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.

Abstract: Ethylene-C3-C10 alpha olefin copolymers, dispersants and lubricating oils/fuel compositions incorporating dispersants, and related methods are generally described herein. The copolymer may comprise ethylene-derived units and C3-C10 alpha-olefin-derived units. The C3-C10 alpha-olefin-derived units may have a carbon number from three to ten. For example, the C3-C10 alpha-olefin-derived units may be propylene-derived units. The dispersants may be made from copolymers having low metal and/or fluorine contents.
