Just filled up and my last tank breaks down like this. 50/50 City/Hwy - 554 miles driven, 30.049 gallons used, 18.437 MPG hand calculated. EVIC was showing 17.9 so I was pleasantly surprised the MPG was better. I'm starting to realize that many of the higher MPG responses on varying forums are likely in flatter areas versus where I live. City driving also affects my MPG more than I thought it would, but at the end of the day, the overall mileage capability of this truck is outstanding. I absolutely love my truck and now if I can find a good local service center.
