It seemed to happen after the recall in the PCV.

After about 300 km I only have less than a quater tank of gas left. Yet the fuel economy has remained consistent. ABout 12L/100km.

I have filled up a few times and did the math:

number of litres to fill divided number of kilometers

the answer matches the displayed economy.

I have never had a fuel guage go bad.:crazy:

hmmm, that is odd...
we had a gauge go bad on our old Ford, but it went bad the opposite way and would just run you out of fuel.
