To bad E85 isn't a legal fuel but I guess the local convenient store pump specs still wouldn't be consistent enough to pass fuel check. The other thing you might think about is putting a separate 5 gal fuel cell in just for spec fuel with a three way valve on it to switch between fuel tanks. You would still waste some getting the old fuel out of the lines but you wouldn't have to mess with draining the street stuff out.

I'm seriously considering seeing what I can do to the wifes old daily driver. Its a 97 Grand Prix 3.8 supercharged. Natural AF car which is a 13.85 index. Not sure what it would take to get it there. Hmmmmm
