Abstract

Distillate fuel oil boiling in the range 120 DEG C to 500 DEG C which has a wax content of at least 0.3 wt.% at a temperature of 10 DEG C below the Wax Appearance Temperature, the wax crystals at that temperature having an average particle size less than 4000 nanometres preferably less than 1000 nanometres.
