just went about 15mpg+ (including doing a few, well a lot of donuts in the parking lot at work ) so probably a bit more than that
I got about 120 miles out of a quarter tank (full to 3/4). Not too bad for a 5.4L 4x4 with snow tires in freezing cold conditions.
I usually get around 15 city and 17 short highway trips. When I go from memphis to Nashville I get around 16.5 on the way back, mostly down hill I get 18 or so.
mpg sucked and then got my edge and was reading 15-16mpg....changed tire size to correct speedo now runnin level 2 im avg 17-18
