LUBRICATING OIL COMPOSITION, INTERNAL COMBUSTION ENGINE, AND METHOD FOR LUBRICATING INTERNAL COMBUSTION ENGINE

WIPO Patent Application WO/2017/164319

A1

Provided is a lubricating oil composition comprising: a base oil (A) containing a mineral oil (A1) having a complex viscosity η* of 150 Pa·s or less at -35°C as measured using a rotational rheometer under conditions where the angular velocity is 6.3 rad/s and the strain level is 0.1%; a viscosity index improver (B) containing a comb polymer (B1); and a molybdenum-based friction adjuster (C), wherein the contained amount of the component (C) in terms of molybdenum atoms is more than 500 ppm by mass but less than 900 ppm by mass with respect to the total amount of the lubricating oil composition, and the lubricating oil composition has a NOACK value of 10 mass% or less.
