    Abstract: PROBLEM TO BE SOLVED: To provide a lubricating oil composition for wet clutches which, even when used in a 4-stroke internal combustion engine for a two-wheel motor vehicle, suppresses the formation of insolubles such as sludge and varnish due to deterioration and the clogging of the wet clutch with the insolubles and is keeping the frictional characteristics and power transmission performance of the wet clutch sufficiently over a long term. SOLUTION: The lubricating oil composition for wet clutches is prepared by formulating a lubricating oil base oil containing not less than 90 mass% saturated components in which cyclic saturated components account for 40 mass% or more and having a viscosity index of 110 or higher and an iodine value of 2.5 or smaller with, based on the entire amount of the composition, 0.5-3 mass% ashless antioxidant and 3-12 mass% ashless dispersant.
