摘要

A fuel additive composition comprising: a) a fuel-soluble aliphatic hydrocarbyl-substituted amine having at least one basic nitrogen atom wherei n the hydrocarbyl group has a number average molecular weight of about 700 to 3,000; b) a polyolefin polymer of a C2 to C6 monoolefin, wherein the polymer has a number average molecular weight of about 350 to 3,000; and c) an aromatic di- or tri-carboxylic acid ester of formula (I), wherein R is an alkyl group of 4 to 20 carbon atoms, and x is 2 or 3.
