Thanks, Topless. That makes sense. It would also explain the 10% 'increase' in MPG.
Do you have any idea what happens if you try to use that "extra large reserve"? Theoretically, the 'kms to go' readout would be zero. I have read that the car goes into emergency mode when fuel is very low. Do you know if this is triggered by the float?
Sorry for the awkward questions.
