Abstract:
This disclosure relates to cold cranking simulator viscosity (“CCSV”) reducing base stocks that allow flexibility for low viscosity SAE engine oil grades (e.g., 5 W and 0 W) to meet demanding low temperature viscosity requirements while maintaining a higher base oil viscosity for improved wear protection. The CCSV-reducing base stocks include mono-esters derivable from a Guerbet alcohol and a monocarboxylic acid. The disclosure also relates to lubricating oil formulations containing the CCSV-reducing base stocks, and a method for determining the CCSV-reducing efficacy of a base stock.

Claim (Index 15):
A method for making a lubricating oil formulation, comprising:\n providing a reference oil with a kinematic viscosity at 100\u00b0 C. as determined by ASTM D2245 (\u201cKV100\u201d) of KV100(ref) and cold crank simulator viscosity at a given temperature as determined by ASTM 5293 (\u201cCCSV\u201d) of CCSV(ref); providing a first base stock having a CCSV of CCSV(b), where CCSV(b)<CCSV(ref); such that when mixing the reference oil and the first base stock to obtain a mixture oil having a KV100 of KV100(oil) and a CCSV of CCSV(oil), one of the conditions (i) and (ii) below is met: (i) D(kv)>0 and D(ccsv)<\u22125; and (ii) D(kv)<0, D(ccsv)<\u22125, and D(ccsv)/D(kv)\u22653.0, where D \ue8a0 ( kv ) = KV \ue89e \ue89e 100 \ue89e ( oil ) - KV \ue89e \ue89e 100 \ue89e \ue89e ( ref ) KV \ue89e \ue89e 100 \ue89e ( ref ) \u00d7 100 ; and D \ue8a0 ( ccsv ) = CCSV \ue89e \ue89e ( oil ) - CCSV \ue89e \ue89e ( ref ) CCSV \ue8a0 ( ref ) \u00d7 100.
