How much cheaper is ethanol than gasoline?

Fuel Prices

This makes E85 32% cheaper than gasoline. So when you factor in the cost of E85 and the mileage it yields, the cost for E85 is less than gasoline. Even in the worst-case scenario, when E85 reduces your mileage by 25%, you can save about 7% on fuel.

What is the downside of ethanol gas?

The disadvantages of ethanol and other biofuels include the use of farmland for industrial corn and soy growth, rather than for food crops. Also, biofuels aren't meant for all vehicles, especially older vehicles. There is some resistance from the automotive industry when it comes to adding biofuels to the market.

Higher-ethanol blends still produce significant levels of air pollution, reduce fuel efficiency, jack up corn and other food prices, and have been treated with skepticism by some car manufacturers for the damage they do to engines.

Is ethanol cheaper to produce than gasoline? (2024)
Can a car run on 100% ethanol?

However, most cars don't run on pure ethanol – in fact, running on higher than 15-20% ethanol concentration can cause engine damage because the engine has to be adjusted to account for the differing combustion property of that concentration.

You can produce your own ethanol for an ongoing cost of less than $2 per gallon. If you grow your own corn, you can distill more than 300 gallons of ethanol from 1 acre of corn. If you drive less than 10,000 miles per year, you could produce all your own fuel from 2 acres of corn — and, granted, a lot of labor.

How long will 10 ethanol gas last?

Ethanol-Blended Gas: Up to 3 Months

“Regular gas,” meaning most gasoline sold at gas stations around the country is ethanol-based gas, which is typically 90 percent petroleum and 10 percent ethanol. This type of gas has a shorter shelf life than pure gasoline and typically only lasts for up to three months.

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.
