Abstract: Through a lubricating oil additive including an amide compound represented by the following general formula (1) and a lubricating oil composition using the same, a lubricating oil additive and a lubricating oil composition exhibiting not only a high intermetal friction coefficient but also excellent intermetal friction-coefficient/slipping-velocity characteristics are provided. Ra—CO—(NH-L1)n-NRbRc   (1) In the formula, Ra is a straight-chain alkyl group having 8 to 22 carbon atoms or a branched-chain alkyl group having 8 to 22 carbon atoms, or a straight-chain alkenyl group having 8 to 22 carbon atoms or a branched-chain alkenyl group having 8 to 22 carbon atoms; L1 is an alkylene group having 1 to 6 carbon atoms; n is an integer of 1 to 4; and —NRbRc is a primary amino group or a piperazyl group.
