Maybe it's the "new math", but I just filled up. They few guage was near the bottom, my Nav. screen said that cruising range was 65 miles, yet the tank only took 12.65 US Gallons. I even topped it off. I thought the capacity was 17.1 US Gals? that would mean I have over 4 gals left, which even at my average of 32.1 MPG, I should have had a cruising range well over 100. Is cruising range really accurate?
