Gasoline vs Ethanol Calculator
Compare ethanol and gasoline using price and expected efficiency ratio.
This calculator helps you decide which fuel is worth it when you know the current gasoline price, ethanol price and the efficiency ratio of your vehicle. The default reference is 70 percent, but you can adjust it to match your own car.
That makes the recommendation clearer and more practical for comparing gas stations, promos and price shifts over time.
