Amazing MPG
So starting Monday of this week, my wife and I had to do a 1400 mile trip back down to Arizona. Of course I got stuck driving our SUV and trailer and she drove the Mustang down. To my surprise at 70 MPH we were averaging 28.5 mpg. I am amazed how Ford squeezed so much power out of these 5.0's yet able to give beyond amazing mpg without having to do cylinder deactivation like other companies do to try and get anywhere near that mark. Just wanted to let any non believers be able to believe and say good job Ford, well done.

The 5.0 Coyote is an extremely fuel efficient engine due to its high 11:1 CR and its TiVCT. The two overdrive speeds of the 6L80 and MT82 transmissions also help greatly.
I average approximately 22-24MPG and that includes where I step on it during spirited driving.
My driving conditions are as follows: 50/50 mix of city and highway, mostly during rush hour where speeds drop below 35MPH for over 66% of my driving time.
My rear gear is the standard 3.31:1 ratio, Manual.
During long all-highway trips of 70MPH, I observe 28MPG for the whole trip.
Best observed all-highway MPG on a 100mile trip is 30MPG, but I had to go no faster than 70MPH and I had to use hyper-miling techniques including: stepping on the clutch to neutral on down-sloping grade to drop RPM to idle while getting 70+MPH, not getting off the freeway at all to prevent having to slow down to any speeds below 70MPH, paying attention to weather reports so that I only drove with the wind behind my back.
But doing all that hyper-miling crap is too hard to do, and keeping it to no faster and no slower than 70MPH is equally just as hard.
Even on all-freeway trips where I go 80-85MPH, I still am able to get 24-25MPG average for a trip.

Was that via the on-board or hand calculated? I don't discount your report of 28.5 but it should be stated where that value was derived. The on-boards are TYPICALLY off by about 1.5-2 MPG high.
