The ONLY thing "good" about non petroleum fuel is the fact that it is refined from something beside petroleum. It will never be cost effective in any mileage comparison cause pure gasoline will win every time. It's just the idea that it conserves "real" gas albeit by making corn and sugar skyrocket in price due to scarcity until they get a balance going.
