Abstract
A fuel additive composition comprising: PA1 (a) a fuel-soluble aliphatic hydrocarbyl-substituted amine having at least one basic nitrogen atom wherein the hydrocarbyl group has a number average molecular weight of about 700 to 3,000; PA1 (b) a polyolefin polymer of a C.sub.2 to C.sub.6 monoolefin, wherein the polymer has a number average molecular weight of about 350 to 3,000; and PA1 (c) a hydrocarbyl-terminated poly(oxyalkylene) monool having an average molecular weight of about 500 to about 5,000, wherein the oxyalkylene group is a C.sub.2 to C.sub.5 oxyalkylene group and the hydrocarbyl group is a C.sub.1 to C.sub.30 hydrocarbyl group.
