Yea, and moly...

The question of course is how much is from the oil, and how much is from surface coatings and assembly lube? In the end it doesn't matter the source, but it does argue for leaving the factory fill in as long as practicable to aid break-in. The "change it ASAP" argument just doesn't hold up. A nervous new owner would do themselves well to be satisfied with swapping the factory filter at 1,000 mi and leaving the oil in until at least 5k mi.
