My mileage is hand calculated by the way. I don't have an overhead.
I still think that I have something wrong with the truck. Its going in the shop to see whats up next week. Its being very inconsistent and losing mileage. The first tank I did driving it home I got like 16.5. Its been down hill from there. The only good thing is I get 14 towing or empty and being that I am loaded more than empty thats a good thing.
