(57) [Summary] [Structure] Based on the total weight of the composition with respect to the base oil, (A) General formula (R 1 and R 2 are C 4 alkyl group or alkenyl group of ~ 18, p and q are positive integers such that their sum is 4) 1 to 10% by weight of sulfurized oxymolybdenum organophosphorodithioate represented by: (B) 3 to 15% by weight of sulfurized olefin or alkyl sulfur and (C) alkylamine of phosphoric acid ester, phosphorous acid ester or phosphoric acid ester Salt 0. A lubricating oil composition for final reduction gears, containing 1 to 5% by weight. [Effect] Compared with the conventional compound containing the SP additive, the transmission efficiency of the differential gear under each condition such as input torque, input speed, oil temperature, etc. is further improved, improving fuel efficiency.
