I must really have a heavier foot than I realized. I consider my driving style very tame. I do 80-85 on interstate, but mostly follow the speed limit around town. No heavy acceleration. My driving is probably 60% interstate / 40% city. I run on 93, mostly costco brand, but occasional non-tier gas. I have the procal tune for the last 500 miles.
Just hit 2k miles, avg 15.8 MPG.
Lower than I was hoping for, my Tacoma with heavy steel front and rear bumpers, skids, and overlanding gear in the bed got about the same. I still love the truck though!
