A diesel is most efficient at it,s torque peak. With my Cummins that is 1600rpm, which translates (with my current tires and gearing) to 63 mph. My mileage is slightly lower at 60 or 66 mph if it is dead calm wind. Add all the variables, wind, traffic, grades, driving style..... and just appreciate having your home with you.
