You have to be outa your tree to change the oil yourself. What does the dealer charge an out-of-interval service?
What is going to happen when you waste an internal component at 25k and the service rep realizes you were in there monkeying around yourself? On top if that, you documented it on the internet.
You paid $40k plus for a new car...if you are that concerned about the oil, have the dealer do it and document it...in todays warranty world, paper is more important than parts...
