Fuel ethanol is made unfit for drinking by adding a small amount of a noxious substance such as gasoline. Ethanol is blended with gasoline to produce a fuel which has environmental advantages when compared with gasoline, and can be used in gasoline-powered vehicles manufactured since the 1980's.

How is ethanol used?
Ethanol is used in the manufacture of drugs, plastics, lacquers, polishes, plasticizers, and cosmetics. Ethanol is used in medicine as a topical antiinfective, and as an antidote for ethylene glycol or methanol overdose.
Why is ethanol not used as fuel?
Pure ethanol – 100% ethanol or E100 – could theoretically be used to power cars, but generally isn't, for numerous reasons: Ethanol is bad for cold-starting, because it doesn't burn as quickly as gasoline. (It has a higher octane, if you're interested.) Pure ethanol would be useless as fuel in the winter months.
How is ethanol used as a biofuel?
Much of the gasoline in the United States contains one of the most common biofuels: ethanol. Made by fermenting the sugars from plants such as corn or sugarcane, ethanol contains oxygen that helps a car's engine burn fuel more efficiently, reducing air pollution.
Can ethanol be used in petrol engines?
Ethanol fuel is a biofuel used as the primary fuel or in the form of an additive in petrol-powered engines. ... The United States of America (62.2%) and Brazil (25%) are the top two producers of ethanol in the world. Fun Fact, the 1978 Fiat 147 was the very first production car to run on pure ethanol fuel.
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. ... Deffeyes also says that despite the fact that it's a good fuel for burning, ethanol is actually quite inefficient when its production is taken into account.
Can ethanol replace diesel?
Ethanol is known to be an acceptable fuel for gasoline engines because it has a high octane number [13]. Pure ethanol cannot be used in diesel engines, but it can be used by in blends with diesel fuel.
Is ethanol more fuel efficient than gasoline?
Ethanol contains about one-third less energy than gasoline. So, vehicles will typically go 3% to 4% fewer miles per gallon on E10 and 4% to 5% fewer on E15 than on 100% gasoline.
Is there ethanol in diesel fuel?
The power produced by diesel fuel and regular gas
There are many reasons why diesel is more powerful than gasoline. ... Diesel fuel does not need Ethanol, an additive that increases efficiency. While diesel fuel is highly efficient for use within trucks and heavy machinery, it is less effective in automobiles.
How do you make ethanol fuel?
Most ethanol in the United States is produced from starch-based crops by dry- or wet-mill processing. Nearly 90% of ethanol plants are dry mills due to lower capital costs. Dry-milling is a process that grinds corn into flour and ferments it into ethanol with co-products of distillers grains and carbon dioxide.
Is ethanol fuel better for the environment?
Overall, ethanol is considered to be better for the environment than traditional gasoline. For example, ethanol-fueled vehicles produce lower carbon dioxide emissions.
Can I use ethanol fuel in my car?
Most cars today can run on ethanol gas blends up to E15 (15% ethanol) and on non-ethanol gasoline. And flex fuel vehicles can handle up to E85 (85% ethanol) without a problem. This isn't to say that there isn't a kind of gas that IS bad for your car.
Can cars run on 100% ethanol?
Most cars on the road today in the U.S. can run on blends of up to 10% ethanol, and ethanol represented 10% of the U.S. gasoline fuel supply derived from domestic sources in 2011. Some flexible-fuel vehicles are able to use up to 100% ethanol.
What does ethanol do to engines?
— Corrosion: Ethanol can contribute to corrosion of fuel tanks and other components, and the risk is even greater with small engines with aluminum parts. — Clogging: Ethanol can loosen debris in the fuel line that leads to clogs.
What is a disadvantage of ethanol?
The primary disadvantage of ethanol is that it requires cropland space in which to grow. Because it is derived from corn, we take up lands that could be used to grow food for ourselves or for livestock and use it grow a fuel product instead. Even in the US, 1 in 5 children live in a food insecure household.
Is ethanol a green fuel?
Ethanol is a renewable fuel made from various plant materials collectively known as "biomass." More than 98% of U.S. gasoline contains ethanol, typically E10 (10% ethanol, 90% gasoline), to oxygenate the fuel, which reduces air pollution.
