Importance of first oil change in new equipment

The owners manual states that you must change the oil and filters at the 5 hour mark the first time. Is it because there is metal in the oil from the rings seating? That's the only reason I can come with. What's your thoughts?

Yep, just the insides wearing smooth. That break-in oil will have sparkles in it.
Prolly the reason I shudder to even consider buying a used piece of equip...did the original owner do it right from the git-go?

Letting it go until 50+ hours with the break-in oil still in it...would knock a lot of potential hours off of an engine...and it would consume oil the whole way I'd imagine.

PLEASE correct me if I'm wrong, sirs.

You are exactly right. Usually if you look closely at the oil it will look like metallic paint from the tiny metal shavings in it.

For me it happens at the 5 hour mark, 20 and 50, then every 50 after that. Napa oil filters and rotella-t 10w-30 oil.
