i've ran an almost full tank of E85 on a few occasions, and the result is usually that the car is doggy until it gets up to temp but more powerful once it gets warmed up, and the mileage falls down from 18 to 13.
but, on one particular tankful of pretty much straight E85- i filled it all the way up as soon as the "low fuel" light came on, which is usually about 2 miles before it dies- i got 24mpg on a 130 mile interstate blast at 80mph with 2 passengers with their luggage packed in the trunk and the AC blowing ice cold. that was the best i've ever seen with that car.
but i generally try to keep it about 50% E85 mixed with 50% 87 octane- which gives me the same fuel mileage as straight 87, with the increased power of E85.
