Abstract
A hydrocarbon fuel composition containing from 5 ppm to 500 ppm of a metal that normally catalyzes oxidative deterioration of said fuel composition is stabilized by incorporating in it from 1% to 25% by volume of a stabilizer that is an alkanol having 1 to 10 carbon atoms, a glycol having 2 to 9 carbon atoms, or a mixture thereof.

A diesel fuel composition stabilized against oxidative deterioration that consists essentially of diesel fuel containing from 5 ppm to 500 ppm of copper and from 1% to 25% by volume of a stabilizer selected from the group consisting of alkanols having from 1 to 10 carbon atoms, glycols having from 2 to 9 carbon atoms, and mixtures thereof.
A process for stabilizing diesel fuel against oxidative deterioration that consists of incorporating a stabilizer into a fuel composition consisting essentially of diesel fuel and from 5 ppm to 500 ppm of copper, said stabilizer selected from the group consisting of alkanols having from 1 to 10 carbon atoms, glycols having from 2 to 9 carbon atoms and mixtures thereof and being incorporated in amounts from 1% to 25% by volume based on the volume of said composition.
