Thank you for the replies and the info therein. This is out first hatchback but prior to that, we had an Explorer and a Corolla wagon. Way back when, we also had a Dodge van complete with front air dam, fender scoops and the interior was fully carpeted

None of them were as noisy as the Rogue. The tire issue has caught me by surprise re: noise. We have always run on Michelins. That's most likely what we'll have as of spring, 2012. As for the gas gauge, I've been keeping track.
After taking delivery: 4th quarter, 200km; 3rd, 100 km; 2nd, 100 km; filled up before empty.
Second tank: 4th quarter, 240 km; 3rd, 80 km; bottom half still to go.
