Question for those using E85. I bumped into a fella at the track that started sharing his experience with E85 in a purely street application. He told me that he switched back to gasoline because of the poor mileage and overall cost of running the E85 fuel. What has been the experience, fuel mileage and overall cost wise, of those of you using E85 for the street? Never mind the performance side of it, just the economics of burning E85.
