2 weeks ago I acquired a small supply of E0 and got the front air dam tore off during that trip. I stuck the stock tune back on the engine but kept the improved shift points and lockup settings and went at it. I had 1 gallon of mixed E10/E0 left so I figure it is all good. The first tank was 25mpg. The second will be empty this week if I drive that van every day. I have enough gas left in the barrel for one more tank after this one hopefully.
I can say that on my cars and most older cars I have messed with, it seems like 20-25% mileage drop with E10 is pretty consistent.

Thanks for the input Rick. I'm struggling to understand what is different about the 6.5 liter that it should not suffer as badly on e10 however. I think it is hard to avoid e10 and if there is a solution for older cars then that would be most beneficial.
here's some info on converting an engine to straight ethanol, wonder if any of these apply

mostly having to do with adding more fuel, but some discussion about advancing timing and using 10:1 compression, hotter thermostat, fuel warming, etc.
