    Abstract: The present invention is directed to a fuel additive composition comprising at least two components:(A) a polyether alcohol of the formula ##STR1## wherein in formula (A-1), R is hydrogen or a hydrocarbyl group of 1 to about 30 carbon atoms; R.sup.1 is hydrogen or a hydrocarbyl group of 1 to 5 carbon atoms or mixtures thereof; and x is a number from about 4 to about 40.(B) a hydrocarbylphenol having 1-3 hydrocarbyl groups such that the total weight average molecular weight of the hydrocarbyl groups is about 250 to about 6000.In one embodiment the composition further comprises (C) a nitrogen-containing dispersant.The composition is useful as a fuel additive for reducing intake valve deposits and advantageously, does not contribute to an increase in combustion chamber deposits in port fuel injected internal combustion engines. The invention also relates to concentrates and fuel compositions containing the foregoing fuel additive composition and to a method for fueling an internal combustion engine.

    Abstract: The present invention is directed to a fuel additive composition containing (i) a polyether alcohol of the formula ##STR1## wherein R is hydrogen or a hydrocarbyl group of 1 to about 30 carbon atoms; R.sup.1 is hydrogen or a hydrocarbyl group of 1 to 5 carbon atoms or mixtures thereof provided that no more than 10 mole % of R.sup.1 is hydrogen and where the polyether alcohol is soluble in gasoline; and x is a number from about 4 to about 40; (ii) a hydrocarbylphenol having 1-3 hydrocarbyl groups such that the total weight average molecular weight of the hydrocarbyl groups is about 250 to about 6000; and (iii) optionally a third component containing a nitrogen-containing dispersant; wherein the weight ratio of the polyether alcohol to the hydrocarbylphenol is about 3:1 to about 1:20. The compositions are useful in reducing intake valve deposit and do not contribute to the increase in combustion chamber deposit in port fuel injected engines.
