摘要 |
A lubricating oil composition for an internal combustion engine contains a component (A) of a polyalphaolefin having a kinematic viscosity at 100 degrees C. of 5.5 mm2/s or less, a CCS viscosity at −35 degrees C. of 3000 mPA·s or less and a NOACK of 12 mass % or less, and a component (B) of a mineral oil having a viscosity index of 120 or more. The component (A) is contained at a content of 25 mass % or more of a total amount of the composition.
