I am on my third tank now. I usually start looking for a gas station when the light goes on (two bars left on the gas gauge). I have been getting around 340 mile on each tank in mostly city driving.
katmar you should typically get around 350-400 miles per tank unless you do a lot of city driving like sdpadsfan. My wife's last tank got her 29.5 MPG and about 390 miles with one bar of gas remaining.
Well petrol for me, as that's my only option here in the states for the moment, but I am crious about diesel as well. I've read and watched a couple reviews recently where they went about 450 miles on a (petrol) tank, which is impressive! Of course that was basically running it until empty...
