Abstract: Disclosed is a leaded motor fuel additive composition which synergistically interacts with the alkyl lead additive to reduce both fuel intake system deposit formation and combustion chamber deposit formation, thereby reducing engine ORI and maintaining desired engine performance.

Abstract: A motor fuel additive composition comprises a mixture of: (a) from about 5 to about 50 weight percent, based upon the total weight of the additive, of a detergent component selected from the group consisting of (i) a reaction product of a substituted hydrocarbon and an amino compound, and (ii) a polybutylamine or polyisobutylamine; and (b) a fuel conditioner component comprising (i) from about 2 to about 50 weight percent, based upon the total weight of the additive, of a polar oxygenated hydrocarbon compound and (ii) from about 2 to about 50 weight percent, based upon the total weight of the additive, of an oxygenated compatibilizing agent. The fuel conditioner component may additionally comprise a hydrophilic separant, an aromatic hydrocarbon, or mixtures thereof. Additionally, in some cases the hydrophilic separant may also act as the compatibilizing agent. The additive may also additionally comprise a carrier oil or fluidizer.

Abstract: An antigel composition for hydrocarbon fuels for combustion in motors, engines, turbines, and furnaces comprises:(a) a polar oxygenated long chain hydrocarbon having a defined acid number, a defined saponification number, and a defined molecular weight;(b) a low molecular weight addition polymer or copolymer, preferably of ethylene and vinyl acetate;(c) optionally, a hydrophilic conditioner, selected from the group consisting of glycols, glycol diether, and half ethers preferably a methyl half ether of a glycol; and(d) optionally, a compatibilizing agent, preferably having a solubility parameter from about 8.8 to about 11.5, more preferably an alcohol having from 4 to 13 carbon atoms.

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.

Abstract: A non-ionic composition for dispersing sludge and causing rapid separation of water for easy removal, in residual oils, is formed from a blend of n-hexanol, diethylene glycol methyl ether and isooctyl phenyl polyethoxy ethanol. The dispersant, when used in 1:1,000-4,000 parts of dispersant to parts of oil, causes dispersion of the sludge and eliminates the need for physically removing the sludge.
