My TJ-VRX Auto gets the following:
Avg Fuel: 14.5 L/100km's
Distance per tank: 450km's
Amount of fuel filled when light comes on: 60 litres
Avg Speed over that tank, aroune 26km/hr.

I am always in 50/60km zones, car never travels over 60km/hr.

I guess if I drained the car to truue empty, and filled up 69.9 litres, then I'd get 500km's Range.

Car is fully serviced, its drank like this since purchased at 90,000 km's.

If I drive in sports mode, and keep car out of 5th gear, my average has been 13.7
