The 6.7L Cummins in my all-steel, 3/4-ton 4x4 Ram got a calculated 23.4 MPG on a 1,000-mile all-Interstate highway trip from Denver to Chicago (not towing!).

Yeah terrific. I have 3 words for mpg claims like that. Tail-wind and downhill! Oh and you were probably slugging along in the right lane at 62.4 mph. Love these mpg claims.

Have you ever driven I-80 and I-76 between Chicago and Denver across Illinois, Iowa, and Nebraska? Do you really believe that it is all downhill and that there was a continuous tailwind? I used that example because it was the longest trip I have taken in that truck without towing my trailer.

But, on a shorter trip without the trailer last winter, we drove the Ram 2500 diesel on a week-long trip from Las Cruces to Big Bend NP and back on a variety of Interstate, US, and state highways, plus through the Davis Mountains and on park roads. We drove at or above the speed limit on all those roads and our average mileage for the entire round-trip was 22.7. And we certainly didn't go downhill and have a tailwind in both directions!

I track the mileage in the Ram because I have had four gas pickups, including two Fords, before this diesel and I am constantly amazed at how much better my mileage is than in any of the others.

If you are regularity getting 22.7 MPG in any 6.7 diesel you are very far out of the norm. You either have a very special, almost one of a kind, truck, or you drive very conservatively.

If it is the former, I’d keep that truck for a long time. If it the latter, you would likely get 35-40 mpg in a 3.0 diesel.
