Abstract (en)
[origin: WO2016158971A1] The present invention provides a lubricant oil composition having an excellent friction reduction effect and excellent fuel saving properties. Provided is a lubricant oil composition comprising (A) a lubricant-oil base oil, (B) a molybdenum compound, and (C) an ashless friction modifier, wherein said (B) molybdenum compound contains a binuclear organic molybdenum compound represented by formula (I), the content of the binuclear organic molybdenum compound in terms of molybdenum atoms being 0.030-0.140 mass%, inclusive, on the basis of the total amount of the lubricant oil composition; as said (C) ashless friction modifier, (C1) an ester ashless friction modifier and/or (C2) an amine ashless friction modifier is contained; and the total of the contents of said (C1) ester ashless friction modifier and said (C2) amine ashless friction modifier exceeds 0.1 mass% but is not more than 1.8 mass% on the basis of the total amount of the lubricant oil composition. (I) (In formula (I), R1 to R4 each represent a hydrocarbon group having a carbon number of 4-22, and R1 to R4 may be identical or different. X1 to X4 each represent a sulfur atom or an oxygen atom.)
