A low friction sliding material and lubricating oil composition using the sliding mechanism of the lubricating oil composition

The present invention can provide a composition comprising at least having any nitrogen (N) atoms and oxygen (O) atoms in a molecule, containing or not containing sulfur (S) atom of the organic molybdenum compound, the organic molybdenum sulfur compound as a reference compound content of 0.5 mass% or less of the lubricating oil composition, the lubricating oil composition by using, as a low friction sliding material exhibits a very low coefficient of friction with lubricating oil, further, by combining the lubricating oil composition and the sliding member having a sliding surface of the DLC film, and may provide a low friction sliding mechanism having excellent resistance to wear.
