I'm not sure. I'm going to research it some more when I'm ready. Even if you're not going to run e98 you can always use it to correct a lower ethanol content you buy from the pump......
Or cut it with 100 unleaded and make some stout E85. The pump stuff is cut with the crappiest gas available. I was able to go pretty far with pump E80 though.
Dave,
You could run as low as E70 and mist it down with alky if needed. Im keeping my alky system on the car and will eventually play with it burning E85.
