Abstract: A lubricating oil composition for an internal combustion engine, having (A) a lubricating base oil including one or more mineral oil-based base oils and having a kinematic viscosity at 100° C. of 2.5 mm2/s or more and 4.0 mm2/s or less, and (B) magnesium salicylate in an amount of 0.1 mass % or more and 10 mass % or less based on a total amount of the composition, wherein the composition has an HTHS viscosity at 150° C. of 1.6 mPa·s or more and 2.5 mPa·s or less. The lubricating oil composition for an internal combustion engine has both high fuel-saving performance and LSPI-reducing effect.
