I have done 558 klms in a week in my fg xr6 turbo. Taken it to work twice into ipswich and down the coast. I have gave it a few good kicks and the first tank full the computer said it averaged 9.4 ltr/100 klms. The range function says that I still have another 125 klms left. On another note I have a ba none turbo ute for work. I average 8.4l/100klms
