I never really got an answer from the dealer, but what is the suggested break in period for the 6?

hmmm...i would guess that it is something like 1000 or so miles?

thats what I would have guessed, thanks.

It's 800 miles, it says so in the manual

I have a 03 6 and I gave it 1000 miles. They say about 800 but if you drive hard like I do I would recommend 1000. Also use Mobil 1 full synthetic as soon as possible, it's the best.

Actually, they say exactly 800 miles, but I wouldn't recommend driving too hard even after 1000 miles. Work up to hard driving. And be sure to run the car through the full RPM range throughout break-in. Mobil 1 is a good idea too, but you may want to wait until the second oil change (assuming you do the first right after break in) to switch to a full synthetic.
