally, a need for automotive gear oil formulations which not only meet the GL-5 requirements but which afford superior results in the standard planetary spur gear test. Still another need is for an ashless or low-ash lubricant additive package affording high dispersancy and high wear resistance to lubricants, such as crankcase lubricants, gear lubricants, manual and automatic transmission fluids, oil-based hydraulic fluids, wet brake fluids, and similar lubricants and functional fluids. Yet another need is for an automotive or industrial gear oil package which performs well in synthetic base oils. In accordance with one embodiment of this invention, there is provided an additive concentrate which comprises a minor proportion of diluent oil and a major proportion of additive components, said additive components comprising: a-1) at least one oil-soluble additive composition formed by heating concurrently or in any sequence at least one ashless dispersant which contains basic nitrogen and/or at least one hydroxyl group with (i) at least one inorganic phosphorus acid or anhydride, or at least one partial or total sulfur analog thereof, or any combination of the foregoing, and (ii) at least one boron compound; such that a liquid composition is formed; or a-2) at least one oil-soluble boron-free additive composition formed by heating (i) at least one boron-free oil-soluble ashless dispersant containing basic nitrogen and/or at least one hydroxyl group, with (ii) at least one inorganic phosphorus acid such that a liquid boron-free phosphorus-containing composition is formed; or a-3) one or more oil-soluble additive compositions formed by heating concurrently or in any sequence at least one ashless dispersant which contains basic nitrogen and/or at least one hydroxyl group with (i) at least one water-hydrolyzable organic phosphorus compound and water; and (ii) at least one boron compound; such that a liquid phosphorus- and boron-containing composition is formed; or a-4) one or more oil-soluble boron-free additive compositions formed by heating concurrently or in any sequence (i) at least one boron-free oil-soluble ashless dispersant which contains basic nitrogen and/or at least one hydroxyl group, with (ii) -at least one water-hydrolyzable organic phosphorus compound and water, such that a liquid boron-free phosphorus-containing composition is formed; and b) at least one oil-soluble metal-free sulfur-containing antiwear and/or extreme pressure agent having a sulfur content of at least 20% by weight The term "component a)" as used hereinafter refers collectively to the above components a-1), a-2), a-3) and a-4). The cooperation between components a) and b) of such compositions makes it possible to achieve performance levels (reduction in sludge formation and/or deposition and reduction in wear in gears and/or other relatively moveable metal surfaces in contact with each other) normally achieved, if at all, by higher concentrations of component b). More particularly, the cooperation between components a) and b) can provide these important performance-improving effects: 1) inhibition of scoring or scuffing such as results from micro-welding of asperities between relatively moving metallic mechanical energy transferring surfaces in close proximity to each other, particularly under conditions of high speed and shock; 2) inhibition of ridging and rippling such as results from metal deformation or surface flow of relatively moving metallic surfaces in close proximity to each other, particularly under conditions of low speed and high torque; 3) inhibition of pitting and spalling such as results from metal fatigue in relatively moving metallic surfaces in close proximity to each other, particularly under conditions of low speed and high torque; and 4) inhibition of sludge and varnish formation in base oils and/or deposition of sludge and/or varnish on both stationary and relatively moving parts of engines, hydraulic systems, gear boxes, power transmissions or like mechanisms, especially when operated under high temperature conditions. Thus, the additive combinations of this invention have the capability of contributing greatly improved performance properties to base oils of lubricating viscosity, including animal, vegetable, mineral, and synthetic oils. For example, significantly improved properties can be achieved in lubricant compositions of this invention when subjected to various API GL-5 test procedures, such as enhanced extreme pressure properties as seen in the standard L-42 test, improved antirust performance as seen in the standard L-33 test, and/or clean gears as seen in the standard L-60 test Indeed, particularly preferred compositions of this invention are those which satisfy all of the requirements of the API GL-5 test procedures. In addition, particularly preferred compositions of this invention exhibit superior performance in the standard planetary spur gear test. In order to achieve optimum beneficial performance effects such as those referred to above, components a) and b) are proportioned such that the mass ratio (wt:wt) of sulfur in component b) to phosphorus in component a) is in the range of 8:1 to 30:1, more preferably in the range of 10:1 to 20:1, and most preferably in the range of 14:1 to 20:1. The finished lubricating oils of this invention will usually contain at least about 05 wt % of sulfur as component b) and preferably will contain an amount of component b) to provide a sulfur content in the finished lubricant in the range of 1 to 3 wt %, and more preferably in the range of 1.5 to 3 wt %, of the total weight of the composition. In preferred embodiments, the foregoing additive concentrates further comprise one or more of the following additive components: c) at least one oil-soluble amine salt of a mono- or dihydrocarbyl ester of a monomeric pentavalent acid of phosphorus, preferably wherein the acid is phosphoric acid or a monothiophosphoric acid; and/or d) at least one oil-soluble trihydrocarbyl ester of a dithiophosphoric acid; and/or e) at least one oil-soluble amine salt of a carboxylic acid; and/or f) at least one oil-soluble demulsifying agent; and/or g) at least one oil-soluble copper corrosion inhibitor. When component a-2) or a-4) is used, the following additive component can also be used in preferred embodiments: h) at least one oil-soluble or oil-dispersible boron-containing additve composition. Also provided by this invention are lubricant compositions which comprise a major proportion of at least one oil of lubricating viscosity and a minor amount of the various additive combinations referred to hereinabove. Preferably, the compositions of this invention are ashless compositions (i.e., they contain no metal-containing additive components) or are low-ash compositions (i.e., base oil containing an additive concentrate or a combination of additives pursuant to this invention at a total concentration of 10% by weight will contain no more than 100 parts by weight, and more preferably no more than 50 parts by weight, of added metal per million parts by weight of the total composition. Component a) -- i.e., a-1), a-2), a-3) or a-4) -- is one indispensable additive ingredient of the compositions of this invention. Component a-1) - Phosphorylated & Boronated Ashless Dispersant The ashless dispersant which is heated concurrently or in any sequence with components (i) and (ii) is preferably a preformed ashless dispersant containing basic nitrogen and/or at least one hydroxyl group. Thus, for example, any suitable ashless dispersant formed in the customary manner can be heated with one or more boron compounds to cause boronation to occur and the resultant product mixture can then be heated with one or more inorganic phosphorus compounds such that a liquid phosphorus- and boron-containing composition [component a-1)] is formed. Conversely, a preformed ashless dispersant can be heated with one or more inorganic phosphorus compounds and thereafter the product mixture can be heated with one or more boron compounds so that a liquid phosphorus- and boron-containing composition is formed. The preferred way of forming component a-1) is to heat a preformed ashless dispersant with a combination of one or more inorganic phosphorus compounds and one or more boron compounds to form a liquid phosphorus- and boron-containing composition. In other words, to form component a-1) in the preferred manner, the preformed ashless dispersant is concurrently heated with one or more inorganic phosphorus compounds and one or more boron compounds. In all cases, the resulting liquid product composition when subjected to chemical analysis reveals the presence of both phosphorus and boron. Rather than utilizing a preformed ashless dispersant containing basic nitrogen and/or at least one hydroxyl group, it is possible to produce component a-1) by: 1) forming the ashless dispersant in the presence of one or more suitable boron compounds (e.g., boron ester or boron oxide) and then heating the resultant composition with one or more inorganic phosphorus compounds; or 2) forming the ashless dispersant in the presence of one or more suitable inorganic phosphorus compounds (e.g., a phosphorus oxide or sulfide) and then heating the resultant composition with one or more boron compounds; or 3) forming the ashless dispersant in the presence of one or more suitable boron compounds (see 1) above) and one or more suitable inorganic phosphorus compounds (see 2) above); or 4) heating one or more boron compounds with a basic nitrogen-containing and/or hydroxyl group-containing reactant used in forming the ashless dispersant, using the resultant boronated reactant to form the ashless dispersant and then heating the resultant ashless dispersant with one or more inorganic phosphorus compounds; or 5) heating one or more inorganic phosphorus compounds with a basic nitrogen-containing and/or hydroxyl group-containing reactant used in forming the ashless dispersant, using the resultant phosphorylated reactant to form the ashless dispersant and then heating the resultant ashless dispersant with one or more boron compounds; or 6) heating one or more inorganic phosphorus compounds and one more boron compounds with a basic nitrogen-containing and/or hydroxyl group-containing reactant used in forming the ashless dispersant, and using the resultant phosphorylated and boronated reactant to form the ashless dispersant. In all cases, the final product composition [component a-1)] should be a liquid composition that on analysis reveals the presence of boron and phosphorus. Component a-2) Phosphorylated Ashless Dispersant The ashless dispersant which is used in the process is preferably a preformed ashless dispersant containing basic nitrogen and/or at least one hydroxyl group. Thus, for example, any suitable boron-free ashless dispersant formed in the customary manner can be heated with one or more inorganic phosphorus acids to cause phosphorylation to occur. The resulting liquid product composition when subjected to chemical analysis reveals the presence of phosphorus. Rather than utilizing a preformed ashless dispersant containing basic nitrogen and/or at least one hydroxyl group, it is possible to produce component a-2) by: 1) forming the ashless dispersant in the presence of one or more suitable inorganic phosphorus acids; or 2) heating one or more inorganic phosphorus acids with a basic nitrogen-containing and/or hydroxyl group-containing reactant used in forming the ashless dispersant, and using the resultant phosphorylated reactant to form the ashless dispersant. In all such cases, the final product composition [component a-2)] should be a liquid that on analysis reveals the presence of phosphorus. Component a-3) - Phosphorylated & Boronated Ashless Dispersant The ashless dispersant which is heated concurrently or in any sequence with components (i) and (ii) is preferably a preformed ashless dispersant containing basic nitrogen and/or at least one hydroxyl group. Thus, for example, any suitable ashless dispersant formed in the customary manner can be heated with one or more boron compounds to cause boronation to occur and the resultant product mixture can then be heated with water and one or more water-hydrolyzable organic phosphorus compounds such that a liquid phosphorus- and boron-containing composition [component a-3)] is formed. Conversely, a preformed ashless dispersant can be heated with water and one or more water-hydrolyzable organic phosphorus compounds and thereafter the product mixture can be heated with one or more boron compounds so that a liquid phosphorus- and boron-containing composition is formed. The preferred way of forming component a-3) is to heat a preformed ashless dispersant with a combination of water, one or more water-hydrolyzable organic phosphorus compounds and one or more boron compounds to form a liquid phosphorus- and boron-containing composition. In other words, to form component a-3) in the preferred manner, the preformed ashless dispersant is concurrently heated with water, one or more water-hydrolyzable organic phosphorus compounds and one or more boron compounds. In all cases, the resulting liquid product composition when subjected to chemical analysis reveals the presence of both phosphorus and boron. In the formation of the liquid phosphorus- and boron-containing composition, water is removed at least during or after the heating with (i) and (ii) (if conducted concurrently) or at least during or after the heating with (i) (if conducted sequentially). Such heating is conducted under conditions such that partial or total hydrolysis of the water-hydrolyzable organic phosphorus compound occurs. Rather than utilizing a preformed ashless dispersant containing basic nitrogen and/or at least one hydroxyl group, it is possible to produce component a-3) by: 1) forming the ashless dispersant in the presence of one or more boron compounds (e.g., boron ester or boron oxide) and then heating the resultant composition in the presence of water with one or more water-hydrolyzable organic phosphorus compounds; or 2) forming the ashless dispersant in the presence of one or more water-hydrolyzable organic phosphorus compounds and then heating the resultant composition with one or more boron compounds in the presence of water; or 3) forming the ashless dispersant in the presence of one or more boron compounds and one or more water-hydrolyzable organic phosphorus compounds and heating the ashless dispersant in the presence of water either during or after the formation of the ashless dispersant; or 4) heating one or more boron compounds with a basic nitrogen-containing and/or hydroxyl group-containing reactant used in forming the ashless dispersant, using the resultant boronated reactant to form the ashless dispersant and then heating the resultant ashless dispersant in the presence of water with one or more water-hydrolyzable organic phosphorus compounds; or 5) heating one or more water-hydrolyzable organic phosphorus compounds in the presence of water with a basic nitrogen-containing and/or hydroxyl group-containing reactant used in forming the ashless dispersant, using the resultant phosphorylated reactant to form the ashless dispersant and then heating the resultant ashless dispersant with one or more boron compounds; or 6) heating in the presence of water one or more water-hydrolyzable organic phosphorus compounds and one more boron compounds with a basic nitrogen-containing and/or hydroxyl group-containing reactant used in forming the ashless dispersant, and using the resultant phosphorylated and boronated reactant to form the ashless dispersant. In all cases, the final product composition [component a-3)] should be a liquid composition that on analysis reveals the presence of boron and phosphorus. Component a-4) - Phosphorylated Ashless Dispersant The ashless dispersant which is used in the process is preferably a preformed ashless dispersant containing basic nitrogen and/or at least one hydroxyl group. Thus, for example, any suitable boron-free ashless dispersant formed in the customary manner can be heated with water and one or more water-hydrolyzable organic phosphorus compounds to cause phosphorylation to occur. The resulting liquid product composition when subjected to chemical analysis reveals the presence of phosphorus. Rather than utilizing a preformed ashless dispersant containing basic nitrogen and/or at least one hydroxyl group, it is possible to produce component a-4) by: 1) forming the ashless dispersant in the presence of water and one or more suitable water-hydrolyzable organic phosphorus compounds (e.g., a phosphorus oxide or sulfide); or 2) heating water and one or more water-hydrolyzable organic phosphorus compounds with a basic nitrogen-containing and/or hydroxyl group-containing reactant used in forming the ashless dispersant, and using the resultant phosphorylated reactant to form the ashless dispersant. In all such cases, the final product composition [component a-4)] should be a liquid composition that on analysis reveals the presence of phosphorus. Various methods can be used for removing water from component a-3) or a-4) during or after its formation. The preferred method involves applying a suitable vacuum to the reaction system while heating the water-containing mixture to a suitably elevated temperature. In this way the water is readily stripped off. When conducting the phosphorylation using a phosphorus ester made from a lower alcohol such as methanol, ethanol, propanol, 2-propanol, butanol, or isobutyl alcohol, both lower alcohol liberated in the process and water can be stripped off from the product mixture during or on completion of the heating operation. In any case wherein an ashless dispersant used in forming component a) is not a liquid but rather is in whole or in part in the solid state of aggregation at room temperature (e.g., 25°C), it is preferable to dissolve such dispersant in a suitable solvent or diluent (polar or non-polar, as may be required to dissolve the dispersant) before the dispersant is subjected to phosphorylation and/or boronation (as the case may be) in forming component a-1) or a-3) or phosphorylation in forming component a-2) or a-4). In this connection, the phrase "such that a liquid composition is formed" as used herein in connection with such solid state dispersants means that component a), including such solvent or diluent, is in the liquid state of aggregation at room temperature (e.g., 25 25°C), even though at a lower temperature the dispersant may revert in whole or in part to the solid state. Of course in any case, component a-1) must be oil-soluble within the meaning of such term as set forth hereinafter. Irrespective of the method used