Jens,

9 mpg?? Is that city & highway normal driving? Have you looked underneath at the fuel lines & gas tank to see if there are any cracks or dripping from pinholes? Something is definitely wrong if your mpg is that bad.

is the 9 MPG based upon the meter readout from the trip computer, or is it a MPG calculation based upon the actual amount of miles traveled divided by the amount of fuel consumed?
what was the MPG when it was OK at first?
