Disclosed are friction modifier compositions and a method of lubricating an internal combustion engine, comprising supplying to said engine an oil of lubricating viscosity and from 0.25 to 5 weight percent based upon the total mass of the lubricating oil composition of a friction modifier composition containing: a) an amino alcohol reaction product prepared by isomerizing a C12-C30 normal alpha olefin using at least one of a solid or liquid catalyst to form an internal olefin; epoxidizing said olefin; and reacting with a mono-hydroxyl amine; b) an ester of glycerol and a C12-C22 carboxylic acid containing 0 to 3 double bonds. |