in forming component a), in any instance wherein macro (i.e., non-dispersible) solids are formed or remain in the liquid composition after it has been formed, such solids should be removed, and can be readily removed, by any of a variety of conventional separation techniques such as filtration, centrifugation, or decantation. The actual chemical structures of all of the final product compositions used as component a) in the practice of this invention, however prepared, are not known with absolute certainty. While it is believed, and in some cases known, that phosphorus-containing moieties and boron-containing moieties are chemically bonded to the ashless dispersant, it is possible that in some cases component a) is in whole or in part a micellar structure containing phosphorus- and/or boron-containing species or moieties. Thus, this invention is not limited to, and should not be construed as being limited to, any specific structural configurations with respect to component a). As noted above, all that is required is that component a) is a liquid that is oil soluble and that if subjected to analysis reveals the presence of phosphorus and, in the case of a-1) and 1-3), boron. In addition, component a) should possess dispersant properties. Although any of a variety of standard methods can be used to analyze the dispersant for the presence of phosphorus or boron therein, it is desirable to use the analytical procedure set forth in ASTM D-4951. In this procedure it is convenient to use a Perkin-Elmer Plasma 40 Emission Spectrometer. The analyzing wavelengths for acceptable measurements are 213.618 nm and 249.773 nm for phosphorus and boron, respectively. Component a) may contain chemical species and/or moieties besides the phosphorus- and boron-containing species or moieties of a-1) or a-3) or the phosphorus-containing species and/or moieties of a-2) or a-4), such as, for example, nitrogen- and/or oxygen- and/or sulfur-containing species or moieties over and above the basic nitrogen and/or hydroxyl group(s) forming an essential part of the initial ashless dispersant itself. It is to be understood that organic phosphorus-containing compounds may be used along with inorganic phosphorus compounds in making component a-1) or a-2) and that inorganic phosphorus-containing compounds may be used along with water and one or more water-hydrolyzable organic phosphorus compounds in making component a-3) or a-4). Further, the inorganic phosphorus compound or compounds can be formed in situ, as, for example, by heating a mixture of phosphorus and sulfur to form a phosphorus sulfide, or by treating one or more organic phosphorus compounds to convert the same in whole or in part into one or more inorganic phosphorus compounds. The water-hydrolyzable organic phosphorus compound or compounds can also be formed in situ, as, for example, by heating a mixture of one or more alcohols or phenols with one or more phosphorus halides (e.g., PCl 3 , POCl 3 , PSCl 3 , RPCl 2 , ROPCl 2 , RSPCl 2 , RPOCl 2 , ROPOCl 2 , RSPOCl 2 , RPSCl 2 , ROPSCl 2 , RSPSCl 2 , R 2 PCl, (RO) 2 PCl, (RS) 2 PCl, (RO)(RS)PCl, R 2 POCl, (RO) 2 POCl, (RS) 2 POCl, (RO)(RS)POCl, R 2 PSCl, (RO) 2 PSCl, (RS) 2 PSCl, where each R is, independently, a hydrocarbyl group) and introducing water into the system in order to hydrolyze the water-hydrolyzable phosphorus ester so formed. As used herein, the term phosphorylated" means that the ashless dispersant has been heated with one or more inorganic phosphorus compounds [components a-1) and a-2)] or with one or more water-hydrolyzable organic phosphorus compounds and water [components a-3) and a-4)] such that the resultant product, on analysis, reveals the presence of phosphorus. Likewise, as used herein, the term "boronated" means that the ashless dispersant has been heated with one or more boron compounds such that the resultant product, on analysis, reveals the presence of boron. The terms "phosphorylated" and "boronated" are not to be construed as requiring that the resultant composition contain chemically bound phosphorus or boron. Any of avariety of ashless dispersants can be utilized in forming component a) of the compositions of this invention. These include the following types: Type A - Carboxylic Ashless Dispersants. These are reaction products of (i) an acylating agent such as a monocarboxylic acid, or a dicarboxylic or other polycarboxylic acid, or a derivative thereof, with (ii) one or more compounds which contain amine groups and/or hydroxyl groups, such that the acylated reaction product contains basic nitrogen and/or at least one hydroxyl group. These products, herein referred to as carboxylic ashless dispersants, are described in many patents. There are a number of sub-categories of carboxylic ashless dispersants. One such sub-category which constitutes a preferred type for use in the formation of component a) is composed of the polyamine succinamides and more preferably the polyamine succinimides in which the succinic group contains a hydrocarbyl substituent containing at least 30 carbon atoms. The polyamine used in forming such compounds contains at least one primary amino group capable of forming an imide group on reaction with a hydrocarbon-substituted succinic acid or acid derivative thereof such an anhydride, lower alkyl ester, acid halide, or acid-ester. The alkenyl succinimides may be formed by conventional methods such as by heating an alkenyl succinic anhydride, acid, acid-ester, acid halide, or lower alkyl ester with a polyamine containing at least one primary amino group. The alkenyl succinic anhydride may be made readily by heating a mixture of olefin and maleic anhydride to 180°-220°C. The olefin is preferably a polymer or copolymer of a lower monoolefin such as ethylene, propylene, 1-butene, and isobutene. The more preferred source of alkenyl group is from polyisobutene having a number average molecular weight of up to 100,000 or higher. In a still more preferred embodiment the alkenyl group is a polyisobutenyl group having a number average molecular weight (determined using the method described in detail hereinafter) of 500-5,000, and preferably 700-2,500, more preferably 700-1,400, and especially 800-1,300. The isobutene used in making the polyisobutene is usually (but not necessarily) a mixture of isobutene and other C 4 isomers such as 1-butene. Thus, strictly speaking, the acylating agent formed from maleic anhydride and "polyisobutene" made from such mixtures of isobutene and other C 4 isomers such as 1-butene, can be termed a "polybutenyl succinic anhydride" and a succinimide made therewith can be termed a "polybutenyl succinimide". However, it is common to refer to such substances as "polyisobutenyl succinic anhydride" and "polyisobutenyl succinimide", respectively. As used herein "polyisobutenyl" is used to denote the alkenyl moiety whether made from a highly pure isobutene or a more impure mixture of isobutene and other C 4 isomers such as 1-butene. Polyamines which may be employed in forming the ashless dispersant include any that have at least one primary amino group which can react to form an imide group. A few representative examples include branched-chain alkanes containing two or more primary amino groups such as tetraamino-neopentane polyaminoalkanols such as 2-(2-aminoethylamino)-ethanol and 2-[2-(2-aminoethylamino)-ethylamino]-ethanol; heterocyclic compounds containing two or more amino groups at least one of which is a primary amino group such as 1-(β-aminoethyl)-2-imidazolidone, 2-(2-aminoethylamino)-5-nitropyridine, 3-amino-N-ethylpiperidine, 2-(2-aminoethyl)-pyridine, 5-aminoindole, 3-amino-5-mercapto-1,2,4-triazole, and 4-(aminomethyl)-piperidine; and the alkylene polyamines such as propylene diamine, dipropylene triamine, di-(1,2-butylene)triamine, N-(2-aminoethyl)-1,3-propanediamine, hexamethylenediamine and tetra-(1,2-propylene)-pentamine. The most preferred amines are the ethylene polyamines which can be depicted by the formula H 2 N(CH 2 CH 2 NH) n H wherein n is an integer from one to ten. These include: ethylene diamine, diethylene triamine, triethylene tetramine, tetraethylene pentamine, pentaethylene hexamine, including mixtures thereof in which case n is the average value of the mixture. The ethylene polyamines which have a primary amine group at each end can form mono-alkenylsuccinimides and bis-alkenylsuccinimides. Commercially available ethylene polyamine mixtures usually contain minor amounts of branched species and cyclic species such as N-aminoethyl piperazine, N,N'-bis(aminoethyl)piperazine, N,N'-bis(piperazinyl)ethane, and like compounds. The preferred commercial mixtures have approximate overall compositions falling in the range corresponding to diethylene triamine to pentaethylene hexamine, mixtures generally corresponding in overall makeup to tetraethylene pentamine being most preferred. Methods for the production of polyalkylene polyamines are known. Thus especially preferred ashless dispersants for use in the present invention are the products of reaction of a polyethylene polyamine, e.g., mixture known in the trade as "triethylene tetramine" or "tetraethylene pentamine", with a hydrocarbon-substituted carboxylic acid or anhydride (or other suitable acid derivative) made by reaction of a polyolefin, preferably polyisobutene, having a number average molecular weight of 500 to 5,000, preferably 700 to 2,500, more preferably 700 to 1,400 and especially 800 to 1,300, with an unsaturated polycarboxylic acid or anhydride, e.g., maleic anhydride, maleic acid, or fumaric acid, including mixtures of two or more such substances. As used herein the term "succinimide" is meant to encompass the completed reaction product from reaction between the amine reactant(s) and the hydrocarbon-substituted carboxylic acid or anhydride (or like acid derivative) reactant(s), and is intended to encompass compounds wherein the product may have amide, amidine, and/or salt linkages in addition to the imide linkage of the type that results from the reaction of a primary amino group and an anhydride moiety. Residual unsaturation in the alkenyl group of the alkenyl succinimide may be used as a reaction site, if desired. For example the alkenyl substituent may be hydrogenated to form an alkyl substituent. Similarly the olefinic bond(s) in the alkenyl substituent may be sulfurized, halogenated, or hydrohalogenated. Ordinarily, there is little to be gained by use of such techniques, and thus the use of alkenyl succinimides as the precursor of component a) is preferred. Another sub-category of carboxylic ashless dispersants which can be used in forming component a) includes alkenyl succinic acid esters and diesters of polyhydric alcohols containing 2-20 carbon atoms and 2-6 hydroxyl groups. The alkenyl succinic portion of these esters corresponds to the alkenyl succinic portion of the succinimides described above including the same preferred and most preferred subgenus, e.g., alkenyl succinic acids and anhydrides, where the alkenyl group contains at least 30 carbon atoms and notably, polyisobutenyl succinic acids and anhydrides wherein the polyisobutenyl group has a number average molecular weight of 500 to 5,000, preferably 700 to 2,500, more preferably 700 to 1,400, and especially 800 to 1,300. As in the case of the succinimides, the alkenyl group can be hydrogenated or subjected to other reactions involving olefinic double bonds. Alcohols useful in preparing the esters include ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, propylene glycol, tripropylene glycol, glycerol, sorbitol, 1,1,1-trimethylol ethane, 1,1,1-trimethylol propane, 1,1,1-trimethylol butane, pentaerythritol, and dipentaerythritol. The succinic esters are readily made by merely heating a mixture of alkenyl succinic acid, anhydrides or lower alkyl (e.g., C 1 -C 4 ) ester with the alcohol while distilling out water or lower alkanol. In the case of acid-esters less alcohol is used. In fact, acid-esters made from alkenyl succinic anhydrides do not evolve water. Still another sub-category of carboxylic ashless dispersants useful in forming component a) comprises an alkenyl succinic ester-amide mixture. These may be made by heating the above-described alkenyl succinic acids, anhydrides or lower alkyl esters with an alcohol and an amine either sequentially or in a mixture. Alcohols and amines such as those described above are also useful in this embodiment. Additionally, linear and/or branched chain monohydric alcohols such as 1-butanol, 2-butanol, 2-methyl-1-propanol, pentanol, hexanol, octanol, decanol, lauryl alcohol, oleyl alcohol, eicosanol, or ethylene glycol monomethyl ether, can be used provided they are used with one or more polyamines. Alternatively, amino alcohols can be used alone or with the alcohol and/or amine to form the ester-amine mixtures. The amino alcohol can contain 2-20 carbon atoms, 1-6 hydroxy groups and 1-4 amine nitrogen atoms. Examples are ethanolamine, diethanolamine, N-ethanol-diethylene triamine, and trimethylol aminomethane. Here again, the alkenyl group of the succinic ester-amide can be hydrogenated or subjected to other reactions involving olefinic double bonds. Yet another sub-category of carboxylic ashless dispersants useful in forming component a) comprises the Mannich-based derivatives of hydroxyaryl succinimides. Such compounds can be made by reacting a polyalkenyl succinic anhydride with an aminophenol to produce an N-(hydroxyaryl) hydrocarbyl succinimide which is then reacted with an alkylene diamine or polyalkylene polyamine and an aldehyde (e.g., formaldehyde), in a Mannich-base reaction. Details of such synthesis are set forth in U.S. Pat. No. 4,354,950. As in the case of the other carboxylic ashless dispersants discussed above, the alkenyl succinic anhydride or like acylating agent is derived from a polyolefin, preferably a polyisobutene, having a number average molecular weight of 500 to 5,000, preferably 700 to 2,500, more preferably 700 to 1,400, and especially 800 to 1,200. Likewise, residual unsaturation in the polyalkenyl substituent group can be used as a reaction site as for example, by hydrogenation or sulfurization. Type B - Hydrocarbyl Polyamine Dispersants. This category of ashless dispersants which can be used in forming component a) is likewise well known to those skilled in the art and fully described in the literature. The hydrocarbyl polyamine dispersants are generally produced by reacting an aliphatic or alicyclic halide (or mixture thereof) containing an average of at least about 40 carbon atoms with one or more amines, preferably polyalkylene polyamines. In general the hydrocarbyl-substituted polyamines are high molecular weight hydrocarbyl-N-substituted polyamines containing basic nitrogen in the molecule. The hydrocarbyl group typically has a number average molecular weight in the range of 750-10,000, more usually in the range of 1,000-5,000. The hydrocarbyl radical may be aliphatic or alicyclic and, except for adventitious amounts of aromatic components in petroleum mineral oils, will be free of aromatic unsaturation. The hydrocarbyl groups will normally be branched-chain aliphatic, having 0-2 sites of unsaturation, and preferably from 0-1 site of ethylene unsaturation. The hydrocarbyl groups are preferably derived from petroleum mineral oil, or polyolefins, either homo-polymers or higher-order polymers, or 1-olefins of from 2-6 carbon atoms. Ethylene is preferably copolymerized with a higher olefin to insure oil solubility. Illustrative polymers include polypropylene, polyisobutylene, or poly-1-butene. The polyolefin group will normally have at least one branch per six carbon atoms along the chain, preferably at least one branch per four carbon atoms along the chain. These branched-chain hydrocarbons are readily prepared by the polymerization of olefins of from 3-6 carbon atoms and preferably from olefins of from 3-4 carbon atoms. In preparing the hydrocarbyl polyamine dispersants, rarely will a single compound having a defined structure be employed. With both polymers and petroleum-derived hydrocarbon groups, the composition is a mixture of materials having various structures and molecular weights. Therefore, in referring to molecular weight, number average molecular weights are intended. Furthermore, when speaking of a particular hydrocarbon group, it is intended that the group include the mixture that is normally contained within materials which are commercially available. For example, polyisobutylene is known to have a range of molecular weights and may include small amounts of very high molecular weight materials. Particularly preferred hydrocarbyl-substituted amines or polyamines are prepared from polyisobutenyl chloride. The polyamine employed to prepare the hydrocarbyl-substituted polyamine is preferably a polyamine having from 2 to 12 amine nitrogen atoms and from 2 to 40 carbon atoms. The polyamine is reacted with a hydrocarbyl halide (e.g., chloride) to produce the hydrocarbyl-substituted polyamine. The polyamine preferably has a carbon-to-nitrogen ratio of from 1:1 to 10:1. The amine portion of the hydrocarbyl-substituted amine may be substituted with substituents selected from (A) hydrogen and (B) hydrocarbyl groups of from 1 to 10 carbon atoms. The polyamine portion of the hydrocarbyl-substituted polyamine may be substituted with substituents selected from (A) hydrogen, (B) hydrocarbyl groups of from 1 to 10 carbon atoms, (C) acyl groups of from 2 to 10 carbon atoms, and (D) monoketo, monohydroxy, mononitro, monocyano, lower alkyl and lower alkoxy derivatives of (B) and (C). "Lower" as used in terms like lower alkyl or lower alkoxy, means a group containing from 1 to 6 carbon atoms. At least one of the nitrogens in the hydrocarbyl-substituted amine or polyamine is a basic nitrogen atom, i.e., one titratable by a strong acid. Hydrocarbyl, as used in describing the substituents in the amine or polyamine used in forming the dispersants, denotes an organic radical composed of carbon and hydrogen which may be aliphatic, alicyclic, aromatic or combinations thereof, e.g., aralkyl. Preferably, the hydrocarbyl group will be relatively free of aliphatic unsaturation, i.e., ethylenic and acetylenic, particularly acetylenic unsaturation. The hydrocarbyl substituted polyamines used in forming the dispersants are generally, but not necessarily, N-substituted polyamines. Exemplary hydrocarbyl groups and substituted hydrocarbyl groups which may be present in the amine portion of the dispersant include alkyls such as methyl, ethyl, propyl butyl, isobutyl, pentyl, hexyl, octyl, etc., alkenyls such as propenyl isobutenyl, hexenyl, octenyl, etc., hydroxyalkyls, such as 2-hydroxyethyl, 3-hydroxypropyl, hydroxyisopropyl, 