Abstract
Fuel compositions containing a hydrocarbon blend having a cetane number of at least 62, a kinematic viscosity at 40° C. of greater than 3.0 cSt and a density at 15° C. of greater than 830 kg/mis disclosed. The Wear Scar value of the fuel composition is below 350 microns as determined by CEC-F-06-A-96 and/or contains (b) a paraffinic fuel boiling in the gas oil range comprising more than 90 wt % paraffins and having a cetane number of between 70 and 85 in combination with (a) a mineral derived gas oil having a density at 15° C. of between 800 and 860 kg/mand a kinematic viscosity at 40° C. of between 1.5 and 15 cSt (mm/s) and/or (c) a naphthenic rich blending component boiling in the gas oil range having a density at 15° C. of greater than 860 kg/mand having a pour point of below −30° C.
