Abstract: Lubricant compositions comprising (a) an oil of lubricating viscosity; and (b) at least one non-metal-containing additive, comprising a nitrogen-containing dispersant having a total base number of at least about 90 are useful for lubricating an internal combustion engine. The lubricants have less than 1.0% sulfated ash and a total base number of at least about 8.5, and at least 30% of the total base number of the composition is provided by non-metal-containing additives. The lubricants exhibit a high TBN without deterioration of elastomeric seals.

Abstract: A dispersant composition comprising the product of an amine, an alcohol, or an amino alcohol, with a hydrocarbyl-substituted succinic anhydride component exhibits improved viscosity stability and reduced chlorine content, when the hydrocarbyl-substituted succinic anhydride component comprises: (a) 10 to 95 weight percent of a component prepared by reacting a polyisobutylene with maleic anhydride in the presence of chlorine; and (b) 5 to 90 weight percent of a component prepared by reacting a polyisobutylene with maleic anhydride in the substantial absence of chlorine.

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.
