More Information
Summary:A lubricant composition comprising an oil of lubricating viscosity and an oil-soluble branched-chain hydrocarbyl-substituted arenesulfonic acid salt, wherein the arenesulfonic moiety has at least one hydrocarbyl substituent which is a highly branched group as defined by having a Chi(0)/Shadow XY ratio greater than about 0.180, exhibits good dynamic frictional performance.
