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.
I agree. Although when most people say they get ___ on the highway, they mean what their computers instant read out states as they are going down the highway and not end of tank hand calculated numbers. I can easily get this going down the highway at 70 mph on a flat surface, but that does not mean it is a true number I would tell everyone I get. I prefer quoting real world hand calculated numbers.
Besides, every vehicle I have ever owned has had the computers mileage at the end of every tank 1-3 mpg higher than what my hand calculated numbers have been. The only time it is really close is if I am on a long trip with few starts/stops, but the more I start/stop the truck the greater the difference between hand calculated and the computer mileage becomes.
Possible true on some trucks or cars but my GMC is set for 50 miles mostly and sometime 100 miles of testing. So yeah if I was set on instant for mileage okay but I for one am not.
