Lubricating oil composition

A lubricating oil composition which contains a poly-alpha-olefin and an antioxidant, and which has an evaporation loss of 4.9 mass% or less as determined by the Noack method, a kinematic viscosity of 6.5 mm2/sec or less at 100 DEG C, and an amount of the antioxidant relative to the poly-alpha-olefin...

More Information
Summary:A lubricating oil composition which contains a poly-alpha-olefin and an antioxidant, and which has an evaporation loss of 4.9 mass% or less as determined by the Noack method, a kinematic viscosity of 6.5 mm2/sec or less at 100 DEG C, and an amount of the antioxidant relative to the poly-alpha-olefin of 0.05 mass% or more. 润滑油组合物，其含有聚α-烯烃和抗氧化剂，基于Noack法的蒸发减量为4.9质量％以下，100℃时的运动粘度为6.5mm2/秒以下，抗氧化剂相对于聚α-烯烃的量为0.05质量％以上。
