Abstract

An internal combustion engine crankcase lubricating oil composition 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 and one block being derived from a diene monomer.
