I have wondered about this myself...
I never got so far that I actually ran out, but last week I drove about 40km on the TripF counter (about 300km total since last fill) and I could only fill up 11.1 litres after that.
I usually drive very economically, so that the onbord computer says 3.9 l/100km, and when I calculated it myself I got around 3.6l/100km (dividing the nuber of liters the gas station claims by the kilometers on the trip counter).
I think the reason could be that in the hole where you fill the tank, there is quite a long piece/tube going down into the tank about 4cm. Is this meant to be filled to the top? Because I just fill until the gas is just at the bottom of this piece, could be that there are two more litres at the top of the tank? What is the purpose of this part?
Not sure if that explanation is understandable at all though...
