Abstract:
This disclosure relates to cold cranking simulator viscosity (“CCSV”) boosting base stocks that allow flexibility for engine oil formulations to meet both high and low temperature viscosity requirements while maximizing fuel efficiency. The CCSV-boosting base stocks can include C28-C60 hydrocarbon materials, linear esters, tertiary amides, dialkyl carbonates, aromatic alcohols, and aromatic ethers. This disclosure also relates to lubricating oil formulations containing the CCSV-boosting base stocks, and a method for determining the CCSV-boosting efficacy of a base stock.

Claim (Index 20):
A lubricating oil base stock having a KV100 in the range from 3.0 to 12.0 cSt, a NV of no higher than 20%, and the following properties:\n when blended with a reference oil which is a Group IV base stock having a KV100 of 4.0 cSt to form a mixture oil comprising the co-base stock at a concentration of 10 wt %, based on the total weight of the mixture oil, the mixture oil exhibits at least one of the following (i) and (ii): (i) a viscosity measured at 0.1 s \u22121  shear rate at a temperature T1\u00b0 C. of v(T1) Pa\u00b7s, a viscosity measured at 0.1 s \u22121  shear rate at the temperature T2\u00b0 C. of v(T2) Pa\u00b7s, where \u221235\u2264T1\u226425, 0<T1\u2212T2\u226410, v1(T2)/v1(T1)\u226550; and (ii) a peak in the vicinity of the temperature of T1\u22125\u00b0 C. on the DSC curve thereof in the temperature range from \u221260\u00b0 C. to 25\u00b0 C. when the mixture oil is being cooled down.
