A fuel composition comprising a major amount of a normally liquid fuel and a minor amount of at least one compound of the general formula [Figure] (I) wherein each Ar is independently an aromatic group having from 4 to about 30 carbon atoms and from 0 to 3 optional substituents selected from the gro
A fuel composition comprising a major amount of a normally liquid fuel and a minor amount of at least one compound of the general formula [Figure] (I) wherein each Ar is independently an aromatic group having from 4 to about 30 carbon atoms and from 0 to 3 optional substituents selected from the group consisting of amino, hydroxy- or alkyl- polyoxyalkyl, nitro, aminoalkyl, carboxy or combinations of two or more of said optional substituents, each R is independently a hydrocarbyl group, R1 is H or a hydrocarbyl group, R2 and R3 are each, independently, H or a hydrocarbyl group, R4 is a monovalent terminating group, each m is independently 0 or an integer ranging from 1 to about 10, x ranges from 0 to about 8, and each Z is independently OH, lower alkoxy, (OR5)bOR6 or O-wherein each R5 is independently a divalent hydrocarbyl group, R6 is H or hydrocarbyl and b is a number ranging from 1 to about 30 and c ranges from 1 to about 3, y is a number ranging from 1 to about 10 and wherein the sum m+c does not exceed the number of valences of the corresponding Ar available for substitution and at least one A is independently an amide or an amide-containing group. In one embodiment, (I) is present in an amount effective to provide total fuel intake system cleanliness in a port fuel injected internal combustion engine.
