LUBRICATING OIL COMPOSITION FOR INTERNAL COMBUSTION ENGINE |
摘要 |
The present invention provides a lubricating oil composition for internal combustion engines which can reduce sufficiently the friction under mixed lubricating conditions and is excellent in fuel saving properties. The lubricating oil composition comprises (A) a base oil having a 100°C kinematic viscosity of 2 to 8 mm 2 /s and an aromatic content of 10 percent by mass or less, (B) a metallic detergent having a metal ratio of 1.01 to 3.3 overbased with an alkaline earth metal borate, and (C) an organic molybdenum compound with a molybdenum concentration of 0.01 to 0.2 percent by mass on the basis of the total mass of the composition, and having a 100°C HTHS viscosity of 5.5 mPa·s or lower. |
