Abstract (en)

A lubricating oil composition which exhibits an excellent friction-reducing effect and excellent fuel consumption reducing properties is provided. The lubricating oil composition includes a lubricating base oil (A), a molybdenum compound (B), and an ashless friction modifier (C), wherein the lubricating oil composition includes a binuclear organic molybdenum compound represented by the following general formula (I) as the molybdenum compound (B), with the content of the binuclear organic molybdenum compound as converted into molybdenum atoms being 0.030 mass% or more and 0.140 mass% or less based on the total amount of the lubricating oil composition; and an ester-based ashless friction modifier (C1) and/or an amine-based ashless friction modifier (C2) as the ashless friction modifier (C), with the total content of the ester-based ashless friction modifier (C1) and the amine-based ashless friction modifier (C2) being more than 0.1 mass% and 1.8 mass% or less based on the total amount of the lubricating oil composition: in the general formula (I), R 1 to R 4 each represents a hydrocarbon group having 4 to 22 carbon atoms, R 1 to R 4 may be the same as or different from each other, and X 1 to X 4 each represents a sulfur atom or an oxygen atom.
