Abstract
Abstract Hydrocarbon fuels heavier than gasoline may be extended by addition thereto of ether or ester fuel extenders, soluble in the hydrocarbon fuel, having a molecular weight of about 65-200 and characterized by the presence of at least one methoxy group or ethoxy group. The product is a single-phase mixture which is free of methanol or ethanol.
