Do I get to divide my mileage by .85 if I run E85.. I can only get 324 miles out of a tank of that stuff.

it would have to be a miles per dollar calculation, I can't compete with you with super but I can on E85
If you want to bring attention, I highly reccomend talking to the big ALT FUEL community there is tons of support for these events amongst that group..
I'd invite some of the TDICLUB guys to humiliate you. some of them get 800miles on a tank.. but since their fuel is more expensive it might be closer then you think mi/$
and sprinkle in a priui or 3 and it can be quite fun.. I'll donate the new shop as a starting point Ironically enough it's currently a Biodiesel factory. and I intend to have CNG/Ethanol conversions become a major part of my business, since both energy plans have HUGE pushes for alternative fuels.
this could be fun..
