ABSTRACT:
A spark ignition motor fuel composition consisting essentially of: a hydrocarbon component containing one or more hydrocarbons selected from five to eight carbon atoms straight-chained or branched alkanes essentially free of olefins, aromatics, benzene and sulfur, wherein the hydrocarbon component has a minimum anti-knock index of 65 as measured by ASTM D-2699 and D-2700 and a maximum DVPE of 15 psi as measured by ASTM D-5191; a fuel grade alcohol; and a co-solvent for the hydrocarbon component and the fuel grade alcohol; wherein the hydrocarbon component, the fuel grade alcohol and the co-solvent are present in amounts selected to provide a motor fuel with a minimum anti-knock index of 87 as measured by ASTM D-2699 and D-2700, and a maximum DVPE of 15 psi as measured by ASTM D-5191. A method for lowering the vapor pressure of a hydrocarbon-alcohol blend by adding a co-solvent for the hydrocarbon and the alcohol to the blend is also disclosed.
