Abstract
The purpose of the present invention is to provide a lubricating oil composition capable of achieving good wear resistance and good scoring resistance of a bearing in addition to further fuel saving while maintaining durability and seizure resistance that can be used as a gear oil for a high-output, high-speed gear mechanism. A lubricating oil composition containing a combination of Fischer-Tropsch derived base oil having a low kinematic viscosity at high temperature, polyalphaolefin having a high kinematic viscosity at high temperature, and ester compound of a trivalent or higher polyol having a low kinematic viscosity at high temperature, and further contains a partial ester compound of an unsaturated fatty acid and a polyol, including a monoester compound of the unsaturated fatty acid and the polyol.

Abstract
The purpose of the present invention is to provide a lubricant composition which can be applied as a gear oil for a high-output and high-speed gear mechanism, and whereby fuel saving as well as further wear resistance in a bearing of a pinion gear can be realized while maintaining excellent durability, seizure resistance, and stability are maintained. A lubricant composition containing a Fischer-Tropsch-derived base oil, a poly alpha-olefin, and an ester compound, and further containing an unsaturated fatty acid and/or a partial ester compound of an unsaturated fatty acid and a polyol, wherein the partial ester compound of an unsaturated fatty acid includes a monoester compound of an unsaturated fatty acid and a polyol in a ratio of 50% by mass with respect to the total amount of the partial ester compound, and the SAE viscosity grade of the lubricant composition is 75W-85 or lower.
