A lubricating composition contains a base oil and an organomolybdenum compound and has a sodium content of not greater than 200 ppm. The limited content of a sodium metal allows the organomolybdenum compound to fully exhibit its peculiar physical performance in that composition. Sufficient friction reduction can be achieved when the lubricating composition is applied as a lubricant composition. Excellent frictional and wearing properties are attainable when the lubricating composition is used as a grease composition. |
