(57) [Summary] [Constitution] Based on the total weight of the composition, based on the lubricating base oil, (A) General formula (R 1 and R 2 are C 2-25 alkyl group, aryl group or alkylaryl group, R 3 is C 2-4 alkylene group or alkyleneaminoalkylene group, and n is 1 or 2). 0.1 to 2.0% by weight of an alkanolamine complex and (B) the general formula: (R 4 and R 5 are C 1-20 alkyl, aryl or alkylaryl groups) MoDTC 0.01-1 A lubricating oil composition containing 0% by weight. [Effect] In addition to being excellent in wear resistance, it provides a low friction coefficient particularly under low-speed rotation and low-load operating conditions, and is suitable as a lubricating oil for internal combustion engines of automobiles. |
