## Abstract

The present invention relates to a fuel additive formulation applied to internal combustion engines formulated to reduce friction, corrosion, and wear in the internal combustion engines. The fuel additive in accordance with the present invention is a formulation of hexylene glycol and boric oxide. Reduction of engine wear and degradation due to reduction of friction and deposit formation is expected to result in increased engine efficiency, extension of engine life, and reduction in repair and maintenance costs.
