    Abstract: Fuel compositions containing a major amount of hydrocarbons boiling in the gasoline or diesel range and an effective deposit-controlling amount of a poly(oxyalkylene) aromatic ester having formula (I) where A1 is nitro, amino, N-alkylamino wherein the alkyl group contains 1 to 6 carbon atoms, or N,N-dialkylamino wherein each alkyl group independently contains 1 to 6 carbon atoms; R1 and R2 are independently hydrogen, hydroxy, lower alkyl, or lower alkoxy; R3 and R4 are independently hydrogen or lower alkyl, and each R3 and R4 is independently selected in each -O-CHR3-CHR4- unit; R5 is hydrogen, alkyl having 1 to 100 carbon atoms, phenyl, aralkyl having 7 to 100 carbon atoms or alkaryl having 7 to 100 carbon atoms, or an acyl group of formula (a) or (b) where R6 is alkyl having 1 to 30 carbon atoms, phenyl, aralkyl having 7 to 36 carbon atoms or alkaryl having 7 to 36 carbon atoms; R7 and R8 are independently hydrogen, hydroxy, lower alkyl, or lower alkoxy; A2 is a nitro, amino, N-alkylamino wherein the alkyl group contains 1 to 6 carbon atoms, or N,N-dialkylamino wherein each alkyl group independently contains 1 to 6 carbon atoms; n is an integer from 5 to 100; and x and y are each independently integers from 0 to 10.
