Abstract

A lubricating oil composition for internal combustion engines comprising a base oil of lubricating viscosity having a kinematic viscosity of 22 to 300 mm2/s at 40°C, an overbased alkyloxybenzenesulfonate detergent, a neutral or basic salicylate detergent, an ashless dispersant, a zinc dialkyldithiophosphate, and a nonmetallic oxidation inhibitor.
The lubricating oil composition of the present invention has enough stability against thermal oxidation and enough detergency at elevated temperatures to comply with the severe operating conditions required for modern diesel engines and to satisfactorily lubricate the engine even under severe friction conditions.
