Abstract: Gasoline fuel composition suitable for use in an internal combustion engine comprising: (a) Fischer-Tropsch derived naphtha at a level from 2 to 20% v/v; (b) at least one aromatic octane booster present at a level of 0.75 to 8% v/v or less; and (c) a gasoline base fuel; wherein the gasoline fuel composition comprises 40% v/v or less of aromatics. In a preferred embodiment, the Research Octane Number (RON) of the gasoline fuel composition is increased while maintaining the aromatic content of the gasoline fuel composition at a level of 40% v/v or less, based on the gasoline fuel composition.

Abstract: A process for reducing injector deposits in an internal combustion engine fuelled with a fuel composition, the process comprising contacting a fuel composition with a metal-selective membrane situated in the fuel delivery system. The reduction of such deposits provides an increase in fuel efficiency, fuel thermal stability, boost in engine cleanliness, improves fuel economy and enables the possibility of using a reduced amount of expensive detergent in the fuel composition.
