We found the non-ethanol fuel in Virginia, North Carolina, South Carolina, Georgia and Florida (and in marinas and airports). We went from 3.90 a gallon here in West Virginia, down to 3.29 a gallon in Georgia.
I noticed that Murphy and Patriot stations seemed to have a good bit of the "pure fuel". It seemed that going up hill under full load that the rig "felt better" with pure fuel.
Some interisting facts about the loss of MPG and HP with ethanol here:
