Living here in Iowa, E85 is shoved down our throats. It is subsidized by the government making it slightly cheaper than regular gas. I have read quite a bit about this fuel. Performance of most cars is the same as with gas. Mileage is a different story. Most cars using E85 get 20% to 25% less miles to the gallon. 3 weeks ago when unleaded was selling for $3.49, I checked and in my town E85 was selling for $3.14. Looks good to the consumer selling for 35 cents less a gallon. But, taking the mileage difference into account, you have to buy more E85 to go the same distance you would get with unleaded. In other words, in order to be competive with unleaded, E85 should be selling for $2.85 a gallon. At this price, you can go the same distance for the same cost. So, you are paying a preimum for E85. Also, if you convert your car to use E85,will it void your warrenty?
