Ethanol or grain alcohol, is a slightly toxic chemical compound .Gasoline or petrol is a petroleum-derived mixture.
Gasoline is cheaper to make, uses 1 energy to make and gives 5 energy. Ethanol uses 3 energy to make and gives 2 energy. This means it takes more energy to make it. This in mind I would have to say gasoline is better. Your vehicle requires twice as much ethanol to go the same distance as gas and since it costs more to make, then it will cost more to buy.
