My 2002 VY Holden Commodore uses half a tank of fuel to travel 100 km to work one day a week, which is about three hours of driving. Is there a problem with the fuel system or is this normal?
It does seem excessive, but first you should actually measure the fuel consumption so you really know what it is doing. Going by the gauge is no real indication of the consumption. If it is using half a tank for 100 km, then have it checked out; it could be a faulty oxygen sensor.
