    摘要: The present invention provides for a lubricant oil composition for internal combustion engines for automobiles with enhanced friction loss reduction and is especially suitable for a pressure-accumulating (common rail) type diesel engine equipped with an EGR system. The lubricant oil composition contains a base oil composed of a mineral and/or synthetic oil incorporated with at least four additives of (A) at least one type of organomolybdenum compound selected from the group consisting of sulfurized oxymolybdenum dithiocarbamate, sulfurized oxymolybdenum dithiophosphate, molybdenum phosphate and molybdenum-amine complex at 0.01 to 0.20 wt. % as Mo, (B) zinc dialkyl dithiophosphate at 0.01 to 0.50 wt. % as P, (C) one of Ca and Mg salts of alkyl salicylate at 0.05 to 1.0 wt. % as Ca or Mg and (D) Zn salt of alkyl salicylate at 0.005 to 0.2 wt. % as Zn, all percentages being based on the whole composition, especially suitable for a pressure-accumulating (common rail) type diesel engine equipped with an exhaust gas recirculation (EGR) system.
