Friction reducing lubricating oil composition

摘要

A lubricating oil composition which includes partial esters of glycerol substantially free from glycerol are disclosed. The partial esters of glycerol are present in an amount of about 0.05 to about one percent by weight, and include less than about 1 weight percent of unreacted glycerol based on the total weight of glycerol esters and free glycerol present. Enhanced reduction in friction and improved stability are obtained.
