ABSTRACT:
A fuel composition is provided containing (i) a base fuel, (ii) a Fischer-Tropsch derived gas oil and (iii) an oxygenate. The components (ii) and (iii) can be used in a tertiary fuel blend with a base fuel (i) for the purpose of achieving for the composition (a) a neutral or close to neutral effect on elastomeric components compared to that of the base fuel, and/or (b) a neutral or better emissions performance (in particular with respect to NOxand/or particulate emissions) compared to that of the base fuel, preferably in addition to a neutral or close to neutral density for the composition with respect to that of the base fuel.
