well driving back from brissy to darwin, sitting on 130km/h (120 buy gps) i got 580km out of the tank, that is it as in the car stopped at that speed from when the fuel light came on we got another 80km's before the car ran out! that's with the boot chockers 2 adults and 2 kids and about 150kg in the boot!
extremely happy with how the car went on such a long drive! The car still runs way to rich, the whole back of the car is yellow from over fueling, and believe with a powerfc and getting it tuned for economy at 80 100 and 130 that it would be even better.
