> yes you can… special carb set up for e85 from jegs or summit… but your fuel milage will go down about 20% it takes more 85 to do the work of regular 87 octane

i heard its closer to 40-50%… i went to a tech seminar at the GS nats about e85…actaully let me rephrase that… you’ll need twice the fuel to do what gosoline does…thats the down fall but the upside is that the octane is better
