The composition is not fermentation derived. The composition is devoid of methanol, chlorine, copper, sulfur, sulfates and phosphorus. The composition has a pH of 6-9.5. The composition has a total acidity, as acetic acid, of less than 0.01 wppm. The composition is derived from the hydrogenation of acetic acid. The composition is present in the ethanol/fuel blend composition in an amount of 2-98 vol.%, and the fuel is present in an amount of 2-98 vol.%. Preferred Components: The fuel comprises gasoline, diesel fuel (both preferred), ultra low sulfur diesel in an amount of 95 (preferably 85) vol.%, kerosene, jet fuel, biofuel blends, Fischer-Tropsch derived fuels, other fuels derived from petroleum or non-petroleum feed stocks and their blends. The fuel denaturant is natural gasoline, gasoline blend stocks or unleaded gasoline. The gasoline is present at 90 (preferably 15) vol.%. The isopropanol is in situ formed. The acetic acid is formed from methanol and carbon monoxide, where the methanol, the carbon monoxide, and hydrogen for the hydrogenating step are derived from syngas, and the syngas is derived from a carbon source consisting of natural gas, oil, petroleum, coal and/or biomass. The isopropanol present in the ethanol composition is in an amount of less than 850 wppm. The n-propanol present in the ethanol composition is in an amount of less than 270 wppm.
