I am a former mazdaspeed 3 owner and when I went e85 on that car my tuner said that virtually any car without flex fuel can run about a gallon or two of e85. My main reason for wanting to do this would be too lower the possible knock retard when going wot or just spirited driving. Any thoughts or recommendations would be appreciated! My car right now is a completely stock single cam ka with a hks catback
