Do your own research. I owned a 2007 F-150 that was flex fuel. It required severe duty maintenance schedual if you used E85. You used to have to order flex fuel vehicles with that option. They obviously did something different to the fuel system to make it more durable. The forums on the subject concour that they had to use stainless steel to keep corrosion away. Making ethonol is taking corn and making alchol with it. It taks A LOT of corn to make alchohol. That cuts into our food supply because corn is used for so much of what we eat besides other chemicals. Just logic and common sense. There is less BTU's in ethonol. That is a no brainer.
