Abstract: A novel nonacidic fuel additive which is soluable in gasoline, diesel fuels and other liquid aliphatic hydrocarbons, and which comprises the product produced by mixing ketone peroxides, ketones, a Group III metal, an alcohol, and borontrifloride, or liquid cobalt, or a chlorobenzine. The fuel additive further comprises a ketone solvent, said ketones preferrably being methyl ethyl ketones and their peroxides and solvents. The fuel additive of the present invention, serves to increase power output, lower the ignition point of the carrier fuel, increase mileage, and, especially when used with diesel, reduces the effect of cold temperatures on the viscosity, turbidity, and color of the diesel fuel to temperatures as severe as -40.degree.