4-hydroxybutyl, etc., ketoalkyls, such as 2-ketopropyl, 6-ketooctyl, etc., alkoxy and lower alkenoxy alkyls, such as ethoxyethyl, ethoxypropyl, propoxyethyl, propoxypropyl, 2-(2-ethoxyethoxy)ethyl, 2-(2-(2-ethoxyethoxy)ethoxy)ethyl,3,6,9,12-tetraoxytetradecyl,2-(2-ethoxyethoxy)hexyl, etc. Typical amines useful in preparing the hydrocarbyl-substituted amines include methylamine, dimethylamine, ethylamine, diethylamine, n-propylamine, di-n-propylamine, etc. Such amines are either commercially available or are prepared by art recognized procedures. The polyamine component may also contain heterocyclic polyamines, heterocyclic substituted amines and substituted heterocyclic compounds, wherein the heterocyclic comprises one or more 5-6 membered rings containing oxygen and/or nitrogen. Such heterocyclics may be saturated or unsaturated and substituted with groups selected from the aforementioned (A), (B), (C), and (D). The heterocyclics are exemplified by piperazines, such as 2-methylpiperazine, 1,2-bis(N-piperazinyl-ethane), and N,N'-bis(N-piperazinyl)piperazine, 2-methylimidazoline, 3-aminopiperidine, 2-aminopyridine, 2-(β-aminoethyl)-3-pyrroline, 3-aminopyrrolidine, N(3-aminopropyl)morpholine, etc. Among the heterocyclic compounds, the piperazines are preferred. Typical polyamines that can be used to form the hydrocarbyl polyamine dispersants include the following: ethylene diamine, 1,2-propylene diamine, 1,3-propylene diamine, diethylene triamine, triethylene tetramine, hexamethylene diamine, tetraethylene pentamine, methylaminopropylene diamine, N-(β-aminoethyl)piperazine, N,N'-di(β-aminoethyl)piperazine, N,N'-di(β-aminoethyl)imidazolidone-2, N-(β-cyanoethyl)ethane-1,2-diamine, 1,3,6,9-tetraaminooctadecane, 1,3,6-triamino-9-oxadecane, N-methyl-1,2-propanediamine, and 2-(2-aminoethylamino)ethanol. Another group of suitable polyamines are the polyalkylene amines in which the alkylene groups differ in carbon content, such as for example bis(aminopropyl)ethylenediamine. Such compounds are prepared by the reaction of acrylonitrile with an ethyleneamine, for example, an ethyleneamine having the formula H 2 H(CH 2 CH 2 NH) n H wherein n is an integer from 1 to 5, followed by hydrogenation of the resultant intermediate. Thus, the product prepared from ethylene diamine and acrylonitrile has the formula H 2 N-(CH 2 ) 3 NH(CH 2 ) 2 NH(CH 2 ) 3 NH 2 . In many instances the polyamine used as a reactant in the production of the hydrocarbyl-substituted polyamine is not a single compound but a mixture in which one or several compounds predominate with the average composition indicated. For example, tetraethylene pentamine prepared by the polymerization of aziridine or the reaction of 1,2-dichloroethane and ammonia will have both lower and higher amine members, e.g., triethylene tetramine, substituted piperazines and pentaethylene hexamine, but the composition will be largely tetraethylene pentamine and the empirical formula of the total amine composition will closely approximate that of tetraethylene pentamine. Finally, in preparing the hydrocarbyl-substituted polyamines for use in this invention, where the various nitrogen atoms of the polyamine are not geometrically equivalent, several substitutional isomers are possible and are encompassed with the final product Methods of preparation of polyamines and their reactions are detailed in Sidgewick, The Organic Chemistry of Nitrogen , Clarendon Press, Oxford, 1966; Nollier, Chemistry of Organic Compounds , Saunders Philadelphia, 2nd Ed., 1957; and Kirk-Othmer, Encyclopedia of Chemical Technology , 2nd Edition, especially volume 2, pp. 99-116. The preferred hydrocarbyl-substituted polyalkylene polyamines for use in this invention may be represented by the formula R 1 NH(-R 2 NH-) α -H wherein R 1 is hydrocarbyl having an average molecular weight of from 750 to 10,000; R 2 is alkylene of from 2 to 6 carbon atoms; and α is an integer of from 0 to 10. Preferably, R 1 is hydrocarbyl having an average molecular weight of from 1,000 to 10,000. Preferably, R 2 is alkylene of from 2 to 3 carbon atoms and α is preferably an integer of from 1 to 6. Type C - Mannich polyamine dispersants. This category of ashless dispersant which can be utilized in the formation of component a) is comprised of reaction products of an alkyl phenol, with one or more aliphatic aldehydes containing from 1 to 7 carbon atoms (especially formaldehyde and derivatives thereof), and polyamines (especially polyalkylene polyamines of the type described hereinabove). The polyamine group of the Mannich polyamine dispersants is derived from polyamine compounds characterized by containing a group of the structure -NH- wherein the two remaining valances of the nitrogen are satisfied by hydrogen, amino, or organic radicals bonded to said nitrogen atom. These compounds include aliphatic, aromatic, heterocyclic and carbocyclic polyamines. The source of the oil-soluble hydrocarbyl group in the Mannich polyamine dispersant is a hydrocarbyl-substituted hydroxy aromatic compound comprising the reaction product of a hydroxy aromatic compound, according to well known procedures, with a hydrocarbyl donating agent or hydrocarbon source. The hydrocarbyl substituent provides substantial oil solubility to the hydroxy aromatic compound and, preferably, is substantially aliphatic in character. Commonly, the hydrocarbyl substituent is derived from a polyolefin having at least about 40 carbon atoms. The hydrocarbon source should be substantially free from pendant groups which render the hydrocarbyl group oil insoluble. Examples of acceptable substituent groups are halide, hydroxy, ether, carboxy, ester, amide, nitro and cyano. However, these substituent groups preferably comprise no more than about 10 weight percent of the hydrocarbon source. The preferred hydrocarbon sources for preparation of the Mannich polyamine dispersants are those derived from substantially saturated petroleum fractions and olefin polymers, preferably polymers of mono-olefins having from 2 to 30 carbon atoms. The hydrocarbon course can be derived, for example, from polymers of olefins such as ethylene, propene, 1-butene, isobutene, 1-octene, 1-methylcyclohexene, 2-butene and 3-pentene. Also useful are copolymers of such olefins with other polymerizable olefinic substances such as styrene. In general these copolymers should contain at least 80 percent and preferably 95 percent, on a weight basis, of units derived from the aliphatic mono-olefins to preserve oil solubility. The hydrocarbon source generally contains at least 40 and preferably at least 50 carbon atoms to provide substantial oil solubility to the dispersant. The olefin polymers having a number average molecular weight between 600 and 5,000 are preferred for reasons of easy reactivity and low cost However, polymers of higher molecular weight can also be used. Especially suitable hydrocarbon sources are isobutylene polymers. The Mannich polyamine dispersants are generally prepared by reacting a hydrocarbyl-substituted hydroxy aromatic compound with an aldehyde and a polyamine. The aldehyde is typically an aliphatic aldehyde containing 1 to 7 carbon atoms, and in most cases is formaldehyde or a compound such as formalin or a polyformaldehyde from which formaldehyde is derived during the reaction. Typically, the substituted hydroxy aromatic compound is contacted with from 0.1 to 10 moles of polyamine and 0.1 to 10 moles of aldehyde per mole of substituted hydroxy aromatic compound. The reactants are mixed and heated to a temperature above about 80°C. to initiate the reaction. Preferably, the reaction is carried out at a temperature from 100° to 250°C. The resulting Mannich product has a predominantly benzylamine linkage between the aromatic compound and the polyamine. The reaction can be carried out in an inert diluent such as mineral oil, benzene, toluene, naphtha, ligroin, or other inert solvents to facilitate control of viscosity, temperature, and reaction rate. Polyamines are preferred for use in preparing the Mannich polyamine dispersants, and suitable polyamines include, but are not limited to, alkylene diamines and polyalkylene polyamines (and mixtures thereof) of the formula: wherein n is an integer from 1 to 10, R is a divalent hydrocarbyl group of from 1 to 18 carbon atoms, and each A is independently selected from the group consisting of hydrogen and monovalent aliphatic groups containing up to 10 carbon atoms which can be substituted with one or two hydroxyl groups. Most preferably, R is a lower alkylene group of from 2 to 6 carbon atoms and A is hydrogen. Suitable polyamines for use in preparation of the Mannich polyamine dispersants include, but are not limited to, methylene polyamines, ethylene polyamines, butylene polyamines, propylene polyamines, pentylene polyamines, hexylene polyamines and heptylene polyamines. The higher homologs of such amines and related aminoalkyl-substituted piperazines are also included. Specific examples of such polyamines include ethylene diamine, triethylene tetramine, tris(2-aminoethyl)amine, propylene diamine, pentamethylene diamine, hexamethylene diamine, heptamethylene diamine, octamethylene diamine, decamethylene diamine, di(heptamethylene) triamine, pentaethylene hexamine, di(trimethylene) triamine, 2-heptyl-3-(2-aminopropyl)imidazoline, 1,3-bis(2-aminoethyl)imidazoline, 1-(2-aminopropyl)piperazine, 1,4-bis(2-aminoethyl)piperazine and 2-methyl-1(2-aminobutyl)piperazine. Higher homologs, obtained by condensing two or more of the above mentioned amines, are also useful, as are the polyoxyalkylene polyamines. The polyalkylene polyamines, examples of which are set forth above, are especially useful in preparing the Mannich polyamine dispersants for reasons of cost and effectiveness. Such polyamines are described in detail under the heading "Diamines and Higher Amines" in Kirk-Othmer, Encyclopedia of Chemical Technology , Second Edition, Vol. 7, pp. 22-39. They are prepared most conveniently by the reaction of an ethylene imine with a ring-opening reagent such as ammonia. These reactions result in the production of somewhat complex mixtures of polyalkylene polyamines which include cyclic condensation products such as piperazines. Because of their availability, these mixtures are particularly useful in preparing the Mannich polyamine dispersants. However, it will be appreciated that satisfactory dispersants can also be obtained by use of pure polyalkylene polyamines. Alkylene diamines and polyalkylene polyamines having one or more hydroxyalkyl substituents on the nitrogen atom are also useful in preparing the Mannich polyamine dispersants. These materials are typically obtained by reaction of the corresponding polyamine with an epoxide such as ethylene oxide or propylene oxide. Preferred hydroxyalkyl-substituted diamines and polyamines are those in which the hydroxyalkyl groups have less than about 10 carbon atoms. Examples of suitable hydroxyalkyl-substituted diamines and polyamines include, but are not limited to, N-(2-hydroxyethyl)ethylenediamine, N,N'-bis(2-hydroxyethyl)ethylenediamine, mono(hydroxypropyl)diethlenetriamine, (di(hydroxypropyl)tetraethylenepentamine and N-(3-hydroxybutyl)tetramethylenediamine. Higher homologs obtained by condensation of the above mentioned hydroxyalkyl-substituted diamines and polyamines through amine groups or through ether groups are also useful. Any conventional formaldehyde yielding reagent is useful for the preparation of the Mannich polyamine dispersants. Examples of such formaldehyde yielding reagents are trioxane, paraformaldehyde, trioxymethylene, aqueous formalin and gaseous formaldehyde. Other aldehydes which can be used include acetaldehyde, propionaldehyde, butyraldehyde, isobutyraldehyde, valeraldehyde, hexanal, heptanal, and mixtures of two or more of these. The most preferred Mannich base dispersants for use in this invention are Mannich base ashless dispersants formed by condensing about one molar proportion of long chain hydrocarbon-substituted phenol with from 1 to 2.5 moles of formaldehyde and from 0.5 to 2 moles of polyalkylene polyamine. Type D - Polymeric polyamine dispersants. Also suitable for preparing component a) of the compositions of this invention are polymers containing basic amine groups and oil solubilizing groups (for example, pendant alkyl groups having at least about 8 carbon atoms). Such polymeric dispersants are herein referred to as polymeric polyamine dispersants. Such materials include, but are not limited to, interpolymers of decyl methacrylate, vinyl decyl ether or a relatively high molecular weight olefin with aminoalkyl acrylates and aminoalkyl acrylamides. Type E - Post-treated basic nitrogen-containing and/or hydroxyl-containing ashless dispersants . As is well known in the art, any of the ashless dispersants referred to above as types A-D can be subjected to post-treatment with one or more suitable reagents such as urea, thiourea, carbon disulfide, aldehydes, ketones, carboxylic acids, anhydrides of low molecular weight dibasic acids, nitriles, and epoxides. Such post-treated ashless dispersants can be used in forming component a) of the compositions of this invention provided that the post-treated dispersant contains residual basic nitrogen and/or one or more residual hydroxyl groups. Alternatively, the phosphorylated or the phosphorylated and boronated dispersant can be subjected to post-treatment with such reagents. Likewise, in the case of components a-1) and a-3) the post-treatment can be conducted in between the phosphorylation and boronation or conversely, between the boronation and the phosphorylation. Mannich-based derivatives of hydroxyaryl succinimides that have been post-treated with C 5 -C 9 lactones such as ε-caprolactone and optionally with other post-treating agents as described for example in U.S. Pat. No. 4,971,711 can also be utilized in forming component a) for use in the practice of this invention, provided that such post-treated Mannich-based derivatives of hydroxyaryl succinimides contain basic nitrogen, and/or at least one hydroxyl group. One preferred category of post-treated ashless dispersants is comprised of basic nitrogen-containing and/or hydroxyl group-containing ashless dispersants which have been heated with (1) a phosphorus compound such that they contain phosphorus, or (2) a boron compound such that they contain boron, all with the proviso that such post-treated products contain residual basic nitrogen and/or one or more residual hydroxyl groups. Numerous examples of such dispersants and methods for their production are described in the patent literature. The boron-containing post-treated ashless dispersants of the prior art type can be converted into a material suitable for use as component a-1) or a-3) simply by conducting a phosphorylation in the manner described herein. If desired, additional boron can also be incorporated into a prior art type post-treated boron-containing ashless dispersant by conducting a boronation in the manner described herein either before, during or after the phosphorylation. It is also possible by using the phosphorylation and/or boronation procedures described herein to phosphorylate and/or boronate a post-treated ashless dispersant that already contains phosphorus and/or boron, provided that such initial post-treated ashless dispersant contains at least some residual basic nitrogen and/or at least some residual hydroxyl substitution. The ashless dispersant(s) used in forming component a) can be any mixture containing any two or more ashless dispersants containing basic nitrogen and/or at least one hydroxyl group. Because of environmental and conservational concerns it is desirable to employ ashless dispersants which contain little, if any, halogen atoms such as chlorine atoms. Thus, in order to satisfy such concerns, it is desirable (although not necessary from a performance standpoint) to select ashless dispersants (as well as the other components used in the compositions of this invention) such that the total halogen content, if any, of the overall lubricant or functional fluid composition does not exceed 100 ppm. Indeed, the lower the better. Likewise, it is preferable in accordance with this invention, to provide additive concentrates which, when dissolved in a halogen-free base oil, at a concentration of 10% by weight, yield an oleaginous composition in which the total halogen content, if any, is 100 ppm or less. Production of Component a-1) : Typical procedures for producing component a-1) phosphorylated and boronated ashless dispersants involve concurrently or sequentially heating one or more ashless dispersants of the types described above with at least one inorganic phosphorus compound and at least one boron compound under conditions yielding a liquid phosphorus- and boron-containing composition. Examples of inorganic phosphorus compounds which are useful in forming such products include phosphorous acid (H 3 PO 3 , sometimes depicted as H 2 (HPO 3 ), and sometimes called ortho-phosphorous acid or phosphonic acid), phosphoric acid (H 3 PO 4 , sometimes called orthophosphoric acid), hypophosphoric acid (H 4 P 2 O 6 ), metaphosphoric acid (HPO 3 ), pyrophosphoric acid (H 4 P 2 O 7 ), hypophosphorous acid (H 3 PO 2 , sometimes called phosphinic acid), pyrophosphorous add (H 4 P 2 O 5 , sometimes called pyrophosphonic acid), phosphinous acid (H 3 PO), tripolyphosphoric acid (H 5 P 3 O 10 ), tetrapolyphosphoric acid (H 6 P 4 O 13 ), trimetaphosphoric acid (H 3 P 3 O 9 ), phosphorus trioxide, phosphorus tetraoxide, and phosphorus pentoxide. Partial or total sulfur analogs such as phosphorotetrathioic acid (H 3 PS 4 ), phosphoromonothioic acid (H 3 PO 3 S), phosphorodithioic acid (H 3 PO 2 S 2 ), phosphorotrithioic acid (H 3 POS 3 ), phosphorus sesquisulfide, phosphorus heptasulfide, and phosphorus pentasulfide (P 2 S 5 , sometimes referred to as P 4 S 10 ) can also be used in forming products suitable for use as component a-1) in the practice of this invention. Also usable, though less preferred, are the inorganic phosphorus halide compounds such as PCl 3 , PBr 3 , POCl 3 , PSCl 3 , etc. The preferred phosphorus reagent is phosphorous acid, (H 3 PO 3 ). It will be understood and appreciated by those skilled in the art that the form or composition of the inorganic compound(s) as charged into the mixture to be heated or being heated may be altered in situ. For example, the action of heat and/or water can transform certain inorganic phosphorus compounds into other inorganic phosphorus compounds or species. Any such in situ transformations that may occur are within the purview of this invention provided that the liquid phosphorylated ashless dispersant reveals on analysis the presence therein of