National Survey of E85 and Gasoline Prices

10/1/2008

The objective of this study was to compare the retail prices of E85 (fuel containing 85% ethanol and 15% gasoline) and regular gasoline nationally and regionally over time for one year between July 2007 and June 2008. The United States was divided into six sampling regions. A sampling plan of the approximately 1,200 E85 stations that were operating nationwide at the time was devised to allow statistically significant regional and temporal comparisons of the data to be made within the limited data collection budget available. Results indicate that the price of E85 appears to closely track that of gasoline, and the gap between E85 and gasoline appears to widen somewhat as the price of gasoline increases beyond about $3 per gallon.
