Just wanted to share a recent experience with you in regards to grades of gas. My 2011 Ecoboost Flex has a little over 3000 miles on it. I admit it's not even completely through the break in process. I have used 93 octane from day 1 until my last fill. I had a wild and crazy day and went with 87. In all my previous 93 tanks I would get 16 mpg every tank. Just wanted to let the world know that under the same driving conditions and habits I am easily over 18 mpg with the 87 grade. (This is a combination of highway and city driving)

Interesting... usually the opposite is true! Normally your MPG goes up a bit with the higher octane.... have you done more than one tank with 87?
