Abstract: A method for lubricating a diesel engine equipped with an exhaust gas recirculation, comprising supplying thereto a composition comprising an oil of lubricating viscosity and the reaction product of a polymer comprising carboxylic acid functionality and having a number average molecular weight of greater than 5000 and an aromatic amine with at least one amino group capable of condensing with the carboxylic acid and at least one additional group comprising at least one nitrogen, oxygen or sulfur atom. The aromatic amine is selected from (i) nitro-substituted aniline, (ii) amines comprising two aromatic moieties linked by a -C(O)NR-, -C(O)-, -O-, -N=N-, OR -SO2- group, where R is hydrogen or hydrocarbyl, one of said aromatic moieties bearing said condensable amino group (iii) an aminoquinoline, (iv) an aminobenzimidazole, (v) an N, N-dialkylphenylenediamine, and (vi) a ring-substituted benzylamine. Reaction of a carboxylic acid-containing polymer with certain aromatic amines results in dispersant viscosity modifiers with improved soot handling performance in heavy-duty diesel engines, compared with reaction with non-aromatic amines.
