"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!
