Abstract (en)

[origin: EP2716743A1] The present invention provides a lubricating oil composition exhibit excellent friction reduction properties with a small amount of molybdenum. The lubricating oil composition comprises a lubricating base oil, (A) a phosphoric acid ester metal salt represented by formula (1) and (B) an organic molybdenum compound with a ratio of molybdenum to sulfur of 1 : 3.5 or greater. (In formula 1, R 1 to R 4 are each a hydrocarbon group having 1 to 30 carbon atoms, an alkyl or alkenyl group having 1 to 30 carbon atoms, or an alkylthioethyl comprising an alkyl group having 1 to 30 carbon atoms and may be the same or different from each other; X 1 , X 2 , X 3 and X 4 are each sulfur or oxygen, either X 1 or X 2 is oxygen or both are oxygen, and either X 3 or X 4 is oxygen or both are oxygen; and Y is a metal element.)
