One more thing on fuel that contains 10% ethanol are you guys seeing a true 10% gain in mpg when you use fuel that's 100% gasoline?

No, Ethanol is a fuel. Therefor it will burn just like gasoline, but has a higher octane than gas and it will hurt fuel economy. Not sure how much less "powerful" it is vs gas but it is less, but more than none.
