    Abstract: A fuel composition comprising a major amount of hydrocarbons boiling in the gasoline or diesel range and a fuel additive composition comprising (a) about 15 to 2,000 parts per million by weight of an aromatic ester of a polyalkylphenoxyalkanol, (b) about 30 to 2,000 parts per million by weight of a poly(oxyalkylene) amine, and (c) about 30 to 2,000 parts per million by weight of an aromatic di- or tri-carboxylic acid ester; wherein the total amount of components (a) and (b) is at least about 70 parts per million by weight, and further wherein the weight ratio of component (c) to the total amount of components (a) and (b) is at least about 0.25 to 1. The fuel compositions of this invention are useful for the prevention and control of engine deposits.
