However, the fuel systems of cars, trucks, and motorcycles sold before the ethanol mandate may suffer substantial damage from the use of 10% ethanol blends. Flexible-fuel cars, trucks, and minivans use gasoline/ethanol blends ranging from pure gasoline up to 85% ethanol . By early 2013 there were around 11 million E85-capable vehicles on U.S ...
Some flexible-fuel vehicles are able to use up to 100% ethanol. Since 1976 the Brazilian government has made it mandatory to blend ethanol with gasoline, and since 2007 the legal blend is around 25% ethanol and 75% gasoline (E25). [7]
Ethanol fuel mixtures have "E" numbers which describe the percentage of ethanol fuel in the mixture by volume, for example, E85 is 85% anhydrous ethanol and 15% gasoline. Low-ethanol blends are typically from E5 to E25, although internationally the most common use of the term refers to the E10 blend. Blends of E10 or less are used in more than ...
REC-90. Brighton, MI Sunoco Price sign advertising availability of Rec-90 Gasoline. REC-90 is an ethanol-free, 90 octane unleaded gasoline blend designed for use in recreational/marine engines which can be damaged by the ethanol found in other gasoline blends. It is also usable in some aviation engines [1] and automotive engines, though it has ...
In the aftermath of Hurricane Katrina in 2005, the price of E85 rose to nearly on par with the cost of 87 octane gasoline in many states in the United States, and was for a short time the only fuel available when gasoline was sold out, but within four weeks of Katrina, the price of E85 had fallen once more to a 20% to 35% lower cost than 87 ...
A supply shortage took place for several months during 2010 and 2011 and prices climbed to the point that ethanol fuel was no longer attractive for owners of flex-fuel vehicles; the government reduced the minimum ethanol blend in gasoline to reduce demand and keep ethanol fuel prices from rising further; and for the first time since the 1990s ...
The amount of ethanol used in the United States is also limited by the number of Flex Fuel vehicles available which are capable of operating on ethanol blends as high as 85% (E85) and the relative pricing of E85 as compared to regular gasoline (E10). Other alternative fuels may have higher functional "blend walls".
In the U.S., most consumer goods bear pre-tax prices, but gasoline prices are posted with taxes included. Taxes are added by federal, state, and local governments. As of 2009, the federal tax was $0.049 per liter ($0.184/U.S. gal) for gasoline and $0.064 per liter ($0.244/U.S. gal) for diesel (excluding red diesel). [152]
