Poly(alkylene ether) amines having the formula: ##STR1## wherein A is an amine moiety having at least one basic nitrogen atom; R.sub.1 is a hydrocarbyl group having a sufficient number of carbon atoms to render the poly(vinyl ether) amine soluble in hydrocarbons boiling in the gasoline or diesel fuel range; R.sub.2 is an alkylene group having 2 to about 8 carbon atoms; R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 are each independently hydrogen or a lower alkyl group having 1 to about 4 carbon atoms; R.sub.9 is an alkyl group having 1 to about 10 carbon atoms; m is 0 or 1; n is an integer from 5 to 99; and W is a hydroxy(oxypropylene) group having the formula: ##STR2## or mixtures thereof. The poly(vinyl ether) amines of formula I are useful as fuel additives for the prevention and control of engine deposits.
