Fuel compositions containing hydroxyalkyl-substituted amines

1. Field of the Invention A fuel composition comprising a major amount of hydrocarbons boiling in the gasoline or diesel range and an effective detergent amount of a hydroxyalkyl-substituted amine which is the reaction product of:(a) a polyolefin epoxide derived from a branched chain polyolefin having an average molecular weight of about 400 to 5,000; and(b) an amine having the formula: wherein Rand Rare independently selected from the group consisting of hydrogen and hydrocarbyl of 1 to about 20 carbon atoms and, when taken together, Rand Rmay form one or more 5- or 6-membered rings containing up to about 20 carbon atoms.
