The antifriction properties of calcium phenate‐, sulphonate‐ and alkylsalicylate‐type detergent additives were investigated. The influence of the detergent type and its basicity on engine oil antifriction properties was determined. The tribological performance of different detergents was characterised by laboratory methods. Auger spectroscopy was used for surface layer composition and thickness determination. The experimental data allowed the mechanism of action and the tribological performance characteristics of overbased detergents to be more precisely identified.
