Best Tankful Ever!
 

28.18 MPG on a 100% Interstate run between Nashville TN and Indianapolis.

I ran the air conditioner about a third of the way. I used the cruise control to hold 1700 RPM except when manuvering through traffic.

All I can say: seriously impressive.

Amazing results for an F-350 :thumbup:

Really pushes me to work harder on my mods. The highest I've managed to pull is 25.6MPG on something almost half the size.
