Abstract
The invention provides the use of a highly paraffinic distillate fuel in a diesel fuel composition for reducing the formation of injector nozzle deposits when combusted in a diesel engine having a high pressure fuel injection system, wherein the distillate fuel has an aromatics content less than 0.1 wt %, a sulfur content less than 10 ppm and a paraffinic content of at least 70 wt %, such that the diesel fuel composition has a relative fouling behavior of 70% or less and a density of more than 0.815 g. cm(at 15° C.).
