Yes engines still shed metal and no engines are not built any cleaner than years ago, machining metal is dirty business there is no way around it.
Edit: The old argument "the filter will catch it" is a bit bogus also, there is a tight clearance oil pump before the filter that can get scored by metal particles especially ferrous metals.

This subject is unsettled on BITOG. User Kschachn criticized early change out, but he offers no "published technical justification" for an engine lasting past its warranty period...But Trav is the master. You'd do well to listen to him.

Jim Fitch has published more articles and holds more patents than most BITOGERS have years of education and experience. (beginning with kindergarten). I'm not going to offer further info on Mr. Fitch's credentials. Most people know how to google.

Do whatever lets you sleep at night. Hope you enjoy your new truck.
