I used E85 in my truck for two complete fill ups.
There was a drop in perceived power, but it wasn't bad at all unless your a racer. My actual mileage dropped 2.2 mpg.
There was a $10.80 per tankful price difference, so after the mileage is figured in the E85 saved about 90 cents per tankful.
If your hauling or pulling a load, regular 87 is the way to go. If your commuting or you want to give non-US countries less money go with the E85. Do not think you will be saving yourself money by using it, you won't. But it is fun to use the yellow hose for fill ups and you get strange looks from other motorists.

Hey, that's 90 cents you wouldn't have had otherwise! I wouldn't throw it out the window, so why not save some money, even if it is less than a dollar?
Besides, two tankfulls probably is not enough for the computer to fully adjust.

Really, as far as fuel system compatibility is concerned, any vehicle that was certified to run E10 will work with E85. It's methanol you want to watch out for. I have yet to see any proof that E85 is more corrosive to materials than E10.

Well I save $3 on each tank, it’s not much… but it’s still $3. I think I’m going to use it when I’m at a station that has it; problem around here is that all the stations that sell it are on the edge of the city, except for a greenway that has I priced so high it’s more expensive to run anyways, so you lose the savings if you have to make a special trip to get it.

now, don't take this the wrong way but nobody in their right mind is going to take their $35,000+ truck that isn't set up to run on E85 and go and do it...if your truck isn't E85 compatible how about you run E85 for the next 6 months only and report back to us with your findings???

However, nobody in their right mind should tamper with their new truck in a way which would harm their warranty...
