The present invention provides a lubricating oil composition for an internal combustion engine excellent in fuel economy saving by further reducing friction. (A) having a kinematic viscosity of 2.0 to 5.0mm 2 / s of the lubricating oil base oil, (B) a molybdenum-based friction modifier to the total amount of the composition based on an amount of molybdenum of 0.005 to 0.2% by mass, (C) a metal-based detergent composition in 100 ℃ Containing 0.01 to 10% by mass of at least one compound selected from amino acids and / or derivatives thereof having an alkyl group, alkenyl group or acyl group having a metal content of 0.01 to 1% by mass and (D) Lubricant composition for engines. |
