LUBRICATING OIL COMPOSITION FOR SHOCK ABSORBER |
| 摘要 |
Provided is a lubricating oil composition for a shock absorber, which realizes excellent riding comfort in low-temperature and high-temperature environments and can suppress worsening of riding comfort with time, which is caused by evaporation and shearing of the lubricating oil. The lubricating oil composition for a shock absorber contains (A) a base oil having a pour point of lower than −40° C. and a kinematic viscosity at 80° C. of from 2.0 to 2.7 mm2/s, (B-1) from 1 to 15% by mass of a polymethacrylate having a weight-average molecular weight of from 10,000 to less than 100,000, and (B-2) from 0.1 to 5% by mass of a polymethacrylate having a weight-average molecular weight of from 100,000 to 200,000. |
