The present application provides a lubricating oil composition comprising: a lubricating oil base oil; (A) a triazole-based metal deactivator in an amount of 0.005 to 0.03 mass % in terms of nitrogen content based on the total amount of the composition; and a combination of The succinimide compound represented by the following general formula (1) is (B1) 0.0005 to 0.02 mass % based on the total amount of nitrogen. (In the general formula (1), R 1 and R 2 each independently represent a hydrogen atom or a linear or branched alkyl or alkenyl group having 1 to 36 carbon atoms, and at least one of R 1 and R 2 is A linear or branched alkyl or alkenyl group having 8 to 36 carbon atoms, and n represents an integer of 1 to 10). |
