Abstract
The present invention is directed to a composition containingA) at least one polyalkenene substituted amine; andB) at least one hydrocarbyl-terminated poly(oxypropylene) monool represented by the formula wherein in formula (B-I), R is an alkyl or an alkyl-substituted aromatic group of about 8 to about 20 carbon atoms; x is a number from about 13 to about 28; and wherein the weight ratio of component (A) to component (B) ranges from about 10:1 to about 1:10.The composition is useful as a fuel additive for reducing intake valve deposits or for improving the valve stick performance of an internal combustion engine. The invention also relates to concentrates and fuel compositions containing the foregoing fuel additive composition and to a method for reducing intake valve deposits or for improving the valve stick performance of an internal combustion engine.
