The funny part about the E85 (and others) is they tell you how much cheaper it is to buy per gallon. They TOTALLY forget to tell you that your MPG will suffer and it actually is MORE expensive to use in the long run to the increased amount your car will consume.
I looked at running my last blower car on E85, but the added fuel upgrades and cost for my use wasn't worth it at all. I'll keep burning dinosaurs for now.
Only time I used e85 was in a chevy malibu. Price was about a third and I got less than half the mpg. If I had to do any upgrades to run it, it would not have saved anything. Add in that 14g or whatever size gas tank isnt going to get you far and I wouldnt bother. I wouldnt spend the .74 either for non ethanol either, maybe if it were 93 octane since thats the only fuel that doesnt make my rx8 backfire
