I typically see 14-16 mpg on my daily commute, which is about 1/3 traffic, 2/3 highway. I've had several 17 mpg tanks with mostly highway, nothing over that so far. I think there is better mileage to be had, the hill country does seem to eat into it. Towing my boat I see 10-11 mpg, but a lot of that is 75-85 mph speed limits, so I can't expect much better. I don't speed, but do try to run the speed limit. Always hand calculated, the EVIC is typically1 mpg optimistic. Overall, mileage isn't down too much over the '03 I traded in. I can't remember if I updated my signature, 2016 tradesman 2500 ccsb 4x4, about 12,200 miles.
