Abstract

There is described a fuel additive composition comprising an alkanolamide, an alkoxylated alcohol, an alkoxylated fatty acid, or a derivative thereof, in which the degree of alkoxylation of the C 18 to C 22 fatty acid is from 0.5 to 5 mols of alkoxylate to 1 mol of fatty acid. There is also described a fuel composition comprising a liquid hydrocarbon fuel and a surfactant composition according to the invention. A method of running an internal combustion engine comprising the use of such a fuel is also described.
