Why is ethanol a good replacement for gasoline?

A gallon of ethanol contains less energy than a gallon of gasoline, resulting in lower fuel economy when operating your vehicle. The impact to fuel economy varies depending on the energy difference in the blend used. … Ethanol also has a higher octane number than gasoline, which provides increased power and performance.

Can ethanol replace gasoline?

No, says geologist Ken Deffeyes. In fact, even though it makes a better-burning fuel, he says it’s a net negative as far as cutting gas prices goes. … Ethanol manufacturers end up competing with the food market for the corn or sugar that’s necessary to create ethanol, so it can actually raise prices, says Deffeyes.

Why is ethanol bad for engines?

— Efficiency: Ethanol-blended fuel’s lower energy efficiency may reduce fuel economy of your engine. — Stalling: Ethanol can cause engine stalling if the water in the ethanol separates from the gasoline and floods the engine. … — Clogging: Ethanol can loosen debris in the fuel line that leads to clogs.

What are the pros and cons of ethanol?

Ethanol. Pros: Reduces demand for foreign oil, low emissions, high octane, and can potentially be produced from waste materials; existing cars can use 10-percent blends (called E10), and more than 8 million cars already on the road can use E85. Cons: Twenty-five percent lower fuel economy on E85 than gasoline.
