[PROBLEMS] To have a long oxidation life under high temperature conditions, Provided is a lubricating oil composition for an internal combustion engine having excellent fuel economy performance. The kinematic viscosity at 100 ° C. is 2 to 12 mm. 2 / s, a mineral oil or a synthetic oil having a% CA of 6 or less as determined by ring analysis (ndm method) as a base oil, wherein (a) zinc dithiophosphate, (b) succinimide, A molybdenum complex obtained by reacting a molybdenum trioxide with a basic nitrogen compound selected from the group consisting of a carboxylic acid amide and a Mannich base, an oil-soluble sulfur-containing molybdenum complex obtained by further reacting with sulfur or thioacetamide, And (c) a lubricating oil composition for an internal combustion engine, comprising at least one selected from molybdenum dithiocarbamate, molybdenum dithiophosphate and an amine salt of molybdic acid. |
