Gas Miliage

[BikrMan]

I am just curious what kind of miliage people are getting on a new F-150 5.4?
I am getting about 13.7 -15.0

[Texan]

I'm averaging 13.75. the best I've gotten is 14.5. Truck has 1,500 miles, I'm hoping for some improvement as miles increase.

I am happy to report to you there is hope for your truck. Mine has a little over 11,000 on it right now and I have been able to get 17.45 @ 70. I also have 3.73LS witch kills any hopes of going much higher. But who cares? I love how strong this truck is. Without the addition of the electric fan, I could not get above 16.
