ADDITIVE FOR LUBRICATING OILS AND LUBRICATING OIL COMPOSITION

摘要

The present invention provides: a lubricant additive containing (A) a nitrogen-containing compound represented by the general formula (1) and (B) a borate ester compound represented by the general formula (2) and/or a borate ester compound represented by the general formula (3); and a lubricant oil composition containing the lubricant additive and a lubricant base oil, the lubricant additive and the lubricant oil composition containing an oiliness agent-type friction modifier that can exhibit a better friction reduction effect than that of conventional oiliness agent-type friction modifiers under a wider range of friction conditions.
