<p>An engine oil composition obtained by compounding: (A) a base oil mixture including a first base oil and a second base oil, the first base oil having a kinematic viscosity of 2 to 50 mm 2 /s at 100°C, a viscosity index of 80, and a sulfur content of less than 0.03 mass %, the second base oil having a kinematic viscosity of 2 to 50 mm 2 /s at 100°C, a viscosity index of 60, and a sulfur content of 0.03 mass % or more; (B) an oil-soluble molybdenum-containing composition; and (C) a molybdenum-based friction modifier; in which, based on the total amount of engine oil composition, the content of the second base oil is 0.1 to 15 mass %, the content of (B) oil-soluble molybdenum-containing composition is 10 to 1000 mass ppm in terms of amount of molybdenum, and the content of (C) molybdenum-based friction modifier is 100 to 1000 mass ppm in terms of amount of molybdenum.</p> |