phosphorus (as well as boron). Suitable compounds of boron useful in forming the phosphorylated and boronated ashless dispersants for use as component a-1) include, for example, boron acids, boron oxides, boron esters, and amine or ammonium salts of boron acids. Illustrative compounds include boric acid (sometimes referred to as orthoboric acid), boronic acid, tetraboric acid, metaboric acid, pyroboric acid, esters of such acids, such as mono-, di-, and tri-organic esters with alcohols or polyols having up to 20 or more carbon atoms (e.g., methanol, ethanol, 2-propanol, propanol, butanols, pentanols, hexanols, ethylene glycol, propylene glycol, trimethylol propane, diethanol amine, etc.), boron oxides such as boric oxide and boron oxide hydrate, and ammonium salts such as ammonium borate, ammonium pyroborate, etc. While usable, boron halides such as boron trifluoride, and boron trichloride, are undesirable as they tend to introduce halogen atoms into the boronated dispersant, a feature which is detrimental from the environmental, toxicological and conservational standpoints. Amine borane addition compounds and hydrocarbyl boranes can also be used, although they tend to be relatively expensive. The preferred boron reagent is boric acid, H 3 BO 3 . Optionally, additional sources of basic nitrogen can be included in the inorganic phosphorus compound-ashless dispersant-boron compound mixture so as to provide a molar amount (atomic proportion) of basic nitrogen up to that equal to the molar amount of basic nitrogen contributed by the ashless dispersant. Preferred auxiliary nitrogen compounds are long chain primary, secondary and tertiary alkyl amines containing from 12 to 24 carbon atoms, including their hydroxyalkyl and aminoalkyl derivatives. The long chain alkyl group may optionally contain one or more ether groups. Examples of suitable compounds are oleyl amine, N-oleyltrimethylene diamine, N-tallow diethanolamine, N,N-dimethyl oleylamine, and myristyloxapropyl amine. Other materials normally used in lubricant additives which do not interfere with the process may also be added, for example, a benzotriazole, including lower (C 1 -C 4 ) alkyl-substituted benzotriazoles, which function to protect copper surfaces. The concurrent heating step or the combination of sequential heating steps is conducted at temperatures sufficient to produce a final liquid composition which contains both phosphorus and boron. The heating can be carried out in the absence of a solvent by heating a mixture of the ashless dispersant and one or more suitable inorganic phosphorus compounds, or one or more suitable boron compounds, or, preferably, a combination of one or more suitable inorganic phosphorus compounds and one or more suitable boron compounds. The temperatures used will vary somewhat depending upon the nature of the ashless dispersant and the inorganic phosphorus and/or boron reagent being utilized. Generally speaking however, the temperature will usually fall within the range of 40 to 200°C. The duration of the heating is likewise susceptible to variation, but ordinarily will fall in the range of 1 to 3 hours. When conducting the heating in bulk, it is important to thoroughly agitate the components to insure intimate contact therebetween. When utilizing the preferred phosphorus and boron reagents (phosphorous acid and boric acid), it is preferable to add water to facilitate initial dissolution of the boric acid. Alternatively, the phosphorous acid may be utilized in the form of an aqueous solution thereby introducing water into the system to facilitate dissolution of the boric acid. Water (and when using boron esters, alcohol) formed in the process and any added water is preferably removed from the heated mixture by vacuum distillation at temperatures of from 100 to 140°C. Preferably the heating step or steps will be conducted in a diluent oil or other inert liquid medium such as light mineral oils, etc. The amount of phosphorus compound employed in the heating process ranges from 0.001 mole to 0.999 mole per mole of basic nitrogen and free hydroxyl in the mixture being heated, up to one half of which may be contributed by an auxiliary nitrogen compound. The amount of boron compound employed ranges from 0.001 mole to 1 mole per mole of basic nitrogen and/or hydroxyl in the mixture which is in excess of the molar amount of inorganic phosphorus compound. When conducting the phosphorylation and boronation on a sequential basis (or when conducting one of these operations on a dispersant which has previously been subjected to the other such operation), the last-to-be-used reagent(s) -- inorganic phosphorus compound(s) or boron compound(s), as the case may be -- can be used in an amount equivalent to (or even in excess of) the amount of basic nitrogen and/or hydroxyl groups in the dispersant being heated with such last-to-be-used reagent(s). When used, the amount of added water is not particularly critical as it is removed by distillation during the course of, or at the end of, the heating step. Amounts of up to 1% by weight of the mixture being heated are preferred. When used, the amount of diluent usually ranges from 10 to 50% by weight of the mixture being subjected to heating. When conducting the preferred concurrent heating step for production of component a-1), it is desirable to employ procedures such as described in U.S. Pat. No. 4,857,214. For further details concerning procedures for conducting the boronation operation apart from the phosphorylation operation, reference may be had, for example, to the disclosures of U.S. Pat. Nos. 3,087,936; 3,254,025; 3,281,428; 3,282,955; 3,284,410; 3,338,832; 3,344,069; 3,533,945; 3,718,663; 4,097,389; 4,554,086; and 4,634,543. The phosphorylated and boronated dispersants utilized as component a-1) in the compositions of this invention when in their undiluted state should have on a weight basis a phosphorus content of at least 100 parts per million (ppm) (preferably at least 500 ppm and more preferably at least 1,000 ppm) and a boron content of at least 100 ppm (preferably at least 500 ppm and more preferably at least 1,000 ppm). When forming component a-1) in part by use of one or more organic phosphorus compounds such as one or more organic phosphates (e.g., trihydrocarbyl phosphates, dihydrocarbyl monoacid phosphates, monohydrocarbyl diacid phosphates, or mixtures thereof), phosphites (e.g., trihydrocarbyl phosphites, dihydrocarbyl hydrogen phosphites, hydrocarbyl diacid phosphites, or mixtures thereof), phosphonates (e.g., hydrocarbyl phosphonic acids, mono- and/or dihydrocarbyl esters of phosphonic acids, or mixtures thereof), phosphonites (e.g., hydrocarbyl phosphinic acids, mono- and/or dihydrocarbyl esters of phosphinic acids, or mixtures thereof), etc., or the partial or total sulfur analogs thereof, and in part by use of one or more inorganic phosphorus compounds, the latter should be used in an amount sufficient to provide at least 10% (preferably at least 50% and more preferably at least 75%) of the total content of phosphorus in the phosphorylated and boronated dispersant For crankcase lubricant usage, component a-1) when in the undiluted state preferably contains at least 3,000 ppm (more preferably at least 5,000 ppm and most preferably at least 7,000 ppm) of phosphorus and at least 1,500 ppm (more preferably at least 2,500 ppm and most preferably at least 3,500 ppm) of boron. The preparation of phosphorylated and boronated ashless dispersants suitable for use as component a-1) in the compositions of this invention is illustrated by the following Examples 1-4 in which all parts and percentages are by weight unless otherwise clearly specified. EXAMPLE 1 A mixture is formed from 260 parts of a commercial succinimide ashless dispersant (HiTEC® 644 dispersant; Ethyl Petroleum Additives, Inc.; Ethyl Petroleum Additives, Ltd.; Ethyl S.A.; Ethyl Canada Limited), 100 parts of a 100 Solvent Neutral refined mineral oil diluent, 8 parts of phosphorous acid, 3.5 parts of tolutriazole, 8 parts of boric acid, and 3.0 parts of water. The mixture is heated at 100°C for two hours until all of the solid materials are dissolved. A vacuum of 40 mm Hg is gradually drawn on the product to remove the water while the temperature is slowly raised to 100°C. A clear solution or composition is obtained which is soluble in oil and suitable for use as component a-1). EXAMPLE 2 The procedure of Example 1 is repeated except that the succinimide ashless dispersant is replaced by an equal amount of a Mannich polyamine dispersant (AMOCO® 9250 dispersant; Amoco Corporation). The Amoco 9250 dispersant as supplied by the manufacturer is believed to be a boronated dispersant and in such case, another material suitable for use as component a-1) can be formed by eliminating the boric acid and water from the procedure used in this example and thereby conducting phosphorylation on an already boronated dispersant. EXAMPLE 3 (a) A mixture of 1,000 parts (0.495 mole) of polyisobutene ( M n = 2020; M w = 6049, both determined using the methodology of U.S. Pat. No. 4,234,435) and 115 parts (1.17 moles) of maleic anhydride is heated to 110°C. This mixture is heated to 184°C in 6 hours during which 85 parts (1.2 moles) of gaseous chlorine is added beneath the surface. At 184-189°C, an additional 59 parts (0.83 mole) of chlorine is added over 4 hours. The reaction mixture is stripped by heating at 186-190°C with nitrogen purged for 26 hours. The residue is predominantly polyisobutenyl succinic anhydride acylating agent (b) A mixture is prepared by the addition of 18.2 parts (0.433 equivalents) of a commercial mixture of ethylene polyamines having the approximate overall composition of tetraethylene pentamine to 392 parts of mineral oil and 348 parts (0.52 equivalent) of substituted succinic acylating agent prepared as in (a) while maintaining the temperature at 140°C. The reaction mixture is then heated to 150°C in 1.8 hours and stripped by blowing with nitrogen. The reaction mixture is filtered to yield the filtrate as an oil solution of the desired product composed predominantly of polyisobutenyl succinimides. (c) A mixture is formed from 250 parts of the polyisobutenyl succinimide product solution formed as in (b), 8 parts of phosphorous acid, 3.5 parts of tolutriazole, 8 parts of boric acid, and 3.0 parts of water. The mixture is heated at 100°C for two hours until all of the solid materials are dissolved. A vacuum of 40 mm Hg is gradually drawn on the product to remove the water while the temperature is slowly raised to 100°C. A clear solution or composition is obtained which is soluble in oil and suitable for use as component a-1). EXAMPLE 4 To a reactor are charged under a nitrogen atmosphere 67.98 parts of a commercially-available polyisobutenyl succinimide of a mixture of polyethylene polyamines having the approximate overall composition of tetraethylene pentamine (the polyisobutenyl group derived from polyisobutene having a number average molecular weight of about 900; the succinimide product having a ratio of about 1.15 succinic groups per alkenyl group) and 26.14 parts of a 100 Solvent neutral refined mineral oil. After raising the temperature of the resulting solution to 100-105 C, 2.09 parts of boric acid and 2.09 parts of phosphorous acid are introduced into the reactor, followed by 0.92 part of tolutriazole (Cobratec TT-100; PMC Specialties Group, Cincinnati, Ohio) and then 0.78 part of water. The resultant mixture is heated at 100-105 °C for two hours and then the temperature is gradually raised to 115°C with the application of a vacuum to 40 mm Hg. Stripping is continued for 90 minutes and until 120°C/40 mm Hg has been reached. A flow of dry nitrogen is then applied to the system and the product mixture is allowed to cooL The product mixture is suitable for use as component a-1) in the compositions of this invention. Production of Component a-2): Typical procedures for producing component a-2) phosphorylated ashless dispersants involve heating one or more ashless dispersants of the types described above with at least one inorganic phosphorus acid under conditions yielding a liquid phosphorus-containing composition. Examples of inorganic phosphorus acid which are useful in forming such products include those described above in connection with component a-1). Partial or total sulfur analogs such as phosphorotetrathioic acid (H 3 PS 4 ), phosphoromonothioic acid (H 3 PO 3 S), phosphorodithioic acid (H 3 PO 2 S 2 ), phosphorotrithioic acid (H 3 POS 3 ), can also be used in forming products suitable for use as component a-2). The preferred phosphorus reagent is phosphorous acid, (H 3 PO 3 ). Optionally, additional sources of basic nitrogen can be included in the inorganic phosphorus compound-ashless dispersant mixture so as to provide a molar amount (atomic proportion) of basic nitrogen up to that equal to the molar amount of basic nitrogen contributed by the ashless dispersant. Preferred auxilary nitrogen compounds are as described above inconnection with component a-1). Other materials normally used in lubricant additives which do not interfere with the process may also be added, for example, a benzotriazole, including lower (C 1 -C 4 ) alkyl-substituted benzotriazoles, which function to protect copper surfaces. The heating step is conducted at temperatures sufficient to produce a liquid composition which contains phosphorus and is as described above in connection with component a-1). When utilizing the preferred phosphorus reagent (solid phosphorous acid), it is convenient to apply heat to the mixture until a clear liquid composition is formed. Alternatively, the phosphorous add may be utilized in the form of an aqueous solution. Water formed in the process and any added water is preferably removed from the heated mixture by vacuum distillation at temperatures of from 100 to 140°C. The heating may be conducted in more than one stage if desired. Preferably the heating step or steps will be conducted in a diluent oil or other inert liquid medium such as light mineral oils, and the like. The amount of inorganic phosphorus acid employed in the heating process is preferably as described above in connection with component a-1) When used, the amount of diluent usually ranges from 10 to 50% by weight of the mixture being subjected to heating. Water can be added to the mixture, before and/or during the heating, if desired. Usually the phosphorylated dispersants utilized as component a-2) in the compositions of this invention when in their undiluted state will have on a weight basis a phosphorus content of at least 5,000 parts per million (ppm) (preferably at least 6,000 ppm and more preferably at least 7,000 ppm). When forming component a-2) in part by use of one or more organic phosphorus compounds such as one or more organic phosphates (e.g., trihydrocarbyl phosphates, dihydrocarbyl monoacid phosphates, monohydrocarbyl diacid phosphates, or mixtures thereof), phosphites (e.g., trihydrocarbyl phosphites, dihydrocarbyl hydrogen phosphites, hydrocarbyl diacid phosphites, or mixtures thereof), phosphonates (e.g., hydrocarbyl phosphonic acids, mono- and/or dihydrocarbyl esters of phosphonic acids, or mixtures thereof), phosphonites (e.g, hydrocarbyl phosphinic acids, mono- and/or dihydrocarbyl esters of phosphinic acids, or mixtures thereof), etc, or the partial or total sulfur analogs thereof, and in part by use of one or more inorganic phosphorus acids, the latter should be used in an amount sufficient to provide at least 25% (preferably at least 50% and more preferably at least 75%) of the total content of phosphorus in the phosphorylated dispersant. The preparation of phosphorylated ashless dispersants suitable for use as component a-2) in the compositions of this invention is illustrated by the following Examples 5 -9 in which all parts and percentages are by weight unless otherwise clearly specified. EXAMPLE 5 A mixture is formed from 260 parts of a polyisobutenyl succinimide ashless dispersant (derived from polybutene having a number average molecular weight of 950 and a mixture of a polyethylene polyamines having an average overall composition approximating that of tetraethylene pentamine), 100 parts of a 100 Solvent Neutral refined mineral oil diluent, 8 parts of solid phosphorous acid, and 3.5 parts of tolutriazole. The mixture is heated at 110°C for two hours. A vacuum of 40 mm Hg is gradually drawn on the product to remove traces of water while the temperature is maintained at 110°C. A clear solution or composition is obtained which is soluble in oil and suitable for use as component a-2). EXAMPLE 6 The procedure of Example 5 is repeated except that the succinimide ashless dispersant is replaced by an equal amount of a boron-free Mannich polyamine dispersant made from tetraethylene pentamine, polyisobutenyl phenol (made from polyisobutene having a number average molecular weight of about 1710 and formalin) having a nitrogen content of 1.1% EXAMPLE 7 A mixture of 7300 parts of a polyisobutenyl succinimide (derived from polybutene having a number average molecular weight of about 1,300 and a mixture of polyethylene polyamines having an average overall composition approximating that of tetraethylene pentamine), and 2500 parts of 100 Solvent Neutral mineral oil is heated to 90-100°C. To this mixture is added 200 parts of phosphorous acid and the resultant mixture is heated at 90-100°C for 2 hours. The resultant homogeneous liquid composition is suitable for use as component a-2). EXAMPLE 8 (a) A mixture of 1,000 parts (0.495 mole) of polyisobutene ( M n = 2020; M w = 6049, both determined using the methodology of U.S. Pat. No. 4,234,435) and 115 parts (1.17 moles) of maleic anhydride is heated to 110°C. This mixture is heated to 184°C in 6 hours during which 85 parts (1.2 moles) of gaseous chlorine is added beneath the surface. At 184-189°C, an additional 59 parts (0.83 mole) of chlorine is added over 4 hours. The reaction mixture is stripped by heating at 186-190°C with nitrogen purged for 26 hours. The residue is predominately polyisobutenyl succinic anhydride acylating agent (b) A mixture of 334 parts (0.52 equivalents) of the polyisobutene substituted succinic acylating agent prepared as in (a), 548 parts of mineral oil, 30 parts (0.88 equivalent) of pentaerythritol and 8.6 parts (0.0057 equivalent) of Polyglycol 112-2 demulsifier is heated at 150°C for 2.5 hours. The reaction mixture is then heated to 210°C over a period of 5 hours and then held at 210°C for an additional 32 hours. The reaction mixture is cooled to 190°C and 8.5 parts (0.2 equivalent) of a commercial mixture of ethylene polyamines having an overall composition approximating that of tetraethylene pentamine is added.

