Well I did so good for the first 200-250 miles but I could not drive like and old man anymore.
This last tank 26.6 MPG keep in mind I have 33x14.5x15 trusx tires and stock 4.10s

I am curious at what I will get with my plowing tires 234/75/15

The first half tank via the fuel gauge was 240. Before it hit the half tank mark
