More Information
Summary:A lubricating oil composition comprising a base oil for a lubricating oil and the following components (A) to (D) contained in the base oil: (A) a fatty acid partial ester compound; (B) (b1) an aliphatic amine compound and/or (b2) an acid amide compound in an amount of 0.5 to 1.5% by mass; (C) a specific benzotriazole derivative in an amount of 0.01 to 0.1% by mass; and (D) a specific succinic acid imide compound in a specified amount. The lubricating oil composition can be used in an internal combustion engine such as a gasoline engine, a diesel engine, an engine utilizing dimethyl ether as a fuel or a gas engine, contains no Mo-based friction reducing agent, is reduced in ash content, phosphorus content and sulfur content, is improved in friction-reducing properties, oxidation stability and a corrosion-preventing activity, and meets the environmental regulations.
