Abstract (en)
[origin: EP2873720A1] The present invention provides a lubricating oil composition for an internal combustion engine that is excellent in functions as an engine oil for an internal combustion engine employing heat management and in particular fuel saving properties and detergency, comprising (A) a base oil having 100°C kinematic viscosity of 3.0 to 5.0 mm 2 /s and (B) a boronated succinimide in an amount of 0.007 percent by mass or more as boron and in an amount of 5 percent by mass or less as the succinimide ashless dispersant, on the basis of the total mass of the composition, (C) a phenol-based antioxidant in an amount of 0.5 percent by mass or more and (D) a viscosity index improver having a ratio of the weight average molecular weight and PSSI of 1.2 x 10 4 or greater in an amount of 0.1 to 5 percent by mass, the composition having a 150°C HTHS viscosity of 2.0 to 2.8 mPa·s, a 100°C HTHS viscosity of 4.8 mPa· s or lower and a viscosity index of 180 or greater.
