"You notice my brand new / rebuilt engine flush procedure?
Amazed to see how much particles are left in a "clean" new engine from the factory."
When I had my brand spanking new 06 5.9 CTD the recomended first oil change was at 1000kms and that they would NOT touch it until that time. If I remember correctly I tried to take it in early and they sent me away. I was under the impression it wasn't normal oil but some sort of conditioner. I guess to each their own, I'm sure they are all different but the guy who sold me that truck was a former diesel tech from Cummins, he seemed to know the engine inside and out. I'm suggesting there may be a reason for doing it as they suggest and following their recomendations. It may also be worth noting that they also told me NOT to tow for the first 1000kms, I assume until after the first oil change. I still recall the sales guy looking at me when I told him I did and saying.. "I like your confidence!". My 09 1500 doesn't have a HD applicaiton maint. schedule in the book, I'd assume the OP doesn't either. I believe my CTD did. I may be off on the 1000kms but pretty sure.. It was a milestone!
That is a special break in oil.

Most car makers no longer use this technique, of a special (often single weight) oil that lets everything seat and smooth itself.
The problem, after that oil is flushed, is that metal particles and casting sand etc. keep shedding for quite some time.
