Hi Benengel,
there are too many variables to get an accurate distance. Your driving style, the direction of the wind, if any, hills or flat ground, towing or not towing, city or country K's?
We had the fuel light come on about 70 Km's south of Coober Pedy on one trip early in our ownership of a YD25 D22. We limped into Coober Pedy going real slow for that last 70 Km's. I was letting it free wheel on downward slopes. I'd be surprised if I'd get that around town, or in the hills!
