Abstract: A fuel composition including a fuel and a fuel additive including a fuel soluble detergent selected from succinimide compounds of the Formula (I), Mannich detergents of the formulae (IIa), and amine detergents of the formulae (IIIa) and (IIIb). The fuel soluble detergents are derived from a specific class of ethylene-alpha olefin copolymers having an Mn of less than 5,000 g/mol, an ethylene unit content of more than 40 mol % to less than 90 mol %; a terminal unsaturation of 70 mol % or greater; at least 70 mol % of the unsaturation is terminal vinylidene, one or more tri-substituted isomers of the terminal vinylidene or any combination thereof, an average ethylene run length of less than 2.6; and wherein nC2,Actual>nC2,Statistical. Methods employing the fuel compositions for operating diesel and gasoline engines to reduce injector valve deposits, valve sticking and injector nozzle fouling, and a method for stabilizing a diesel fuel composition.
