Abstract: 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 C1-C12 alkyl group, (CH2)nOH or (CH2)nNH2, wherein n is in the range of 1 to 9, provided that at least one of the X groups in each CX3 group is a hydrogen atom; and c) an alkylbenzene compound having the formula (II) wherein each R1-R6 group is independently selected from hydrogen and a C1-C15 alkyl group, wherein at least one of the R1-R6 groups is a C1-C6 alkyl group. The fuel composition of the present invention provides improved power and acceleration benefits, as well as increased flame speed and burn duration.
