Even if you wanted it, fuel ethanol wasn't available in the U.S.

With the end of government contracts to produce ethanol and farmers exporting a big portion of their harvest to foreign markets, ethanol production plummeted. Cheap foreign oil was plentiful, making gasoline a bargain. Retailers stopped offering ethanol altogether, and it became virtually unavailable in the U.S. from 1945 until the late 1970s.
