my trip meter on my Contour said 666km when I got in the car this morning on my way to work (although I don't remember if there were partial kms on there).
Oh and by the way, my gas light turned on at 700kms later on. I could've added 50 more kms before I REALLY needed to fill up, but I was right beside a gas station.
Gotta love the 4 banger's milage (and summertime).
