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 improving fuel efficiency in an engine by using as the engine oil a lubricating oil formulation containing one or more of the CCSV-boosting base stocks and/or cobase stocks.

Claim (Index 1):
A method for determining boosting efficacy of a first base stock in boosting the cold crank simulator viscosity at a given temperature as determined pursuant to ASTM D5293 (\u201cCCSV\u201d) of a lubricating oil formulation comprising the first base stock and a reference oil, the method comprising:\n determining the kinematic viscosity at 100\u00b0 C. as determined pursuant to ASTM D2245 (\u201cKV100\u201d) of the reference oil; determining the CCSV of the reference oil; determining the KV100 of a mixture oil consisting of the first base stock and the reference oil at a first concentration of the first base stock based on wthe total quantity of the mixture oil; determining the CCSV of the mixture oil; and determining the first base stock as not a CCSV-boosting base stock if the CCSV of the mixture oil is smaller than the CCSV of the reference oil.
