ABSTRACT:
Provided is a lubricating oil composition comprising a base oil for a lubricating oil, (A) a fatty acid partial ester compound, 0.5 to 1.5% by mass of (B) (b1) an aliphatic amine compound and/or (b2) an acid amide compound, 0.01 to 0.1% by mass of (C) a specific benzotriazole derivative and a specific amount of (D) a specific succinimide compound. It is a lubricating oil composition of an environmental regulation compliant type which is used for internal combustion engines such as gasoline engines, diesel engines, engines using dimethyl ether for fuel, gas engines and the like, which does not contain Mo base friction reducing agents and is reduced in ash, phosphorus and sulfur and in which a friction reducing effect, an oxidation stability and a corrosion inhibiting effect are enhanced.
