U.S. retail gasoline fuel prices will be equal to or greater than 4.50 USD/gallon on some date between 06/01/2008 and 12/31/2008. The national average prices, which are aggregate regular grade gasoline (including reformulated) prices across all regions of the U.S. (surveyed and calculated by the Department of Energy), will be used for this claim as the "U.S. retail gasoline fuel prices". The nominal prices calculated by the Department of Energy will be used in this claim without further adjustments.
Currently, the price information can be accessed online: http://tonto.eia.doe.gov/oog/info/gdu/gasdiesel.asp
If the DOE changes its methodology in determining the prices, the new DOE-modified prices will be used for this claim. If such modification results in changing any of the past prices within the above time frame to be nominally at or above 4.50 USD/gallon, the claim will be judged TRUE.
