To help motorists understand the cost differential between E-85 and conventional gasoline, AAA also is posting a nationwide, average “BTU-adjusted E-85 price” that accounts for the fact that E-85 delivers approximately 25% less energy content per gallon than gasoline.
According to AAA, today’s nationwide average price of self-serve regular gasoline is $2.811 per gallon compared to $2.334 for a gallon of E-85. Today’s BTU-adjusted price of E-85 is $3.071 per gallon, or 26 cents more expensive per gallon to get mileage equivalent to that contained in a gallon of self-serve regular, according to AAA.
There are approximately 4.5 million motor vehicles now on American roads capable of operating on E-85 or conventional gasoline through the use of flexible fuel technology, and more than 1,200 gasoline stations nationwide are now dispensing E-85 on a regular basis. Most of these stations are concentrated in the upper Midwest near the nation’s ethanol processing plants, but E-85 pumps are beginning to appear in other regions as well.
The data collection and calculations used to derive the prices of gasoline, E-85 and the “BTU-adjusted” price of E-85 is performed for AAA by Oil Price Information Service.
The AAA Fuel Gauge Report Web site lists average daily prices for the nation, all 50 states and more than 250 localities for all grades of gasoline, making the site the most current and comprehensive public source of fuel price information.
