| 发明名称 | Lubricating oil composition | ||
| 摘要 | The present invention provides a lubricating oil composition having fuel saving properties and providing gears and bearings with satisfactory durability, which is thus suitably used particularly for a gear system of an automobile. The lubricating oil composition a lubricating base oil comprising a mix base oil of (A) a mineral base oil having a 40° C. kinematic viscosity of 10 mm2/s or higher and 100 mm2/s or lower and (E) a mineral base oil having a 40° C. kinematic viscosity of 200 mm2/s or higher and 600 mm2/s or lower and a sulfur content of 0.3 to 0.9 percent by mass, the content of the base oil belonging to Component (B) is 15 percent by mass or more, and (C) and an organic molybdenum compound in an amount of 100 to 1000 ppm by mass as molybdenum, the lubricating oil composition having a 40° C. kinematic viscosity of 90 mm2/s or lower. | ||
