More Information
Summary: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, R1 to R4 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; X1, X2, X3 and X4 are each sulfur or oxygen, either X1 or X2 is oxygen or both are oxygen, and either X3 or X4 is oxygen or both are oxygen; and Y is a metal element.)
