Abstract:
A fuel additive composition includes a polyalkenylsuccinimide, a mono or polyfunctional polyisobutene amine, and a carrier oil selected from the group of mineral oils, polyethers, polyetheramines, esters, and combinations thereof. The polyalkenylsuccinimide includes the reaction product of a hydrocarbyl dicarboxylic acid producing reaction intermediate and a nucleophilic reactant. The hydrocarbyl dicarboxylic acid producing reaction intermediate includes the reaction product of a polyolefin comprising C2 to Ci8 olefin units and having a number average molecular weight (Mn) of about 500 to 5,000 g/mol and a C4 to Cio monounsaturated acid reactant. The hydrocarbyl dicarboxylic acid producing reaction intermediate includes from 0.5 to 10 dicarboxylic acid producing moieties per molecule of the polyolefin. The nucleophilic reactant is selected from the group of amines, alcohols, amino alcohols, and combinations thereof.
