Abstract
A fuel additive formulation, method of use, and method of producing the fuel additive formulation are described. The fuel additive of the present disclosure comprises a mixture of nitroparaffins comprising nitropropane and nitromethane, a lubricant, and an aromatic hydrocarbon. The fuel additive formulation is substantially free of nitroethane. The combustion in an internal combustion engine of a fuel containing the additive results in reduced emissions relative to the combustion of a fuel not containing the additive.
