Abstract: A multigrade lubricating oil composition with enhanced anti-wear properties for use in an internal combustion engine comprises (a) a base oil comprising at least 90% by weight of the base oil, of one or more basestocks selected from the group consisting of base stocks derived from Fischer-Tropsch synthesised, waxy, paraffinic hydrocarbon material by processes comprising hydrocracking and/or hydroisomerisation, Group II basestocks, Group III basestocks and mixtures thereof; (b) one or more dispersant viscosity modifiers in a total amount of 0.15 to 0.8% by weight of the composition; (c) one or more dispersants in a total amount of active dispersants of 1.5 to 3% by weight of the composition; (d) one or more detergents; and (e) one or more metal dihydrocarbyl dithiophosphates.
