First full tank I've put through it, 1.9 tdi engine with about 130k.

Full tank no venting/over filling at all got me 640 miles then the low fuel light came on. I hit 500 @ 1/4 tank left, so I knew I could get 600!
I bet with the extra fuel of venting I could hit 700 before the light comes on no problem.
Who knows why anyone would buy anything but a diesel, this is very efficient and its virtually stock.
