Abstract

As transmissions have become more compact and are run under conditions of higher speeds and higher loads, the conditions of use for lubricating oils have become more severe. To this end, the invention provides a lubricating oil composition comprising a metal dithiophosphate, regarded in the prior art as having low extreme-pressure characteristics, and a poly (meth) acrylate containing a polar hydroxyl group in a base oil. With this lubricating oil composition, the anti-seizing characteristics are good and the extreme-pressure characteristics are the same as or better than with sulphur/phosphorus type extreme-pressure agents. Also, the fatigue characteristics are low, oxidation stability is high and long life can be achieved.
