With my daughter flying in for the Thanksgiving holiday I put on a lot of highway miles and was able to get an idea of fuel mileage on the new truck. 500+ miles of hilly Ozark terrain @ 60-70 MPH limits. The dash read 27.6 but hand calculation was 26.2. Not too bad on winter blend fuel. The amazing thing was that with all of the long, steep uphill grades the transmission never shifted down. My '17 5.0 6 speed would always downshift 1 and sometimes 2 gears on several of these hills even with 3.73 rear gears.
With the trip meter being 5.3% optimistic is there a way for the computer challenged to calibrate it.
