摘要： Provided are a lubricant composition for shock absorbers, a lubricant additive, and a method of adjusting frictional property of a lubricant composition for shock absorbers, each capable of satisfying both the steering stability and ride comfort. The lubricant composition for shock absorbers contains a base oil and pentaerythritol esters and having frictional property represented by the following formula (1):

RI>1.75×Fave−0.05 (1)

supposing that a ratio ({Fsa−Fave}/Fave) of a difference, at the time of minute amplitude, between a peak frictional force Fsa in transition from a stationary state to a sliding state and an average frictional force Fave to the average frictional force Fave at the time of minute amplitude is responsiveness RI.
