In 2010, the cost of fuel in the US averaged US$3.42, while the cost for E85 averaged US$3.09, or 90% of the cost of gasoline. [21] [22] In another test, however, a fleet of Ford Tauruses averaged only about 6% fewer miles per gallon in ethanol-based vehicles when compared to traditional, gas-powered Tauruses. [23]
As of 2005, E85 is frequently sold for up to 36% lower price per quantity than gasoline. [10] Much of this discount can be attributed to various government subsidies, and, at least in the United States, the elimination of state taxes that typically apply to gasoline and can amount to 47 cents, or more, per gallon of fuel.
Since the 1980s until 2011, domestic ethanol producers were protected by a 54-cent per gallon import tariff, mainly intended to curb Brazilian sugarcane ethanol imports. Beginning in 2004 blenders of transportation fuel received a tax credit for each gallon of ethanol they mix with gasoline.

Ethanol fuel has a "gasoline gallon equivalency" (GGE) value of 1.5, i.e. to replace the energy of 1 volume of gasoline, 1.5 times the volume of ethanol is needed. [4] [5] Ethanol-blended fuel is widely used in Brazil, the United States, and Europe (see also Ethanol fuel by country). [2]
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.
About 90% of vehicles on the road can use unleaded 88 gas, which is being sold in five states for $1.99 per gallon. Last chance to get $1.99-per-gallon gas Skip to main content
One major drawback with corn ethanol, is the energy returned on energy invested , meaning the energy outputted in comparison to the energy required to output that energy. Compared to oil, with an 11:1 EROI, corn ethanol has a much lower EROI of 1.5:1, which, in turn, also provides less mileage per gallon compared to gasoline. [7]
