So out of pure curiosity, I decided to see how low I could get my fuel tank today. I ran it until the fuel gauge red near zero and also my mileage left panel got to zero, and I still drove it another 10 miles. When I fueled up it went to 13.8 gallons. I have read everywhere that it should be 16.4. So did I really have another 2.6 gallons of fuel or am I missing something here?
