Fuel composition comprising: (a) a base fuel suitable for use in an internal combustion engine; (b) a tetraalkylethane compound having the formula (I): wherein Ar represents an aryl group and each X is independently selected from a hydrogen atom, substituted or unsubstituted, straight chain or branched C-Calkyl group, (CH)OH or (CH)NH, wherein n is in the range of 1 to 9, provided that at least one of the X groups in each CXgroup is a hydrogen atom. The fuel composition of the present invention provides improved power and acceleration benefits, as well as increased flame speed and burn duration.

Fuel compositions

A fuel composition comprising a base fuel and at least one viscosity index (VI) improving additive, wherein the viscosity index (VI) improving additive is a functionalized dispersant olefin copolymer. The viscosity index (VI) improving additive provides improved power output and/or acceleration characteristics.

Use of a wax anti-settling agent (WASA), in an automotive fuel composition, for the purpose of improving the acceleration performance of an internal combustion engine into which the fuel composition is or is intended to be introduced or of a vehicle powered by such an engine.