The mixture is heated at 100°C for two hours. A clear solution or composition is obtained which is soluble in oil and suitable for use as component a-2). EXAMPLE 9 (a) A mixture of 510 parts (028 mole) of polysobutene ( M n = 1845; M w = 5325, both determined using the methodology of U.S. Pat. No. 4,234,435) and 59 parts (0.59 mole) of maleic anhydride is heated to 110°C. This mixture is heated to 190°C in 7 hours during which 43 parts (0.6 mole) of gaseous chlorine is added beneath the surface. At 190-192°C, an additional 11 parts (0.16 mole) of chlorine is added over 35 hours. The reaction mixture is stripped by heating at 190-193°C with nitrogen blowing for 10 hours. The residue is predominately polyisobutenyl succinic anhydride acylating agent (b) A mixture of 334 parts (0.52 equivalents) of the polyisobutene substituted succinic acylating agent prepared as in (a), 548 parts of mineral oil 30 parts (0.88 equivalent) of pentaerythritol and 8.6 parts (0.0057 equivalent) of Polyglycol 112-2 demulsifier is heated at 150°C for 2.5 hours. The reaction mixture is then heated to 210°C over a period of 5 hours and then held at 210°C for an additional 3.2 hours. The reaction mixture is cooled to 190°C and 8.5 parts (0.2 equivalent) of a commercial mixture of ethylene polyamines having an overall composition approximating that of tetraethylene pentamine is added. The reaction mixture is stripped by heating at 205°C with nitrogen blowing for 3 hours, and then filtered to yield the filtrate as an oil solution of the desired ashless dispersant product. (c) A mixture is formed from 260 parts of the ashless dispersant product solution formed as in (b), 8 parts of phosphorous acid, and 3.5 parts of tolutriazole. The mixture is heated at 100°C for two hours. A clear solution or composition is obtained which is soluble in oil and suitable for use as component a-2). Production of Component a-3): Typical procedures for producing component a-3) phosphorylated and boronated ashless dispersants involve concurrently or sequentially heating one or more ashless dispersants of the types described above with (i) water and at least one water-hydrolyzable organic phosphorus compound and (ii) at least one boron compound under conditions yielding a liquid phosphorus- and boron-containing composition. Examples of organic phosphorus compounds which are useful in forming such products include mono-, di-, and triesters of phosphoric acid (e.g., trihydrocarbyl phosphates dihydrocarbyl monoacid phosphates, monohydrocarbyl diacid phosphates, and mixtures thereof), mono-, di-, and triesters of phosphorous acid (e.g., trihydrocarbyl phosphites, dihydrocarbyl hydrogen phosphites, hydrocarbyl diacid phosphites, and mixtures thereof), esters of phosphonic acids (both "primary", RP(O)(OR) 2 , and "secondary", R 2 P(O)(OR)), esters of phosphinic acids, phosphonyl halides (e.g, RP(O)Cl 2 and R 2 P(O)Cl), halophosphites (e.g., (RO)PCl 2 and (RO) 2 PCl), halophosphates (e.g., ROP(O)Cl 2 and (RO) 2 P(O)Cl), tertiary pyrophosphate esters (e.g., (RO) 2 P(O)-O-P(O)(OR) 2 ), and the total or partial sulfur analogs of any of the foregoing organic phosphorus compounds, and the like. Also usable, although less preferred, are the halophosphine halides (e.g., hydrocarbyl phosphorus tetra-halides, dihydrocarbyl phosphorus trihalides, and trihydrocarbyl phosphorus dihalides), and the halophosphines (monohalophosphines and dihalophosphines). By "water-hydrolyzable" is meant that the organic phosphorus compound when boiled at atmospheric pressure for a period of 5 hours with either (a) distilled water, or (a) water adjusted to at least one pH between 1 and 7 by use of H 2 SO 4 , or (c) water adjusted to at least one pH between 7 and 13 with KOH, is hydrolyzed to the extent of at least 50 mole %. In some cases, hydrolysis of certain types of organophosphorus compounds results in concomitant oxidation, and compounds which undergo both hydrolysis and oxidation under the foregoing conditions are usable in forming the phosphorylated dispersants for use in this invention. Likewise, certain sulfur-containing organophosphorus compounds undergo loss of sulfur under hydrolysis conditions. Here again, compounds of this type are suitable for use in forming the phosphorylated dispersants used in the practice of this invention. Considerable information exists in the literature concerning hydrolysis of organophosphorus compounds. The preferred water-hydrolysable organic phosphorus compounds are the water-hydrolysable phosphate esters, and the water-hydrolysable phosphite esters, especially the dihydrocarbyl hydrogen phosphites. Suitable compounds of boron useful in forming the phophorylated and boronated ashless dispersants for use as component a-3) include, for example those described above in connection with component a-1). While usable, boron halides such as boron trifluoride, boron trichloride, and the like, are undesirable as they tend to introduce halogen atoms into the boronated dispersant, a feature which detrimental from the environmental, toxicological and conservational standpoints. The preferred boron reagent is boric acid, H 3 BO 3 . Optionally, additional sources of basic nitrogen can be included in the organic phosphorus compound-ashless dispersant-boron compound-water mixture so as to provide a molar amount (atomic proportion) of basic nitrogen up to that equal to the molar amount of basic nitrogen contributed by the ashless as described above in connection with component a-1). Other materials normally used in lubricant additives which do not interfere with the process may also be added, for example, a benzotriazole, including lower (C 1 -C 4 ) alkyl-substituted benzotriazoles, which function to protect copper surfaces. The concurrent heating step or the combination of sequential heating steps is conducted at temperatures sufficient to produce a final liquid composition which contains both phosphorus and boron and is as described above in connection with component a-1). When utilizing the preferred boron reagent (boric acid) in a boronation conducted separately from the phosphorylation, it is preferable to add water with the boric acid to facilitate initial dissolution of the boric acid. Water and relatively volatile alcohols formed in the hydrolysis process and the added water are preferably removed from the heated mixture by vacuum distillation at temperatures of from 100 to 140°C. Preferably the heating step or steps will be conducted in a diluent oil or other inert liquid medium such as light mineral oils, and the like. The amount of phosphorus compound and boron compound is as described above in connection with component a-1). When conducting the phosphorylation and boronation on a sequential basis (or when conducting one of these operations on a dispersant which has previously been subjected to the other), the last-to-be-used reagent(s) -- water and organic phosphorus compound(s) or boron compound (s), as the case may be -- can be used in an amount equivalent to (or even in excess of) the amount of basic nitrogen and/or hydroxyl groups in the dispersant being heated with such last-to-be-used reagent(s). As noted above, insotar as the phosphorylation is concerned, it is preferable to heat the ashless dispersant with one or more water-hydrolyzable organic phosphorus compounds in the presence of water. In this case the water can be added before and/or during the heating step, and before, after, or at the same time one or more phosphorus compounds are introduced into the vessel in which the heating is taking place or is to take place. It is also possible to heat the ashless dispersant with the organic phosphorus compound and then subsequently heat the resultant composition with water, although this procedure is less preferred. The amount of added water is not particularly critical as long as a sufficient amount is present to effect hydrolysis of the water-hydrolyzable organic phospnorus compound. Water present in the system can be removed by distillation (preferably at reduced pressure) during the course of, and preferably is removed at the end of, the heating step. Amounts of water up to 15% by weight of the mixture being heated are preferred, and amounts of water of up to 5% by weight are particularly preferred. When used, the amount of diluent usually ranges from 10 to 50% by weight of the mixture being subjected to heating. The hydrolysis of the water-hydrolyzable organic phosphorus compound(s) employed in the phosphorylation operation can be effected in any of a variety of ways. For example, the dispersant to be phosphorylated, one or more water-hydrolyzable organic phosphorus compounds, and water may be mixed together and heated either in an open system at atmospheric pressure or in a closed system at superatmospheric pressure. If conducted with an open system, the temperature may be kept below the boiling point of water and the mixture subjected to stirring of sufficient intensity to cause and maintain intimate contact among the components within the hydrolysis reaction mixture. It is also feasible to raise the temperature of the mixture in an open system to the boiling point of water and allow the water vapor either to escape from the system or to be condensed in a suitable condensing system and returned to the refluxing hydrolysis reaction mixture. If the water is allowed to escape, sufficiently large amounts of water should be used to insure that a substantial amount of hydrolysis occurs before the supply of water in the hydrolysis mixture has been depleted. In all such cases, water can be fed to the system as an initial complete charge or it can be fed intermittently or continuously into the hydrolysis mixture. When conducting the hydrolysis in a closed system, the system may be kept at one or more selected autogenous pressures by suitable adjustment and regulation of the temperature. And, still higher pressures may be imposed upon the system, as for example by injecting high pressure steam into a sealed autoclave containing the hydrolysis reaction mixture. The water itself may be charged to the system in any suitable form, such as in the form of liquid water, steam, or even ice. Similarly, the water may be introduced in the form of hydrated solids so that the water is released by the application of heat during the course of the hydrolysis operation. Injection of wet steam into a well-agitated hydrolysis system is one preferred way of conducting the operation. The hydrolysis operation should be conducted under any given set or sequence of hydrolysis conditions for a period of time long enough that at least 10%, preferably at least 50%, and most preferably at least 75%, of the organic phosphorus compound(s) present in the hydrolysis mixture has been hydrolyzed. The nature of the hydrolysis products can be expected to vary in relation to the type of phosphorus compound(s) used and the severity of the hydrolysis conditions imposed upon the hydrolysis system Thus inorganic and organic hydrolysis products can be formed in the system, and these in turn can be expected to be taken up by the ashless dispersant(s) present in the system substantially as they are formed Accordingly, although the chemical structure(s) of the phosphorylated dispersant(s) are not known with absolute certainty, it is reasonable to conclude that at least some interaction occurs between the dispersant(s) and organic and/or inorganic phosphorus-containing species formed in the hydrolysis reactions taking place in the system. It is also conceivable that such interacted components may undergo displacements and/or other forms of interactions with components present in the hydrolysis system as the hydrolysis operation proceeds. As pointed out above, the phosphorylation may be conducted apart from the boronation, or it may be conducted concurrently with the boronation. When performing the phosphorylation and boronation operations concurrently, any of the foregoing hydrolysis procedures can be utilized, the principal difference being that one or more boron compounds are used in combination with one or more water-hydrolyzable organic phosphorus compounds. If desired, small amounts of one or more acids (e.g., sulfuric acid, phosphoric acid phosphorous acid, etc.) or bases (e.g., NaOH, KOH, ammonium hydroxide, etc.) may be added to the hydrolysis mixture to facilitate hydrolysis of the organic phosphorus compound(s) being used. The phosphorylated and boronated dispersants utilized as component a-3) in the compositions of this invention when in their undiluted state should have on a weight basis a phosphorus content of at least 100 parts per million (ppm) (preferably at least 500 ppm and more preferably at least 1000 ppm) and a boron content of at least 100 ppm (preferably at least 500 ppm and more preferably at least 1000 ppm). When forming component a-3) in part by use of one or more inorganic phosphorus compounds such as those described above in connection with component a-1), trimetaphosphoric acid (H 3 P 3 O 9 ), phosphorus trioxide, phosphorus tetroxide, phosphorus pentoxide, and/or partial or total sulfur analogs as described above in connection with component a-1), and in part by use of one or more water-hydrolyzable organic phosphorus compounds, the latter should be used in an amount sufficient to provide at least 10% (preferably at least 50% and more preferably at least 75%) of the total phosphorus content of the phosphorylated and boronated dispersant. For crankcase lubricant usage, component a-3) when in the undiluted state preferably contains at least 3000 ppm (more preferably at least 5000 ppm and most preferably at least 7000 ppm) of phosphorus and at least 1500 ppm (more preferably at least 2500 ppm and most preferably at least 3500 ppm) of boron. The preparation of phosphorylated and boronated ashless dispersants suitable for use as component a-3) in the compositions of this invention is illustrated by the following Examples 10 and 11 in which all parts and percentages are by weight unless otherwise clearly specified. EXAMPLE 10 To a reactor are charged under a nitrogen atmosphere 67.98 parts of a commercially-available polyisobutenyl succinimide of a mixture of polyethylene polyamines having the approximate overall composition of tetraethylene pentamine (the polyisobutenyl group derived from polyisobutene having a number average molecular weight of about 900; the succinimide product having a ratio of about 1.15 succinic groups per alkenyl group) and 26.14 parts of a 100 Solvent neutral refined mineral oil. After raising the temperature of the resulting solution to 100-105°C, 2.09 parts of boric acid and 4.6 parts of dibutyl hydrogen phosphite are introduced into the reactor, followed by 0.92 part of tolutriazole (Cobratec TT-100) and then 3 parts of water. The resultant mixture is heated at 100-105°C for two hours and then the temperature is gradually raised to 115°C with the application of a vacuum to 40 mm Hg. Stripping is continued for 90 minutes and until 120°C/40 mm Hg has been reached. A flow of dry nitrogen is then applied to the system and the product mixture is allowed to cool. The product mixture is suitable for use as component a-3). EXAMPLE 11 (a) A mixture of 510 parts (0.28 mole) of polyisobutene ( M n = 1845; M w = 5325, both determined using the methodology of U.S. Pat. No. 4,234,435) and 59 parts (059 mole) of maleic anhydride is heated to 110°C. This mixture is heated to 190°C in 7 hours during which 43 parts (0.6 mole) of gaseous chlorine is added beneath the surface. At 190-192°C, an additional 11 parts (0.16 mole) of chlorine is added over 35 hours. The reaction mixture is stripped by heating at 190-193°C with nitrogen blowing for 10 hours. The residue is predominantly polyisobutenyl succinic anhydride acylating agent. (b) A mixture of 322 parts of the polyisobutene-substituted succinic acylating agent prepared as in (a) above, 68 parts of pentaerythritol and 508 parts of mineral oil is heated at 204-227°C for 5 hours. The reaction mixture is cooled to 162°C and 5.3 parts of a commercial ethylene polyamine mixture having the approximate overall composition corresponding to tetraethylene pentamine is added. The reaction mixture is heated at 162-163°C for 1 hour, then cooled to 130°C and filtered. The filtrate is an oil solution of the desired product. (c) A mixture is formed from 275 parts of the product solution formed as in (b), 20 parts of diisopropyl hydrogen