<p><P>PROBLEM TO BE SOLVED: To provide a lubricating oil additive which is effective as a friction reducing agent or anti-wear agent and, in particular, not only when a sliding surface is a metal such as steel but also when the sliding surface is a diamond-like carbon film, includes a superior friction reduction effect, to provide a lubricating oil composition having a superior friction reduction effect, being prepared by compounding the lubricating oil additive, and to provide a low friction sliding member of which the sliding surface of sliding in the existence of the lubricating oil composition has a diamond-like carbon film. <P>SOLUTION: The lubricating oil additive includes at least one of compound selected from amino phosphorus compound such as mono-N-(alkyl)phosphoric amide and di-N-(alkyl)thiophosphoric diamide and its derivative. The lubricating oil composition is made by compounding the lubricating oil additive. The low friction sliding member of which the sliding surface of sliding in the existence of the lubricating oil composition icnludes the diamond-like carbon film is also provided. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
