So the OP gets 10mpg on E10 and over 16.5mpg with no ethanol. Even considering the lower energy content of ethanol, that doesn't add up. 10% ethanol should not cause a 65% drop in mileage. And the stoichiometric ratio is not that different that stock injectors can't handle the difference when using higher blends of ethanol.

Found one 10 min away only problem is its 4.20 a gallon e10 is about 3.90 currently so we will see if the mpg boost will be substantial enough to keep using it

So typically I get about 200 miles to a full tank (20 gallons) and my idle RPMs are about 1200 (I know, high) in my 1992 4.0. On my last fill up I put ethanol free gas in the tank. I have slightly over a quarter of a tank left and I've gone 250 miles and my idle RPMs have dropped below 1000. Holy ****.
I can get 90 octane non-ethanol "recreation" gas across the street from a Sunoco here in Florida
