Abstract
An antigel fuel additive contains a polar long chain oxygenated hydrocarbon having a high molecular weight and having an acid number of 25 to 125, and preferably 50 to 100. The oxygenated hydrocarbon is combined with a hydrophillic precipitant such as a glycol ether, and hexanol, and a low molecular weight polyethylene-vinyl acetate copolymer. The additive need only be added in about 0.3 to 1 part per thousand parts of the particular fuel, to prevent the formation of wax particulates at low temperatures. Diesel and no. 2 heating oil fuels are contemplated uses.
