Distance to empty

[bluey]

You were ripped of mate; you paid for 82L of fuel but in your tank had less than 82L. Petrol station operators are cheating. Buy your fuel somewhere else.

But the expansion tank holds up to an extra 10L. I got 53.7L in the Polo supposed 45L tank after ventectomy.

Main problem is the fuel gauge and trip computer don't know that there's extra fuel in there. Distance to empty stays static until the fuel level starts moving.
