An efficient and cost competitive fuel extender for mixing with lead-free gasoline used for driving internal combustion engines is provided which makes use of low grade, inexpensive naphtha as its principal ingredient that is upgraded in combination with anhydrous ethanol, toluene, aromatic benzene, xylene and a class of stabilizing and water repellent chemicals, all in a critical range of content. Its synergistic content provides a resultant product that is usable as a compatible additive for lead-free gasoline; it is extremely low in cost, and does not require any engine adjustments or fuel line protection measures; it may be provided with either a so-called regular or 'MID' grade octane rating.

Fuel extender

A homogeneous combustion engine fuel extender fuel formulation has been provided for blending with gasoline as a relatively inexpensive substitute therefor in an amount of not greater than about 50% by volume. Although employing ethanol and naphtha, it is formulated in such a manner that disadvantages of naphtha and ethanol as used alone have been avoided and that gasoline containing the extender will have substantially the same working characteristics as commercial leaded and unleaded gasoline, requiring no changeover or adjustment of engine components when used alternately with 100% commercial gasoline. Basically, the formulation involves a critical solution content of an aliphatic naphtha, ethanol and a higher alcohol.
