I had a flex fuel engine in my 04 suburban (ford innovation...yeah right). E85 has less energy per gallon than regular fuel. It is a bit cheaper, but for that you lose mileage and power. Also, here in Denver with the altitude and especially when it's cold in the winter there are starting problems. E85 is by its nature high octane and twice while in cold snaps the truck would not start with E-85 at 5am....had to wait for the temp to come up.

I would love to run bean gas personally, but it's my opinion that the compromise of being able to run one or the other makes E85 a pain. The engine needs higher compression to take advantage of the E85, and that would make it E85 only...which the public is not ready for. So, I won't be doing the E85 thing again...at least while living in the cold.
