Abstract: Stable microemulsion fuel compositions are provided which comprise (a) a hydrocarbon fuel such as diesel fuel, jet fuel, gasoline, or fuel oil; (b) water and/or methanol; and (c) a novel cosurfactant combination of tertiary butyl alcohol and an ionic or nonionic surfactant. The compositions of the invention exhibit a high degree of phase stability even over wide variations of temperature, greatly improved salt tolerance and reduce smoke particulate and NO.sub.x emissions.
