I get around 15.8 mpg doing 75-80 on the highway with my 5.4L

When I picked up my truck it said average 9.9mpg I then reset the calculator and have put around 3K miles on it. It now reads 15.3mpg average

I was able to achieve 15.9 mpg (instant) with my new 2012 before traffic came to a stop and blew it. It took me 30 miles at 55 MPH (YUK). That will never happen again.

I tried driving for mpg to start with and I was averaging 13.1 and then I got sick of driving 60 on the freeway & never getting in it. I average 12.6 now driving it like it should be driven. Smiles Per Gallon
