LUBRICANT OIL COMPOSITION FOR INTERNAL COMBUSTION ENGINES

WIPO Patent Application WO/2017/170769

A1

The present invention minimizes negative effects on an exhaust gas purification device and achieves excellent energy efficiency while inhibiting an increase in viscosity of a lubricant oil when biofuel gets mixed therein, by using a lubricant oil composition for internal combustion engines, which comprises: a base oil; (A) at least one component selected from (A1) alkenyl or alkyl succinic acid monoimide and boron derivatives thereof and (A2) alkenyl or alkyl succinic acid bisimide and boron derivatives thereof; (B) at least one component selected from binuclear and trinuclear organomolybdenum compounds; (C) superbasic sodium sulfonate; and (D) at least one component selected from superbasic calcium salicylate (D1) and superbasic calcium phenate (D2), wherein the contained amounts of components (A) to (C) and the contained amount ratio between component (A1) and component (A2) are respectively specified to fall within prescribed ranges, while the contained amount of sulfuric acid ash is specified to be 0.8 mass% or less.
