Guess I better start watching my 23
Had the oil changed earlier at 5000 than recommended at 7500 miles. It’s at just over 9 k now.
Mine sees mostly trailer miles but I did just get back from a 1500 mile trip with no trailer. Was pleasantly surprised with gas mileage running 75-80 most the time. Got around 16 running empty and probably 14 withe about 2600 lbs in the back on the return trip averaging 15 all around. My route included I 80 across PA so it was far from flatland.
That’s about as good as a diesel empty . Good as a 6.7 ford anyway. | 
GM 6.6 gas engine using oil?
