ADDITIVE COMPOSITIONS WITH PLURAL FRICTION MODIFIERS

摘要

1. A lubricating composition comprising a large amount of base oil and a minor amount of an additive package, wherein the additive package comprises: (A) a friction modifier component selected from the following: (a) at least one reaction product of an alcohol and a compound of formula IV: ; And (b) one or more compounds of the formula II-III: And [Wherein, R is a linear or branched, saturated, unsaturated or partially saturated hydrocarbyl having from about 8 to about 22 carbon atoms; R ₂ and R ₃ are independently selected from hydrogen, a C ₁ -C ₁₈ hydrocarbyl group, and a C ₁ -C ₁₈ hydrocarbyl group containing at least one heteroatom; X is an alkali metal, alkaline earth metal, or ammonium cation and n is a cation of cation X; And reaction products of amines, aminoalcohols, alkali or alkaline earth metal hydroxides, alkali or alkaline earth metal oxides and mixtures thereof with compounds of the formula IV: Wherein R is as defined above; And (B) at least one friction modifier different from at least one compound (A).
