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 the formula: ##STR1## where A.sub.1 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; R.sub.1 and R.sub.2 are independently hydrogen, hydroxy, lower alkyl, or lower alkoxy; R.sub.3 and R.sub.4 are independently hydrogen or lower alkyl and each R.sub.3 and R.sub.4 is independently selected in each --O--CHR.sub.3 --CHR.sub.4 -- unit; R.sub.5 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 the formula: ##STR2## where R.sub.6 is alkyl having 1 to 30 carbon atoms, phenyl, aralkyl having 7 to 36 carbon atoms or alkaryl having 7 to 36 carbon atoms; R.sub.7 and R.sub.8 are independently hydrogen, hydroxy, lower alkyl, or lower alkoxy; A.sub.2 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.
