To provide a lubricating oil composition for an automobile shock absorber capable of moderately increasing the frictional force at a sliding portion of an automobile shock absorber such as the part between a piston rod and an oil seal and between a piston band and a cylinder and improving the steering stability of an automobile on high-speed running, the danger avoiding performance, the turning performance on a winding road, etc.
The lubricating oil composition for an automobile shock absorber comprises compounding a base oil for the lubricating oil with (A) 0.01-1 mass% of an acidic phosphorous acid diester, (B) 0.02-0.6 mass% of an acidic phosphoric acid ester or its amine salt and (C) 0.5-15 mass% of a dispersed viscosity index improving agent based on the total mass of the composition.
