LUBRICATING OIL COMPOSITION |
| 摘要 |
A lubricating oil composition contains: a first base oil with a kinematic viscosity at 100 degrees C. in a range from 1.5 mm2/s to 3.5 mm2/s; a second base oil with a kinematic viscosity at 100 degrees C. in a range more than 3.5 mm2/s but not more than 100 mm2/s; polymethacrylate with a mass average molecular weight in a range from 1×104 to 4×104; and a sulfur compound. The lubricating oil composition has a kinematic viscosity at 100 degrees C. in a range from 5 mm2/s to 6 mm2/s and a viscosity index of 200 or more. |

1. A lubricating oil composition, the lubricating oil composition comprising:
a first base oil with a kinematic viscosity at 100 degrees C. in a range of 1.5 mm2/S to 3.5 mm2/S; a second base oil with a kinematic viscosity at 100 degrees C. in a range more than 3.5 mm2/s and less than 100 mm2/s; polymethacrylate with a mass average molecular weight in a range of 1×104 to 4×104; and a sulfur compound; wherein the lubricating oil composition has a kinematic viscosity at 100 degrees C. in a range of 5 mm2/s to 6 mm2/s and a viscosity index of 200 or more. |
