Abstract: 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.

Abstract: The present invention provides a multipurpose overbased metal salt of the reaction product of a hydrocarbyl substituted amine with an itaconate, such as an N-substituted 4-carboxypyrrolidin-2-one, and methods of employing the same in lubricating compositions. Overbasing the N-substituted 4-carboxypyrrolidin-2-one can provide improved friction modifying performance to the compound as well as impart multi-functionality to the compound, i.e., the compound may function as a friction modifier as well as, for example, a detergent, anti-wear or extreme pressure agent and dispersant in lubricating compositions. The lubricating compositions containing the overbased N-substituted 4-carboxypyrrolidin-2-one are preferably intended to be employed in a method for lubricating a mechanical device, such as an automatic or manual transmission. However, it is envisioned that the compound can be employed in engine oil lubricants and any other type of functional fluid.

Abstract: A lubricant comprising (a) an oil of lubricating viscosity; and (b) an overbased, carbonated calcium arylsulfonate detergent having a total base number (TBN) of at least about 640 as calculated on an oil-free basis effectively lubricates non-metallic surfaces in the synchronizer of a manual transmission.

Abstract: 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.
