LUBRICATING OIL COMPOSITION FOR TRANSMISSIONS |
| 摘要 |
The present invention provides a lubricating oil composition for transmissions which is improved in fuel saving properties and has excellent metal fatigue prevention properties and heat resistance. The lubricating oil composition comprises (A) a mineral base oil having a 100° C. kinematic viscosity of 1.5 mm2/s or higher and 3.5 mm2/s or lower, a pour point of −25° C. or lower, a viscosity index of 110 or greater, a % CN of 2 or greater and 20 or less and a % CA of 3 or less, the lubricating oil composition having a 100° C. kinematic viscosity of 2.5 mm2/s or higher and 3.8 mm2/s or lower. |
