摘要：
The present invention provides a lubricating oil composition comprising a mixture of both a poly-alpha-olefin and an ester compound, the lubricating oil composition having an SAE viscosity grade of 75W-85, satisfying GL- 5 in terms of API gear oil designation and having a viscosity index of 160 or more. The above mixture of the poly-alpha-olefin and ester compound is preferably contained in an amount of from 75 to 90 wt% with reference to the total amount of the lubricating oil composition. The poly-alpha-olefin is preferably a mixture of a poly-alpha-olefin having low viscosity of from about 3 to 6 mm 2 /s at 100°C and a poly-alpha-olefin having high viscosity of from about 35 to 45 mm 2 /s at 100°C.
