Friction modifiers for lubricating oils |
摘要 |
A lubricating oil comprising a major amount of a base oil and a minor amount of an additive package, and the additive package comprises at least one friction modifier selected from compounds of the formulae II, III and IV, and carboxylate salts thereof:;
wherein R is a linear or branched, saturated, unsaturated, or partially saturated hydrocarbyl having about 8 to about 28 carbon atoms, n is 0 or 1; and the carboxylate salts have a cation that is an alkali metal, alkaline earth metal, group IIB metal, or ammonium cation. Methods of using the engine oil to improve thin film and/or boundary layer friction in an engine are also provided. |
