Pure ethanol would be useless as fuel in the winter months. There are no passenger cars designed to take E100 (but some racing cars are) so it could damage your car engine. Even Flexible-Fuel vehicles (FFVs) – which can run on petrol or ethanol – can only take up to E85. 100% ethanol is hard to come by.
Similarly, what year was ethanol first used as a fuel?
Ethanol use as a fuel continued after the tax was repealed, and fueled Henry Ford's Model T in 1908. The first ethanol blended with gasoline for use as an octane booster occurred in the 1920s and 1930s, and was in high demand during World War II because of fuel shortages.
Is ethanol required in all gasoline?
State Laws On Ethanol In Gasoline: Only Seven States Require E10 Blend. Under the Renewable Fuels Standard passed in 2007, the Federal government requires certain volumes of ethanol to be blended into the U.S. transportation fuel supply.
What is ethanol and why is it added to gasoline?
All gasoline engine vehicles can use E10. Flex-fuel vehicles can use any ethanol-gasoline blends up to E85. The energy content of ethanol is about 33% less than pure gasoline. The impact of fuel ethanol on vehicle fuel economy varies depending on the amount of denaturant that is added to the ethanol.
