RE: 6.7
I don't think a short 60 mile drive is long enough to give you a true mpg mileage read out. Was it one way down a very long 6% grade? I've seen my 06 QC 4x4 with 5.9L get 20.5 mpg on a 378 mile trip with 16oz of Lucas fuel additive driving on flat ground and the engine runing at 1600 RPM's. But 28 mpg hand calculated from a 07 Mega Cab 4x4 with a 6.7L engine? I would have to be there to see it as I find it hard to believe a 07 Mega Cab 4x4 with a 6.7L can get 28 mpg at 60 MPH let alone 25 mpg hand calculated while driving it betwen 70 & 80 MPH!
