Zusammenfassung: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 mm 2 /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 10 mass% or more of a total amount of the composition.
