A crankcase engine lubricant which comprises the add mixture of the following components: (A) a lubricating oil which comprises the add mixture of the following components: a complex alcohol ester basestock and at least one additional basestock; and (B) an additive package; wherein the crankcase engine lubricant exhibits a percent fuel economy improvement in the range between about 0.3 to 5.0%, versus the lubricating oil without the complex alcohol ester basestock.

Engine oil lubricants formed from complex alcohol esters

A synthetic ester composition which exhibits thermal and oxidative stability, lower friction coefficient and lower wear, wherein the ester composition comprises the reaction product of: a branched or linear alcohol having the general formula R(OH).sub.n, wherein R is an aliphatic or cyclo-aliphatic group having from about 2 to 20 carbon atoms and n is at least 2; and at least one branched mono-carboxylic acid which has a carbon number in the range between about C.sub.5 to C.sub.13 ; wherein the synthetic ester composition has between about 5-35% unconverted hydroxyl groups, based on the total amount of hydroxyl groups in the branched or linear alcohol.
