PROBLEM TO BE SOLVED: To provide a shock absorber lubricant composition excellent in ride comfort in low and high temperature environments and capable of suppressing over-time deterioration of ride comfort caused by the volatilization and shear of a lubricant.SOLUTION: The shock absorber lubricant composition comprises: (A) a base oil having a pour point of less than -40°C and a kinematic viscosity of 2.0-2.7 mm/s at 80°C; (B-1) 1-15 mass% of polymethacrylate having a weight average molecular weight of 10,000 or more and less than 100,000; and (B-2) 0.1-5 mass% of a polymethacrylate having a weight average molecular weight of 100,000 or more and 200,000 or less. |
