I have an ecoboost, but heck i have had non turbos all my life. Hell there is a non eco ford edge next to my truck. Not once have I ever even considered e85 in any of my vehicles. I see what damage a small % of ethanol does in our gas to small engines,atvs and boats. Doesnt make a difference to me if I had the 5.0 or ecoboost...no e85 for me

It's a damn good fuel system cleaner and helps remove carbon from the valves, heads, and pistons. Running it the tank before an oil change would be a great idea. This was one of the deciding factors in me upgrading my injectors so I could run e85 with the blower.

Most folks posting about E85 have no freakin' clue. They love mentioning stoich but they only do so because their favorite website mentioned it. The truth is E85 is being used in motors not designed for it. If you were to build a motor that can take advantage of E85 the MPG's will be better. Compression needs to go up but to a level that makes 87-91 unusable.
E85 also fluctuates on the actual amount of corn in it. The lowest it can be to be labeled E85 is 51% ethanol, though most run in the 70% range plus the 2% gas already in the ethanol before it is mixed prior to distribution. Also, summer blends have less gas than winter blends. It doesn't take corn out of the food supply either. It does produce both fuel as well as livestock feed.
Is the process perfect? No, but without continued research new innovations will never be discovered. Areas that use to be limited to what crops they could grow now grow switch grass which can be used to produce fuel. Algae can now produce biodiesel and with further research in motor design, one day you will see a motor that can take advantage of E85 and it will get similar MPG's to regular gas.

It was 50-55 cents cheaper here but since gas has fallen the prices are now even.

Ethanol won't ever get the same amount of fuel economy as pump gas 87,91,93 as seen here
E85 requires the use of 40 to 50 percent larger fuel injectors, to compensate for its 40-45 percent increase in fuel demand. The change in stoichiometric AFR from 14.7:1 with gasoline to 9.76:1 with E85 is 66 percent, but the resulting flow needed is only 40 percent greater, due to E85's higher density than gasoline

The energy content of a gallon of ethanol is 76,100 BTU and 114,100 BTU for gasoline. Even taking 15% of the fuel being gasoline and 85% being Ethanol it's not possible for E85 to have a higher energy density than gasoline, ever.
Not sure where you got that figure for E85 but it's incorrect.
Or, are you referring to specific gravity? In that case it is denser, but Ethanol has a much lower flash point as well.
E85 has a higher energy density than regular gasoline? Since when?
