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 engine oil a lubricating oil formulation containing one or more of the CCSV-boosting base stocks.

Claim (Index 23):
A lubricant base stock comprising at least one of the following:\n a C28-C60 hydrocarbon material having a carbon backbone comprising on average 25 to 50 carbon atoms and on average no more than 5 branches attached to the carbon backbone per molecule; a linear ester having the following formula R 1 \u2014C(O)\u2014O\u2014R 2 , where R 1  and R 2  are independently each a linear hydrocarbyl group comprising from 4 to 30 carbon atoms, and R 1  and R 2  taken together comprise, in total, no more than 40 carbon atoms; a tertiary amide having the following formula: wherein R 3  is a linear C14-C20 alkyl group; and R 4  and R 5  are, independently, each a linear C1-C20 alkyl group; a dialkyl carbonate having the following formula: wherein R 6  and R 7  are, independently, each a linear C1-C40 alkyl group, and R 6  and R 7  taken together comprise, in total, from 20 to 40 carbon atoms; an aromatic alcohol having the following formula: wherein ring A is an aromatic ring structure, the hydroxyl group is connected directly to a carbon atom in the aromatic ring structure in ring A, R 9  is a C8-C30 alkyl having a C7-C29 carbon backbone and no more than five branches connected to the carbon backbone; and m is 1, 2, or 3; an aromatic ether having the following formula: wherein ring A\u2032 is an aromatic ring structure, the \u2014O\u2014 group is connected directly to a carbon atom in the aromatic ring structure in ring A\u2032, R 11 , the same or different at each occurrence, independently is a C1-C30 alkyl group having a C1-C30 carbon backbone and on average no more than five branches connected to the carbon backbone in each R 11 ; m is 0, 1, 2, or 3, and R 12  is a C1-C30 alkyl group having a C1-C30 carbon backbone and no more than five branches connected to the carbon backbone; and mixtures and combinations thereof.