phosphite, 3.5 parts of tolutriazole, 8 parts of boric acid, and 8 parts of water. The mixture is heated at 100°C for two hours until all of the solid materials are dissolved. A vacuum of 40 mm Hg is gradually drawn on the product to remove the water while the temperature is slowly raised to 100°C. A clear solution or composition is obtained which is soluble in oil and suitable for use as component a-3). Production of Component a-4): Typical procedures for producing component a4) phosphorylated ashless dispersants involve heating one or more ashless dispersants of the types described above with at least one water-hydrolyzable organic phosphorus compound and water under conditions yielding a liquid phosphorus-containing composition. The water-hydrolyzable organic phosphorus compounds used and the conditions under which they are used are the same as described above in connection with production of component a-3), except of course no boron compound is employed in the process. Usually the phosphorylated dispersants utilized as component a-4) in the compositions of this invention when in their undiluted state will have on a weight basis a phosphorus content of at least 5,000 parts per million (ppm) (preferably at least 6,000 ppm and more preferably at least 7,000 ppm). The preparation of phosphorylated ashless dispersants suitable for use component a-4) in the compositions of this invention is illustrated by the Examples 12-15 in which all parts and percentages are by weight unless otherwise clearly specified. EXAMPLE 12 A mixture is formed from 260 parts of a polyisobutenyl succinimide ashless dispersant (derived from polybutene having a number average molecular weight of about 950 and a mixture of a polyethylene polyamines having an average overall composition approximating that of tetraethylene pentamine), 100 parts of a 100 Solvent Neutral refined mineral oil diluent, 26 parts of dibutyl hydrogen phosphite, 35 parts of tolutriazole and 8 parts of water. The mixture is heated at 110°C for two hours. A vacuum of 40 mm Hg is gradually drawn on the product to remove water and butanol while the temperature is maintained at 110°C. A clear solution or composition is obtained which is soluble in oil and suitable for use as component a-4). EXAMPLE 13 The procedure of Example 12 is repeated except that the succinimide ashless dispersant is replaced by an equal amount of a boron-free Mannich polyamine dispersant made from tetraethylene pentamine, polyisobutenyl phenol (made from polyisobutene having a number average molecular weight of about 1710 and formalin) having a nitrogen content of 1.1%. EXAMPLE 14 A mixture of 260 parts of a commercial succinimide (HiTEC® 644 dispersant), 3 parts of water, 13 parts of tributyl phosphate, and 4 parts of phosphorous acid is heated to 100°C for 2 hours. Then a vacuum of 40 mm of Hg is applied to the system and the temperature is gradually raised to 110°C. (b) A mixture of 46.8 parts of the homogeneous liquid phosphorylated dispersant formed as in part (a) above and 23.4 parts of a commercial boronated succinimide ashless dispersant (HiTEC®648 dispersant)is formed. The resultant homogeneous liquid composition is suitable for use in the practice of this invention. A portion of the resultant mixture can be heated to 110°C for two hours, and this resultant homogeneous liquid composition is also suitable for use as component a-4) in the practice of this invention. EXAMPLE 15 To a reactor are charged under a nitrogen atmosphere 67.98 parts of a commercially-available polyisobutenyl succinimide of a mixture of polyethylene polyamines having the approximate overall composition of tetraethylene pentamine (the polyisobutenyl group derived from polyisobutene having a number average molecular weight of about 900; the succinimide product having a ratio of about 1.15 succinic groups per alkenyl group) and 26.14 parts of a 100 Solvent Neutral refined mineral oil. After raising the temperature of the resulting solution to 100-105°C, 4.6 parts of dibutyl hydrogen phosphite is introduced into the reactor, followed by 0.92 part of tolutriazole (Cobratec TT-100), and then 3 parts of water. The resultant mixture is heated at 100-105°C for two hours and then the temperature is gradually raised to 115°C with the application of a vacuum to 40 mm Hg. Stripping is continued for 90 minutes and until 120°C/4.0 mm Hg has been reached. A flow of dry nitrogen is then applied to the system and the product mixture is allowed to cool. The product mixture is suitable for use as component a-4). A particularly preferred embodiment of this invention involves using as component a-1) and a-3) a phosphorylated and boronated alkenyl succinimide of a polyethylene polyamine or mixture of polyethylene polyamines, wherein the succinimide is formed from (i) an alkenyl succinic acylating agent having a succination ratio (i.e., the ratio of the average number of chemically bound succinic groups per alkenyl group in the molecular structure of the succinic acylating agent) in the range of 1 to 1.3, the alkenyl group being derived from a polyolefin (most preferably a polyisobutene) having a number average molecular weight in the range of 600 to 1,300 (more preferably in the range of 700 to 1,250 and most preferably in the range of 800 to 1,200). Another particularly preferred embodiment of this invention involves using as component a-2) and a4) a phosphorylated alkenyl succinimide of a polyethylene polyamine or mixture of polyethylene polyamines, wherein the succinimide is formed from (i) an alkenyl succinic acylating agent having a succination ratio (i.e., the ratio of the average number of chemically bound succinic groups per alkenyl group in the molecular structure of the succinic acylating agent) in the range of 1 to 13, the alkenyl group being derived from a polyolefin (most preferably a polyisobutene) having a number average molecular weight in the range of 600 to 1,300 (more preferably in the range of 700 to 1,250 and most preferably in the range of 800 to 1,200). To determine the succination ratio of the alkenyl succinic acylating agents utilized in forming such particularly preferred ashless dispersants: A. The number average molecular weight ( M n) of the polyalkene from which the substituent is derived is determined by use of either of two methods, namely, vapor pressure osmometry (VPO) or gel permeation chromatography (GPC). The VPO determination should be conducted in accordance with ASTM D-2503-82 using high purity toluene as the measuring solvent Alternatively, a GPC procedure can be employed. As is well known, the GPC technique involves separating molecules according to their size in solution. For this purpose liquid chromatographic columns are packed with a styrene-divinyl benzene copolymer of controlled particle and pore sizes. When the polyalkene molecules from which the substituent is derived are transported through the GPC columns by a solvent (tetrahydrofuran), the polyalkene molecules small enough to penetrate into the pores of the column packing are retarded in their progress through the columns. On the other hand, the polyalkene molecules which are larger either penetrate the pores only slighly or are totally excluded from the pores. As a consequence, these larger polyalkene molecules are retarded in their progress through the columns to a lesser extent Thus a velocity separation occurs according to the size of the respective polyalkene molecules. In order to define the relationship between polyalkene molecular weight and elution time, the GPC system to be used is calibrated using known molecular weight polyalkene standards and an internal standard method. Details concerning such GPC procedures and methods for column calibration are extensively reported in the literature. See for example, W. W. Yau, J. J. Kirkland, and D. D. Bly, Modern Size-Exclusion Liquid Chromatography, John Wiley & Sons, 1979, Chapter 9 (pages 285-341), and references cited therein. B. The total weight of the substituent groups present in the substituted succinic acylating agent is determined by conventional methods for determination of the number of carbonyl functions. The preferred procedure for use involves nonaqueous titration of the substituted acylating agent with standardized sodium isopropoxide. In this procedure the titration is conducted in a 1:1 mineral spirits:1-butanol solvent system. An alternative, albeit less preferred, procedure is the ASTM D-94 procedure. The results from procedures A and B above are used in calculating the weight of substituent groups per unit weight of total sample. C. In determining the succination ratio of the alkenyl succinic acylating agents, the determination is to be based on the active portion of the sample. That is to say, alkenyl succinic acylating agents are often produced as a mixture with an inactive diluent. Thus for the purpose of succination ratio determination, such diluent should not be considered a part of the succinic acylating agent, and accordingly a separation as between the diluent and the alkenyl succinic acylating agent should be accomplished. Such separation can be effected before determination of total weight of the subtituent groups present in the substituted succinic acylating agent However, it is preferable to effect such separation after such determination using a mathematical correction of the result The separation itself can be achieved using a silica gel column separation technique. A low molecular weight non-polar hydrocarbon solvent, such as hexane and more preferably pentane, is used as the solvent whereby the unreactive diluent is readily eluted from the column. The substituted succinic acylating agent entrained in the column can then be recovered by use of a more polar elution solvent, preferably methanol/methylene dichloride. Component b) - Metal-Free Sulfur-Containing Antiwear and/or Extreme Pressure Agent A variety of oil-soluble metal-free sulfur-containing antiwear and/or extreme pressure additives can be used as the other indispensable component in the practice of this invention, provided they have the requisite minimum sulfur content of at least 20 wt %. Examples are included within the categories of dihydrocarbyl polysulfides; sulfurized olefins; trithiones; sulfurized thienyl derivatives; sulfurized terpenes; sulfurized oligomers of C 2 -C 8 monoolefins; xanthates; hydrocarbyl trithiocarbonates; and sulfurized Diels-Alder adducts such as those disclosed in U.S. reissue patent Re 27,331. Specific examples include sulfurized polyisobutene of M n 1,100, sulfurized isobutylene, sulfurized diisobutylene, sulfurized triisobutylene, dicyclohexyl polysulfide, diphenyl polysulfide, dibenzyl polysulfide, dinonyl polysulfide, and mixtures of di-tert-butyl polysulfide such as mixtures of di-tert-butyl trisulfide, di-tert-butyl tetrasulfide and di-tert-butyl pentasulfide, among others. Combinations of such categories of sulfur-containing antiwear and/or extreme pressure agents can also be used, such as a combination of sulfurized isobutylene and di-tert-butyl trisulfide, a combination of sulfurized isobutylene and dinonyl trisulfide, a combination of sulfurized triisobutylene and dibenzyl polysulfide. The preferred sulfur-containing antiwear and/or extreme pressure agents are the oil-soluble active sulfur-containing antiwear and/or extreme pressure agents. Generally speaking, these are substances which possess a linkage of two or more sulfur atoms (e.g., -S-S-, -S-S-S-, -S-S-S-S-, -S-S-S-S-S-, etc.). To determine for the purpose of this invention whether a sulfur-containing material is an active sulfur-containing material, use can be made of a copper coupon corrosion test conducted as follows: A copper coupon approximately 70 x 15 mm and about 1.25 mm in thickness is cleaned by use of steel wool (0000 grade), washed with heptane, and then with acetone, dried, and weighed to the nearest 0.1 mg. The cleaned coupon is placed in a test tube and covered completely with the composition to be tested, and the system is heated to 125°C by means of an oil bath. After holding the system at 125°C for three hours, the copper coupon is removed from the test tube, rinsed with heptane, and then with acetone. The dried coupon is then rubbed with a paper towel moistened with acetone to remove any surface flakes formed by copper corrosion. The coupon is then air-dried and weighed to the nearest 0.1 mg, The difference in weight between the initial copper coupon and the coupon after the test represents the extent to which the copper was corroded under the test conditions. Therefore the larger the weight difference, the greater the copper corrosion, and thus the more active the sulfur compound. For the purposes of this invention, if the coupon weight loss is 30 milligrams or more, the sulfur-containing agent is considered "active". Oil-soluble sulfur-containing antiwear and/or extreme pressure agents yielding a weight loss of above 50 mg in the above test are more preferred. Another test which can be used for determining the activity of a sulfur-containing additive for use as component b) is the 4-Ball EP test, listed as ASTM D 2783-88, (Measurement of Extreme Pressure Properties of Lubricating Fluids). In general, the higher the weld point in the test, the more active is the sulfur-containing additive. Thus a sulfur additive at 1% (wt) concentration achieving or exceeding 250 kilograms weld point is deemed active for the purposes of this invention. Because of the toxicity of hydrogen sulfide, it is important to utilize in the practice of this invention oil-soluble sulfur-containing antiwear and/or extreme pressure agents, and more preferably oil-soluble active sulfur-containing antiwear and/or extreme pressure agents, that yield less than 25 ppm, and more preferably less than 10 ppm, and most preferably no detectable amounts, of vapor space H 2 S when heated in the concentrated state for one week at 65°C. HiTEC® 309 and 312 sulfurized isobutylene additives (Ethyl Petroleum Additives, Inc.; Ethyl Petroleum Additives, Ltd.; Ethyl S.A.; Ethyl Canada Ltd.) are especially desirable in this respect. The most preferred oil-soluble metal-free sulfur-containing antiwear and/or extreme pressure agents from the cost-effectiveness standpoint are the sulfurized olefins containing at least 30% by weight of sulfur, the dihydrocarbyl polysulfides containing at least 25% by weight of sulfur, and mixtures of such sulfurized olefins and polysulfides. Of these materials, di-tert-alkyl polysulfides having a sulfur content of at least 35% by weight are particularly desirable. Sulfurized isobutylene having a sulfur content of at least 40% and as much as 50% by weight or more and a chlorine content of less than 1% by weight is the most especially preferred material. Methods of preparing sulfurized olefins are described -in U.S. Pat. Nos. 2,995,569; 3,673,090; 3,703,504; 3,703,505; 3,796,661; 3,873,454; 4,795,576; 4,954,274; and 4,966,720. Also useful are the sulfurized olefin derivatives described in U.S. Pat. No. 4,654,156. Component c) - Amine Salt of Mono- and/or Dihydrocarbyl Ester of a Monomeric Pentavalent Acid of Phosphorus This optional but preferred component is composed of one or more oil-soluble amine salts of one or more partial esters of one or more phosphoric acids and/or thiophosphoric acids. Such compounds may be collectively represented by the formulae or mixtures thereof. In Formulae I, II and III, each of R 1 , R 2 , R 3 , R 4 , R 5 , R 6 ,and R 7 is, independently, a hydrocarbyl group and each of X 1 , X 2 , X 3 , X 4 , X 5 , X 6 , X 7 , X 8 , X 9 , X 10 , X 11 , and X 12 is, independently, an oxygen atom or a sulfur atom. In one preferred sub-category the amine salts are formed with one or more partially esterified monothiophosphoric acids. These are compounds of Formulae (I), (II), and (III) above wherein only one of X 1 , X 2 , X 3 , and X 4 , only one of X 5 , X 6 , X 7 , and X 8 , and only one of X 9 , X 10 , X 11 , and X 12 is a sulfur atom. In another preferred sub-category the amine salts are formed with one or more partially esterified phosphoric acids. These are compounds of Formulae (I), (II), and (III) above wherein all of X 1 , X 2 , X 3 , X 4 , X 5 , X 6 , X 7 , X 8 , X 9 , X 10 , X 11 , and X 12 are oxygen atoms. Another preferred sub-category of amine salts are those formed with one or more partially esterified dithiophosphoric acids. These are compounds of Formulae (I), (II), and (III) above wherein two of X 1 , X 2 , X 3 , and X 4 , two of X 5 , X 6 , X 7 , and X 8 , and two of X 9 , X 10 , X 11 , and X 12 are sulfur atoms. Also useful are amine salts of Formulae (I), (II), and (III) above wherein three or four of X 1 , X 2 , X 3 , and X 4 , three or four of X 5 , X 6 , X 7 , and X 8 , and three or four of X 9 , X 10 , X 11 , and X 12 are sulfur atoms. While all of the above oil-soluble amine salts are useful as components in the compositions of this invention, it is most preferred to include at least one oil-soluble amine salt of a dihydrocarbyl monothiophosphoric acid (one sulfur atom per molecule), either alone or in combination with at least one oil-soluble amine salt of a dihydrocarbyl phosphoric acid (no sulfur atom in the molecule). Use can be made of the octylamine, nonylamine, decylamine, undecylamine, dodecylamine, tridecylamine, tetradecylamine, pentadecylamine, hexadecylamine, heptadecylamine, octadecylamine, cyclohexylamine, phenylamine, mesitylamine, oleylamine, cocoamine, soyamine, C 12-14 tertiary alkyl primary amine, C 22-24 tertiary alkyl primary amine, and phenethylamine salts or adducts of the above and similar partially esterified acids of monothiophosphoric acid, including mixtures of any such compounds. Generally speaking, the preferred amine salts are salts of aliphatic amines, especially the saturated or olefinically unsaturated aliphatic primary amines, such as n-octylamine, 2-ethylhexylamine, tert-octylamine, n-decylamine, the C 10 , C 12 , C 14 and C 16 tertiary alkyl primary amines (either singly or in any combinations thereof, such as a mixture of the C 12 and C 14 tertiary alkyl primary amines), n-undecylamine, lauryl amine, hexadecylamine, heptadecylamine, octadecylamine, the C 22 and C 24 tertiary alkyl primary amines (either singly or in combination), decenylamine, dodecenylamine, palmitoleylamine, oleylamine, linoleylamine, eicosenylamine, etc. Secondary hydrocarbyl amines and teniary hydrocarbyl amines can also be used either alone or in combination with each other or in combination with primary amines. Thus any combination of primary, secondary and/or tertiary amines, whether monoamine or polyamine, can be used in forming the salts or adducts. Use of primary amines is preferred. Especially preferred amines are alkyl monoamines and alkenyl monoamines having from 8 to 24 carbon atoms in the molecule. Methods for the preparation of such amine salts are well known and reported in the literature. Amine salts of partially esterified monothiophosphoric acids are usually made by reacting a mono- and/or dihydrocarbyl phosphite with sulfur or an active sulfur-containing compound such as are referred to above under the caption "Sulfur-Containing Antiwear and/or Extreme Pressure Agents" and one or more primary or secondary amines. Such reactions tend to be highly exothermic reactions which can become uncontrollable, if not conducted properly. One preferred method of forming these amine salts involves a process which comprises (i) introducing, at a rate such that the temperature does not exceed about 60°C, one or more dihydrocarbyl hydrogen phosphites, such as a dialkyl hydrogen phosphite, into an excess quantity of one or more active sulfur-containing materials, such as sulfurized branched-chain olefin (e.g., isobutylene, diisobutylene, triisobutylene, etc.), while agitating the mixture so formed, (ii) introducing into this mixture, at a rate such that the temperature does not exceed about 60°C, one or more aliphatic primary or secondary amines, preferably one or more aliphatic primary monoamines having in the range of 8 to 24 carbon atoms per molecule while agitating the mixture so formed, and (iii) maintaining the temperature of the resultant agitated reaction mixture at between 55 and 60°C until reaction is substantially complete. Another suitable way of producing these amine salts is to concurrently introduce all three of the reactants into the reaction zone at suitable rates and under temperature control such that the temperature does not exceed about 60°C. Component d) Trihydrocarbyl Ester of Dithiophosphoric Acid This group of optional but preferred compounds is composed of O,O-dihydrocarbyl-S-hydrocarbyl thiothionophosphates (also known as O,O-dihydrocarbyl-S-hydrocarbyl phosphorothiothionates) which can be represented by the general formula: wherein each of R 1 , R 2 and R 3 is independently a hydrocarbyl group, especially where R 3 is an alicyclic hydrocarbyl group. Particularly preferred are the O,O-dialkyl-S-hydrocarbyl phosphorothiothionates wherein R 3 is an alicyclic group an R 1 and R 2 are alkyl groups each having up to 18 carbon atoms and most preferably up to 12 carbon atoms. These compounds can be made by various known methods. Probably the most efficacious method involves reacting phosphorus pentasulfide (P 2 S 5 , often regarded as P 4 S 10 ) with the appropriate alcohols or mixture of alcohols. Compounds in which one of the hydrocarbyl groups differs from the other two are preferably made by first reacting the phosphorus pentasulfide with an appropriate alcohol to form an intermediate product, viz. (RO) 2 PSSH, which in turn is reacted with a compound containing at least one reactive olefinic double bond. See in this connection U.S. Pat. Nos. 2,528,732, 2,561,773, 2,665,295, 2,767,206, 2,802,856, 3,023,209, and J. Org. Chem., 1963 , 28, 1262-8.

Other Optional Additive Components The oleaginous fluids and additive concentrates of this invention can and preferably will contain additional components in order to partake of the properties which can be conferred to the overall composition by such additional components. The nature of such components will, to a large extent, be governed by the particular use to which the ultimate oleaginous composition (lubricant or functional fluid) is to be subjected. Some of these other additives are referred to below. A) Supplemental phosphorus-containing antiwear and/or extreme pressure agents. Supplemental metal-free phosphorus-containing antiwear and/or extreme pressure agents can be used in the compositions of this invention, Such compounds are for the most part partially or fully esterified acids of phosphorus, and include for example phosphates, phosphites, phosphonates, phosphonites, and their various sulfur analogs.

All such materials which have been described hereinabove. C) Antioxidants . Most oleaginous compositions will contain a conventional quantity of one or more antioxidants in order to protect the composition from premature degradation in the presence of air, especially at elevated temperatures. Typical antioxidants include hindered phenolic antioxidants, secondary aromatic amine antioxidants, sulfurized phenolic antioxidants, oil-soluble copper compounds, and phosphorus-containing antioxidants. Also useful are methylene-bridged alkylphenols, and these can be used singly or in combinations with each other, or in combinations with sterically-hindered unbridged phenolic compounds. Preferred are mixtures of methylene-bridged alkylphenols such as are described in U.S. Pat. No. 3,211,652. Amine antioxidants, especially oil-soluble aromatic secondary amines can also be used. Although aromatic secondary monoamines are preferred, aromatic secondary polyamines are also suitable. A preferred type of aromatic amine antioxidant is an alkylated diphenylamine of the general formula wherein R 1 is an alkyl group (preferably a branched alkyl group) having 8 to 12 carbon atoms, (more preferably 8 or 9 carbon atoms) and R 2 is a hydrogen atom or an alkyl group (preferably a branched alkyl group) having 8 to 12 carbon atoms, (more preferably 8 or 9 carbon atoms). Most preferably, R 1 and R 2 are the same. One such preferred compound is available commercially as Naugalube 438L, a material which is understood to be predominately a 4,4'-dinonyldiphenylamine (i.e., bis(4-nonylphenyl)amine) wherein the nonyl groups are branched. Another useful type of antioxidant for inclusion in the compositions of this invention is comprised to one or more liquid, partially sulfurized phenolic compounds such as are prepared by reacting sulfur monochloride with a liquid mixture of phenols - at least about 50 weight percent of which mixture of phenols is composed of one or more reactive, hindered phenols - in proportions to provide from 03 to 0.7 gram atoms of sulfur monochloride per mole of reactive, hindered phenol so as to produce a liquid product. Mixtures of different antioxidants can also be used. One suitable mixture is comprised of a combination of (i) an oil-soluble mixture of at least three different sterically-hindered tertiary butylated monohydric phenols which is in the liquid state at 25°C, (ii) an oil-soluble mixture of at least three different sterically-hindered tertiary butylated methylene-bridged polyphenols, and (iii) at least one bis(4-alkylphenyl)amine wherein the alkyl group is a branched alkyl group having 8 to 12 carbon atoms, the proportions of (i), (ii) and (iii) on a weight basis falling in the range of 3.5 to 5.0 parts of component (i) and 0.9 to 12 parts of component (ii) per part by weight of component (iii). D) Rust inhibitors: The compositions of this invention may also contain a suitable quantity of a rust inhibitor. This may be a single compound or a mixture of compounds having the property of inhibiting corrosion of ferrous metal surfaces. Products of this type are currently available from various commercial sources, such as, for example, the dimer and trimer acids sold under the HYSTRENE trademark by the Humco Chemical Division of Witco Chemical Corporation and under the EMPOL trademark by Emery Chemicals. Another useful type of acidic corrosion inhibitors are the half esters of alkenyl succinic acids having 8 to 24 carbon atoms in the alkenyl group with alcohols such as the polyglycols. The corresponding half amides of such alkenyl succinic acids are also usefuL Although added in acidic form, some or all of the carboxylic groups of these carboxylic acid type corrosion inhibitors may be neutralized by excess amine present in the compositions. Other suitable corrosion inhibitors include ether amines; acid phosphates; amines; polyethoxylated compounds such as ethoxylated amines, ethoxylated phenols, and ethoxylated alcohols; and imidazolines. Materials of these types are well known to those skilled in the art and a number of such materials are available as articles of commerce. Other useful corrosion inhibitors are aminosuccinic acids or derivatives thereof represented by the formula: wherein each of R 1 , R 2 , R 5 , R 6 and R 7 is, independently, a hydrogen atom or a hydrocarbyl group containing 1 to 30 carbon atoms, and wherein each of R 3 and R 4 is, independently, a hydrogen atom, a hydrocarbyl group containing 1 to 30 carbon atoms, or an acyl group containing from 1 to 30 carbon atoms. The groups R 1 , R 2 , R 3 , R 4 , R 5 , R 6 and R 7 , when in the form of hydrocarbyl groups, can be, for example, alkyl, cycloalkyl or aromatic containing groups. Preferably R 1 and R 5 are the same or different straight-chain or branched-chain hydrocarbon radicals containing 1-20 carbon atoms. Most preferably, R 1 and R 5 are saturated hydrocarbon radicals containing 3-6 carbon atoms. R 2 , either R 3 or R 4 , R 6 and R 7 , when in the form of hydrocarbyl groups, are preferably the same or different straight-chain or branched-chain saturated hydrocarbon radicals. Preferably a dialkyl ester of an aminosuccinic acid is used in which R 1 and R 5 are the same or different alkyl groups containing 3-6 carbon atoms, R 2 is a hydrogen atom, and either R 3 or R 4 is an alkyl group containing 15-20 carbon atoms or an acyl group which is derived from a saturated or unsaturated carboxylic acid containing 2-10 carbon atoms. Most preferred of the aminosuccinic acid derivatives is a dialkylester of an aminosuccinic acid of the above formula wherein R 1 and R 5 are isobutyl, R 2 is a hydrogen atom, R 3 is octadecyl and/or octadecenyl and R 4 is 3-carboxy-1-oxo-2-propenyl. In such ester R 6 and R 7 are most preferably hydrogen atoms. E) Antifoam agents. Suitable antifoam agents include silicones and organic polymers such as acrylate polymers. Various antifoam agents are described in Foam Control Agents by H. T. Kerner (Noyes Data Corporation, 1976, pages 125-176). Mixtures of silicone-type antifoam agents such as the liquid dialkyl silicone polymers with various other substances are also effective. Typical of such mixtures are silicones mixed with an acrylate polymer, silicones mixed with one or more amines, and silicones mixed with one or more amine carboxylates. F) Friction modifiers. These materials include such substances as the alkyl phosphonates as disclosed in U.S. Pat. No. 4,356,097, aliphatic hydrocarbyl-substituted succinimides derived from ammonia or alkyl monoamines as disclosed in European Patent Publication No. 20037, dimer acid esters as disclosed in U.S. Pat. 4,105,571, and oleamide. Such additives, when used are generally present in amounts of 0.1 to 3 weight percent. Glycerol oleates are another example of fuel economy additives and these are usually present in very small amounts, such as 0.05 to 1 weight percent based on the weight of the formulated oil. Other suitable friction modifiers include aliphatic amines or ethoxylated aliphatic amines, aliphatic fatty acid amides, aliphatic carboxylic acids, aliphatic carboxylic esters, aliphatic carboxylic ester-amides, aliphatic phosphates, aliphatic thiophosphonates, aliphatic thiophosphates, etc., wherein the aliphatic group usually contains above about eight carbon atoms so as to render the compound suitably oil soluble. A desirable friction modifier additive combination which may be used in the practice of this invention is described in European Patent Publication No. 389,237. This combination involves use of a long chain succinimide derivative and a long chain amide. G) Seal swell agents. Additives may be introduced into the compositions of this invention in order to improve the seal performance (elastomer compatibility) of the compositions. Known materials of this type include dialkyl diesters such as dioctyl sebacate, aromatic hydrocarbons of suitable viscosity such as Panasol AN-3N, products such as Lubrizol 730, polyol esters such as Emery 2935, 2936, and 2939 esters from the Emery Group of Henkel Corp. and Hatcol 2352, 2962, 2925, 2938, 2939, 2970, 3178, and 4322 polyol esters from Hatco Corp. Generally speaking the most suitable diesters include the adipates, azelates, and sebacates of C 8 -C 13 alkanols (or mixtures thereof), and the phthalates of C 4 -C 13 alkanols (or mixtures thereof). Mixtures of two or more different types of diesters (e.g., dialkyl adipates and dialkyl azelates, etc) can also be used. Examples of such materials include the n-octyl, 2-ethylhexyl, isodecyl, and tridecyl diesters of adipic acid, azelaic acid, and sebacic acid, and the n-butyl, isobutyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, and tridecyl diesters of phthalic acid. H) Viscosity index improvers. Depending upon the viscosity grade required, the lubricant compositions can contain one or more viscosity index improvers (polymeric materials which are often supplied in the form of a solution in a solvent or carrier fluid). Among the numerous types of materials known for such use are hydrocarbon polymers grafted with, for example, nitrogen-containing polymers, olefin polymers such as polybutene, ethylene-propylene copolymers, hydrogenated polymers and copolymers and terpolymers of styrene with isoprene and/or butadiene, polymers of alkyl acrylates or alkyl methacrylates, copolymers of alkyl methacrylates with N-vinyl pyrrolidone or dimethylaminoalkyl methacrylate; post-grafted polymers of ethylene-propylene with an active monomer such as maleic anhydride which may be further reacted with an alcohol or an alkylene polyamine; and styrene/maleic anhydride polymers post-treated with alcohols and/or amines. Dispersant viscosity index improvers, which combine the activity of dispersants and viscosity index improvers, suitable for use in the compositions of this invention are described, for example, in U.S. Pat Nos. 3,702,300; 4,068,056; 4,068,058; 4,089,794; 4,137,185; 4,146,489; 4,149,984; 4,160,739; and 4,519,929. I) Pour point depressants. Another useful type of additive which can be included in compositions of this invention is one or more pour point depressants. The use