Abstract: A fuel conditioner comprises a polar oxygenated hydrocarbon having a molecular weight from about 250 to about 500; an acid number of from about 25 to about 125, preferably from 50 to 100; and a saponification number from about 30 to about 250. The polar compound is combined with a compatibilizing agent such as an alcohol. An aromatic hydrocarbon and/or a hydrocarbon base stock may also be employed. For internal combustion engines which do not recycle exhaust to heat the fuel, a hydrophilic separant is added to cause any water present to form a separate layer. The conditioner is intended for use in internal combustion engines burning gasoline, diesel fuel, or hydrocarbon/alcohol fuels, and for boilers burning No. 2 oil and the like. Use of the fuel conditioner decreases fuel consumption, decreases engine wear, reduces carbonaceous deposits, and lowers "octane" requirements.

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.
