I don't believe that NASCAR is using ethanol. I know F1 race cars use it.
Three uses for ethanol are fuel, alcoholic drinks and an antiseptic.
Ethanol.
Indycars and F1 cars use alcohol-based fuels. NASCAR uses high-octane gasolines.

Alternate fuel source, if you get 70% Ethanol and 30% water w/w you have a very good broad spectrum anti- bacterial, ethanol is used in labs as a solvent to dissolve desired compounds from different materials
1) If you blend enough gasoline with ethanol (E85) the fuel will be compatible with the seals in most fuel systems and it can be used by any vehicle. 2) Gasoline acts as a denaturant and allows the producer to qualify to pay no liquor tax on the ethanol he produces. 3) Gasoline is a well proven fuel and readily available for blending. 4) As a denaturant the gasoline renders the ethanol inedible and unpalitable, and much less likely to be diverted to other food uses. 5) Gasoline is more dense than ethanol and increases its energy value per gallon.
It depends on what you are traveling in. It would also depend on if you are figuring what is given off or what is used to create this fuel to go with it. Straight gas uses less carbon than does gas with ethanol if you figure what is used to make the ethanol.
No. Nascar only uses Chevrolets, Fords, Dodges and Toyotas.
YES, like all ethanol/ alcohol products with at least 50% purity. [F+]It's toxic even at 5%/E5. Ethanol/ Alcohol is a HYDROCARBON. It is C2-H4-HO1 typically. Christian religions have banned it's consumption from the Puritans to Bejamin Franklin's Quakers. Alcohol/ Ethanol was banned in the 1930's in the Usa. Chevy/GMC uses Ethanol/ Alcohol in their E85 flex fuel hydrocarbon cars.
Almost only Exxon, pretty much every other one uses 10%
Ethanol has two main uses. People drink it to become intoxicated (mildly or severely), and it can be added to gasoline to make a fuel called gasohol. It can also be used as rubbing alcohol although isopropyl alcohol is preferred if only because it is not drinkable.
Regular UNLEADED gasoline, up to 10% ethanol. Does not require high test, not made for E85 fuel.
