Comments from Blackstone: CHARLES: Oh, copper, why do you increase like that? It came back up in this latest sample, and though it might just be something we have to learn to live with, it could potentially show a problem (especially with iron somewhat elevated). It's possible we're still seeing some lingering wear-in metal, but that's not going to explain the increases. For now, we'll just see how it trends in the future. Potassium was high, but without much sodium, we doubt it shows coolant. It could be related to the EGR, maybe a flux compound. The TBN was strong at 6.3.
Sorry-Unable to provide a better copy. I scanned to a file on my computer and the copy was very good and then used the RV.Net photo posting link to move to my post. The copy did not come over very well. I downloaded as a PDF, deleted my name, address and phone number but it will not open on the RV.Net photo posting link. It will open if I do not edit the original email. I can provide a good copy if anyone has a tip on how to post from my email I would give it a try.
Larry: Silicon was 31 first oil change, 13 second oil change, this oil change is 9
Rotella T 15W40 is the only oil used.
