    摘要: A lubricating oil composition having a total base number of more than 15 mg KOH/g including oil of lubricating viscosity; detergent; and at least one compound of the formula (I) and/or formula (II): wherein Ar and Ar′ represent substituted or unsubstituted aromatic moieties; L and L′ are linking moieties; each Y is independently —ORI″or H(O(CR12)n)yX—, wherein X is (CR1′2)z, O or S; R1 and R1′ are H, alkyl or aryl; R1″ is alkyl or aryl; each Y′ is independently Z(O(CR22)n′)y′X′—, wherein X′ is (CR2′2)z′, O or S; R2 and R2′ are H, alkyl or aryl; Z is H, acyl, alkyl or aryl; z and z′ are 1 to 10; n is 0 to 10 when X is (CR1′2)z and 2 to 10 when X is O or S; n′ is 0 to 10 when X′ is (CR2′2)z′, and 2 to 10 when X′ is O or S; y and y′ are 1 to 30; a and a′ are 0 to 3; and m and m′ are 1 to 100, with the proviso that in compounds of formula (I), at least one Ar moiety bears at least one group Y and that in compounds of formula (II), at least one Ar′ moiety bears at least one group Y′ in wherein Z is not H.
