A fuel composition comprising a major amount of a normally liquid fuel and a minor but carburetor cleaning or anti-screen clogging amount of a product made by the process comprising reacting at a temperature ranging from 100° C. to about 300° C. (A) at least one alpha haloalkyl aromatic compound of the general formula ##STR21## wherein Ar is a hydrocarbyl aromatic nucleus of 6 to about 30 carbon atoms, or a substituted analog of such an aromatic nucleus substituted with one or more up to 3 each of lower alkoxy, lower alkylthio, chloro, or nitro substituents, each R is a nonfused hydrocarbyl group of about 25 to about 700 carbon atoms, X is a halogen atom, each R' is independently a hydrogen atom, an alkyl group of 1 to 36 carbon atoms, or a halogen-substituted alkyl group of 1 to about 36 carbon atoms, n is 1 to 3 and m is 1 to 5 with the provisos that (i) the total number of carbon atoms in both the R' groups does not exceed 36 and (ii) where m exceeds 1, one of the R groups can also be ##STR22## group, with (B) at least one alpha-beta olefinically unsaturated compound selected from the group consisting of C 2-40 hydrocarbyl nitriles, C 2-40 hydrocarbyl carboxylic acids and anhydrides, esters, amides and ammonium and metal salts of said C 2-40 carboxylic acids; the ratio of (A) to (B) is between about 0.5:1 to about 2:1, the reaction of (A) with (B) resulting in the formation of a carbon-to-carbon bond, said bond including the carbon of at least one ##STR23## group.
