I've often heard that you should never completely fill your gas tank to the absolute maximum and a quick google search that I did came up with a few people saying something about it causing damage to the charcoal canister. Do modern cars even have these as part of their emission controls anymore?
I haven't been completely topping off my tank, but I really want to start doing it as I think my MPG calculations would be a lot more accurate this way. This would help me fine tune the calibration on my Scangauge and once that is done I really wouldn't need to completely top off the tank anymore as I could then rely on the gauge better.
