xcel, I'm sure you drive a little after you've filled up and not just let the car sit in your driveway, right?

My point, as you mentionned, is that most dieselers fill it up to the brim because it's easier and it has no ill effect, that's all.

It was a reaction to some very high mpg results in the database (you those with only 1 tank and it's super high...).

Anyway, an observation more than anything. ^_^
