The computer counts the number of times the fuel injectors fire to estimate the fuel consumption. It's pretty accurate but not perfectly accurate. I agree on the 17+ gallon tank. You have to consider how much fuel is in the lines and how much you have 'over-filled'.

I have several times driven well past "0 miles to empty" with the most being about 15 miles past that point, yet I have never been able to put in more than 15.9 gallons of fuel.
