Abstract

An internal combustion engine crankcase lubricating oil composition which reduces the cam and lifter wear has a phosphorus content of not greater than 0.09 mass %, a metal detergent additive system comprising one or more metal salts of organic carboxylic acids, and a viscosity index improver comprising a linear diblock copolymer, one block being derived from a vinyl aromatic hydrocarbon monomer such as styrene and one block being derived from a diene monomer such as isoprene or butadiene.
