Abstract: A liquid fuel composition is provided that is suitable use in a spark ignition engine; the composition comprises a mixture of hydrocarbons and exhibits a vapour pressure of greater than around 25 kPa and below around 50 kPa. The composition provides improvements in fuel 5 economy particularly in hybrid electric vehicles that comprise a gasoline-powered internal combustion engine as part of the powertrain. Methods and uses of the compositions are also provided.

Abstract: A liquid fuel composition for a spark ignition internal combustion engine comprising (a) gasoline blending components, (b) Fischer-Tropsch derived naphtha at a level of up to 50% v/v and (c) oxygenated hydrocarbon at a level less than 50% v/v. While the low octane number of Fischer-Tropsch derived naphtha would normally severely restrict its blendability in gasoline to low levels, it has now been found that Fischer-Tropsch derived naphtha can be included in, for example, ethanol-containing gasoline fuel compositions, in surprisingly and significantly high blend ratios of Fischer-Tropsch derived naphtha to ethanol.