of pour point depressants in oil-base compositions to improve the low temperature properties of the compositions is well known to the art See, for example, the books Lubricant Additives by C. V. Smalheer and R. Kennedy Smith (Lezius-Hiles Co. Publishers, Cleveland, Ohio, 1967); Gear and Transmission Lubricants by C. T. Boner (Reinhold Publishing Corp., New York, 1964); and Lubricant Additives by M. W. Ranney (Noyes Data Corporation, New Jersey, 1973). Among the types of compounds which function satisfactorily as pour point depressants in the compositions of this invention are polymethacrylates, polyacrylates, condensation products of haloparaffin waxes and aromatic compounds, and vinyl carboxylate polymers. Also useful as pour point depressants are terpolymers made by polymerizing a dialkyl fumarate, vinyl ester of a fatty acid and a vinyl alkyl ether. Techniques for preparing such polymers and their uses are disclosed in U.S. Pat. No. 3,250,715. J) Other metal corrosion inhibitors . In order to protect such metals as lead, cadmium, aluminum, magnesium, silver, zinc and alloys thereof etc., special corrosion inhibitors can be used. These include such substances as gallic acid esters, and phthalic acid esters. The above description of other additives which can be used in the compositions of this invention is not to be construed as limitive, as many other types of additives can be used in such compositions. The only requirements are that such other additives not excessively interfere with the performance of the compositions of this invention and that they exhibit suitable compatibility with the additives otherwise being employed therein. K) Free Amine. The free amines which can be employed in the compositions of this invention can be any of the amines referred to above in connection with the amine salts of partial esters of phosphoric acid or thiophosphoric acids or in connection with the amine salts of carboxylic acids, provided that the amines are oil-soluble. Of the various amines, the preferred type is composed of alkyl primary monoamines, and alkenyl primary monoamines, especially those containing from 6 to 24 carbon atoms. Examples of such amines include hexylamine, octylamine, nonylamine, decylamine, undecylamine, dodecylamine, tridecylamine, tetradecylamine, pentadecylamine, hexadecylamine, heptadecylamine, octadecylamine, eicosylamine, docosylamine, tetracosylamine, oleylamine, cocoamine, soyamine, C 12-14 tertiary alkyl primary amine, and C 22-24 tertiary alkyl primary amine. Generally speaking, the free amine used in the compositions will correspond to the amine used in forming either the amine salt of the phosphorus acid or the amine salt of the carboxylic acid, or both. The term "free amine" refers to the form of the amine as it is charged into the blender or mixing vessel in which the additive concentrate or the lubricating oil or functional fluid composition is being formed. Some or all of the free amine may complex with or react with other components being used in the product being formed, such as acidic additive components. Thus the term "free amine" does not signify or imply that the amine must remain free -- all or part of it may remain uncomplexed and unreacted, but this is not a requirement Base oils The additive combinations of this invention can be incorporated in a wide variety of lubricants and functional fluids in effective amounts to provide suitable active ingredient concentrations. The base oils not only can be hydrocarbon oils of lubricating viscosity derived from petroleum (or tar sands, coal, shale, etc.), but also can be natural oils of suitable viscosities such as rapeseed oil, etc., and synthetic oils such as hydrogenated polyolefin oils; poly-α-olefins (e.g., hydrogenated or unhydrogenated α-olefin oligomers such as hydrogenated poly-1-decene); alkyl esters of dicarboxylic acids; complex esters of dicarboxylic acid, polyglycol and alcohol; alkyl esters of carbonic or phosphoric acids; polysilicones; fluorohydrocarbon oils; and mixtures of mineral natural and/or synthetic oils in any proportion, etc. The term "base oil" for this disclosure includes all the foregoing. The additive combinations of this invention can thus be used in lubricating oil and functional fluid compositions, such as automotive crankcase lubricating oils, automatic transmission fluids, gear oils, hydraulic oils, cutting oils, etc., in which the base oil of lubricating viscosity is a mineral oil, a synthetic oil, a natural oil such as a vegetable oil, or a mixture thereof, e.g., a mixture of a mineral oil and a synthetic oil. Examples of such are known in the art. The fact that the base oils used in the compositions of this invention may be composed of (i) one or more mineral oils, (ii) one or more synthetic oils, (iii) one or more natural oils, or (iv) a blend of (i) and (ii), or (i) and (iii), or (ii) and (iii), or (i), (ii) and (iii) does not mean that these various types of oils are necessarily equivalents of each other. Certain types of base oils may be used in certain compositions for the specific properties they possess such as high temperature stability, non-flammability or lack of corrosivity towards specific metals (e.g., silver or cadmium). In other compositions, other types of base oils may be preferred for reasons of availability or low cost Thus, the skilled artisan will recognize that while the various types of base oils discussed above may be used in the compositions of this invention, they are not necessarily functional equivalents of each other in every instance. Proportions and Concentrations In general, the components of the additive compositions of this invention are employed in the oleaginous liquids (e.g., lubricating oils and functional fluids) in minor amounts sufficient to improve the performance characteristics and properties of the base oil or fluid. When employing free amine, the amount employed is most preferably the amount sufficient to render the pH (determined as described hereinafter) of the finished additive concentrate as formed within the range of 4 to 9. The amounts of the other components will vary in accordance with such factors as the viscosity characteristics of the base oil or fluid employed, the viscosity characteristics desired in the finished product, the service conditions for which the finished product is intended, and the performance characteristics desired in the finished product. However, generally speaking, when using component a-1) or a-3), the following concentrations (weight percent) of the components (active ingredients) in the base oils or fluids are illustrative: Typical Range Preferred Range P- & B-contg dispersant 1 - 7 2 - 5 S-contg antiwear/E.P. agent 2 - 6 3 - 4 Amine salt of P-contg acid-ester 0 - 3 0 - 2 Trihydrocarbyl dithiophosphate 0 - 3 0 - 2 Amine salt of carboxylic acid 0 - 1 0.01 - 2 Demulsifier 0 - 1 0 - 0.2 Cu corrosion inhibitor 0 - 0.5 0.01 - 0.2 Supplemental P-antiwear/E.P. agent 0 - 0.7 0.05 - 0.4 Supplemental ashless dispersant 0 - 3 0 - 2 Antioxidant 0 - 2 0 - 1 Rust inhibitor 0 - 2 0.02 - 1 Antifoam agent 0 - 0.3 0.0002 - 0.1 Friction modifier 0 - 3 0 - 1 Seal swell agent 0 - 20 0 -10 Viscosity index improver 0 - 20 0 - 15 Pour point depressant 0 - 2 0 - 1 Other metal corrosion inhibitors 0 - 1 0 - 0.5 Free amine 0 - 2 0.3 - 1 Likewise, generally speaking, when using component a-2) or a-4), the following concentrations (weight percent) of the components (active ingredients) in the base oils or fluids are illustrative: Typical Range Preferred Range P-contg dispersant 1 - 7 2 - 5 S-contg antiwear/E.P. agent 2 - 6 3 - 4 Amine salt of P-contg acid-ester 0 - 3 0 - 2 Trihydrocarbyl dithiophosphate 0 - 3 0 - 2 Amine salt of carboxylic acid 0 - 1 0.01 - 2 Demulsifier 0 - 1 0 - 0.2 Cu corrosion inhibitor 0 - 0.5 0.01 - 0.2 B-contg additive 0 - 5 0 - 2 Supplemental P-antiwear/E.P. agent 0 - 0.7 0.05 - 0.4 Supplemental ashless dispersant 0 - 3 0 - 2 Antioxidant 0 - 2 0 - 1 Rust inhibitor 0 - 2 0.02 - 1 Antifoam agent 0 - 0.3 0.0002 - 0.1 Friction modifier 0 - 3 0 - 1 Seal swell agent 0 - 20 0 - 10 Viscosity index improver 0 - 20 0 - 15 Pour point depressant 0 - 2 0 - 1 Other metal corrosion inhibitors 0 - 1 0 - 0.5 Free amine 0 - 2 0.3 - 1 The individual components can be separately blended into the base oil or fluid or can be blended therein in various subcombinations, if desired. Moreover, such components can be blended in the form of separate solutions in a diluent Except for viscosity index improvers and/or pour point depressants (which in many instances are blended apart from other components), it is preferable to blend the other selected components into the base oil by use of an additive concentrate of this invention, as this simplifies the blending operations, reduces the likelihood of blending errors, and takes advantage of the compatibility and solubility characteristics afforded by the overall concentrate. The additive concentrates of this invention will contain the individual components in amounts proportioned to yield finished oil or fluid blends consistent with the concentrations tabulated above. In most cases, the additive concentrate will contain one or more diluents such as light mineral oils, to facilitate handling and blending of the concentrate. Thus concentrates containing up to 50% by weight of one or more diluents or solvents can be used. The oleaginous liquids provided by this invention can be used in a variety of applications. For example, they can be employed as crankcase lubricants, gear oils, hydraulic fluids, manual transmission fluids, automatic transmission fluids, cutting and machining fluids, brake fluids, shock absorber fluids, heat transfer fluids, quenching oils, and transformer oils. The compositions are particularly suitable for use as automotive and industrial gear oils. Blending The formulation or blending operations are relatively simple and involve mixing together in a suitable container or vessel, using a dry, inert atmosphere where necessary or desirable, appropriate proportions of the selected ingredients. Those skilled in the art are cognizant of and familiar with the procedures suitable for formulating and blending additive concentrates and lubricant compositions. Usually the order of addition of components to the blending tank or vessel is not critical provided of course, that the components being blended at any given time are not incompatible or excessively reactive with each other. Agitation such as with mechanical stirring equipment is desirable to facilitate the blending operation. Frequently it is helpful to apply sufficient heat to the blending vessel during or after the introduction of the ingredients thereto, so as to maintain the temperature at, say, 40-60°C, and preferably no higher than about 60°C. Similarly, it is sometimes helpful to preheat highly viscous components to a suitable temperature even before they are introduced into the blending vessel in order to render them more fluid and thereby facilitate their introduction into the blending vessel and render the resultant mixture easier to stir or blend. Naturally the temperatures used during the blending operations should be controlled so as not to cause any significant amount of thermal degradation or unwanted chemical interactions. When forming the lubricant compositions of this invention, it is usually desirable to introduce the additive ingredients into the base oil with stirring and application of mildly elevated temperatures, as this facilitates the dissolution of the components in the oil and achievement of product uniformity. The following examples illustrate preferred additive concentrates and oleaginous compositions containing such concentrates. These examples are not intended to limit, and should not be construed as limiting, this invention.

EXAMPLE XVII The effectiveness of the compositions of this invention was illustrated in several standard L-37 and L42 tests. In one set of L-37 and L-42 tests, the composition was prepared by blending together the following components in which the proportions are by weight: Phosphorylated ashless dispersant 4.00% Sulfurized isobutylene 3.50% Exxon 1365 mineral oil 28.68% Exxon 2507 mineral oil (Bright Stock) 63.82% The phosphorylated ashless dispersant was formed from a polyisobutenyl succinimide, viz., HiTEC® 646 additive (Ethyl Petroleum Additives, Inc.; Ethyl Petroleum Additives, Ltd.; Ethyl S.A.; Ethyl Canada Ltd.). Phosphorylation was accomplished in the manner of Example 5 using 2.7 parts by weight of HiTEC® 646 additive, 0.3 parts by weight of solid phosphorous acid (H 3 PO 3 ), and 1 part by weight of process oil diluent The sulfurized isobutylene was HiTEC® 309 sulfurized isobutylene additive; (Ethyl Petroleum Additives, Inc.; Ethyl Petroleum Additives, Ltd.; Ethyl S.A.; Ethyl Canada Ltd.). This oil blend had kinematic viscosity at of 153.98 cSt at 40°C, and 16.63 cSt at 100°C. The results in terms of numerical ratings of the L-37 test were as follows: Description Ring Pinion Ridging 0.00 0.00 Rippling 0.00 0.01 Spalling 0.00 0.00 Wear 0.01 0.01 Pitting 0.01 0.01 Scoring 0.00 0.00 The above numerical scale is as follows: None = 0.00 Trace = 0.01 Light = 0.50 Medium = 5.00 Heavy = 10.00 The Ring-Gear Drive Side Inspection after completion of a High-Speed, Low Torque 100-minute run, was rated Satisfactory. The Pinion-Drive Side and Ring-Gear Drive Side Inspection after the complete test resulted in the following Gear-tooth surface condition ratings: Inspection before and after the complete test resulted in the following Backlash measurements: Initial 0.004 cm After test 0.005 cm After the test the axle shafts, axle housing, carrier housing, pinion assembly, ring-gear assembly and differential assembly were rated in Good condition, the bearings (races) and differential pins showed Light discoloration and the bearings (rollers) showed Light discoloration with a Trace of corrosion. In the L-42 test, the Sequence 3 inspection showed no scoring on either the drive side or the coast side of the ring gear. The end of test inpection gave the following results: Ring Gear, Drive Side 4% scored Ring Gear, Coast Side 6% scored Pinion Gear, Drive Side 5% scored Pinion Gear, Coast Side 8% scored Another L-42 test was conducted using the same oil composition as above except that the sulfurized isobutylene was replaced by an equal amount of a di-tert-butyl polysufide composed mainly of the trisulfide. In this L-42 test, the Sequence 3 inspection showed no scoring on either the drive side or the coast side of the ring gear, and the end of test inpection showed the following: Ring Gear, Drive Side No Scoring Ring Gear, Coast Side 10% scored Pinion Gear, Drive Side No Scoring Pinion Gear, Coast Side 13% scored These results are considered a pass, and actually are better than the results achieved with a passing reference oil. The procedure used in determining pH of preferred additive concentrates of this invention involves diluting the sample of the composition in a mixture of methanol and toluene and then assaying "non-aqueous" pH with a conventional pH probe as used in aqueous systems. Copper corrosion ratings for the purposes of this invention are conducted using the standard ASTM D-130 procedure modified to the extent that the additive concentrate to be tested is first stored in an oven for 120 hours at 65°C. Then the concentrate is blended into the test oil to the selected test concentration and the test is conducted at 121°C. As used in the foregoing description, the term "oil-soluble" is used in the sense that the component in question has sufficient solubility in the selected base oil in order to dissolve therein at ordinary temperatures to a concentration at least equivalent to the minimum concentration specified herein for use of such component Preferably, however, the solubility of such component in the selected base oil will be in excess of such minimum concentration, although there is no requirement that the component be soluble in the base oil in all proportions. As is well known to those skilled in the art, certain useful additives do not completely dissolve in base oils but rather are used in the form of stable suspensions or dispersions. Additives of this type can be employed in the compositions of this invention, provided they do not significantly interfere with the performance or usefulness of the composition in which they are employed. Reference may also be made to EP-A- 053100.
