More Information
Summary:A fuel additive composition comprising: a) a Mannich condensation product of (1) a high molecular weight alkyl-substituted hydroxyaromatic compound; (2) an amine having the formula: wherein A is CH or nitrogen, R1, R2, R3 are independently hydrogen or lower alkyl of 1 to about 6 carbon atoms and each R2 and R3 is independently selected in each -CR2R3- unit, and x is an integer from 1 to about 6; and (3) an aldehyde, wherein the respective molar ratio of reactants (1), (2), and (3) is 1:0.1-2:0.1-2; b) a hydrocarbyl-terminated poly(oxyalkylene) monool; and c) a carboxylic acid as represented by the formula: R4(COOH)y or anhydride thereof, wherein R4 represents a hydrocarbyl group having about 2 to about 50 carbon atoms, and y represents an integer of 1 to about 4.
