Copy and paste from a previous post of mine:
I was really bored and had a full tank of E85 in my car. So, i decided to see how many miles i can go if i baby the car. I drove from West LA to Willow Springs and drove back home and then some trying to maintain 70MPH and staying off boost (my gps says i did 67MPH avg) . The drive to Willow Springs, once you get on the 14N, is a LOT of long uphill highways. So, i was probably boosting anywhere fromn 0-5psi on the long uphill stretches. However, on the way home it was a lot of downhill driving.
I drove until my fuel light came on and drove for 10 about more minutes (245 miles on trip) and i filled up my tank with gas again (12.1 gallons).
According to my fuzzy math
245 miles / 12.1 gallons gas added to tank = 20.24MPG
I probably could've squeezed more MPG if i picked some flatter roads to drive on...and yes i really do need a life
On "normal" driving with occasional blasts down the highway, 15MPG...

When I first converted to E85 (22,000 miles ago) I averaged almost 20mpg 325hp/335tq DynoDynamics.
After installing FP4r cams and some more boost I average abot 17.5mpg or 12 gallons to 210miles. On a recent road trip to the cabin I averaged 19.8mpg at 70mph.

So far, all good for me. No different than driving with gasoline. I really like the idea of E85 because it should keep the cylinder temperatures lower, and its so much more stable against serious detonation. The only issue that concerns me is possible accelerated engine wear due to cold start corrosion or perhaps cylinder washdown. Might not be apparent until 30,000+ miles from now.

What mspilot said.
My car gave me a couple difficult starts in the winter (car would sit for four days in sub zero without ever being started) but it would start. Most mornings it started with an extra crank or two but then it would start right up.
I don't even change my tune on the winter fuels, I just don't get into the throttle as much.

It is my understanding that when running gasoline and you live in an area that adds Ethanol in the winter (i.e. E10), the best thing is to get your car tuned in the winter that way the tune is always safe in the summer.
Conversely, when running E85 and you live in an area that adds gasoline in the winter (i.e. E70), the best thing is to get your car tuned in the summer that way the tune is always safe in the winter.
Obviously getting tuned monthly would also work, but cost a lot more.
