Abstract
Abstract A fuel additive for use in the treatment of liquid hydrocarbon fuels to reduce polluting emissions during the combustion of such fuels wherein the additive composition is formulated to contain mineral seal oil, mineral spirits, a glycol alkyl ether and at least one alkyl aromatic ethoxylated surfactant. It has been found that the fuel additive composition of the invention can be blended with such fuels to dramatically reduce emissions during the combustion of such fuels.
