Question didnt your dealer offer the first oil change for free? That way they can get you in the door.
P.S. there are more then just piston rings that need to be broken in and the way that is prescribed through those post it doesnt do anything good for any of those other parts. Just some food for thought. This is just my recommendations.
Dealer's first oil change is at 3 or 5k mi i forget no way am i letting the oil i have in there now sit in there any longer.
