Rebel,

Thanks for the feedback! I'm glad to see copper finally hit the single digits.. it was high early on, then it was stuck around 10 ppm for a while - seems to be a characteristic of these engines..(??) All the other wear metal levels have been good..

Good point. The TBN of the previous sample shows 11.3 @ 7485 miles. I don't see any make up oil. Must have been some make up oil put in to get the TBN that high. Maybe PS Diesel Oil Extender ?!
 
You guys are good!

… Yes, As Savvy suspected I did add about ½ qt of Power Service Diesel Lube Oil Extender.
