Abstract: A low pour point gas turbine fuel is prepared from a waxy crude by blending a 650*-750*F distillate fraction from a crude oil with a minor amount of a 350*-650*F fraction of a middle distillate and from 0.05 to 0.5% by weight of an oil soluble ethylene-vinyl fatty acid ester copolymer in which the fatty acid component of the ester has a carbon content of from about 2 to about 6; the copolymer having a molecular weight between about 17,000 and 29,000, and a vinyl fatty acid ester content of from about 27 to about 42. The melt index of the copolymer ranges from 7 to 465.
