摘要： 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.

摘要： The invention provides a process for preparing a neutral or an overbased detergent, the process by: reacting (a) a pre-prepared suspension comprising (i) a metal base with a mean particle size of 10 micrometres or less; (ii) a surfactant; and (iii) an organic medium in which the metal base is suspended typically by a physical process. An overbased detergent may be formed with a further reaction with acidifying overbasing agent. The invention further provides a lubricant composition containing said neutral and overbased detergent.
