Doug B I recently took a highway trip. From Klamath Falls, Oregon to Biggs Junction, Oregon - over 270 miles. My MPG gauge showed 41.2 MPG. I had done this before, and had seen what I thought was an exaggerated reading. This time I also wrote down the mileage on the odometer, and checked it at fill-up. I got 42.9 MPG. I have a 2013 "S" model with a manual tranny - completely stock. Is this even possible?
