LUBRICANT OIL COMPOSITION AND BLEND ADDITIVE PACKAGE

摘要

Lubricating oil dispersancy is improved by the use of a novel composition comprising a synergistic mixture of a boronated hydrocarbon-substituted succinic amide/imide/ester of an oxyalkylated amine and a Mannich condensation product of a hydrocarbon-substituted phenol, formaldehyde and an amine, and, optionally, a fatty acid and/or a boronating agent. The invention includes such compositions, the ingredients of such a composition when intended for such use, lubricating oil compositions containing the same ingredients, a method of improving lubricating oil dispersancy using the same ingredients and additive packages for lubricating oil using the same ingredients.
