A lubricating oil composition may be used for lubrication of a shock absorber. The composition may include a base oil (A), a zinc dithiophosphate (B), and an alkenylsuccinic imide (C). The lubricating oil composition can be more preferably applied to lubrication of a shock absorber. Based on the total lubricating oil composition mass, a content of the component (C) in terms of nitrogen atoms is in a range of from 0.001 to 0.09 mass %, and/or a content of the component (B) in terms of zinc atoms is in a range of from 0.005 to 1.0 mass %.
