Abstract:
A fuel additive composition comprising:a) a Mannich condensation product of (1) a high molecular weight alkyl-substituted hydroxyaromatic compound wherein the alkyl group has a number average molecular weight of from 300 to about 5,000 (2) an amine which contains an amino group having at least one active hydrogen atom, and (3) an aldehyde, wherein the respective molar ratio of reactants (1), (2), and (3) is 1:0.1-10:0.1-10; b) a hydrocarbyl-terminated poly(oxyalkylene) monool having an average molecular weight of about 500 to about 5,000, wherein the oxyalkylene group is a C2 to C5 oxyalkylene group and the hydrocarbyl group is a C1 to C30 hydrocarbyl group; c) a polyolefin polymer of a C2 to C6 mono-olefin, wherein the polymer has a number average molecular weight of about 500 to about 3,000; and d) a monocarboxylic acid having about 8 to about 30 carbon atom.
