On the road. Had oil changed in Wichita. Pulled a sample and sent it to Blackstone Labs.
Lab results caught up with me in Arkansas. Currently in San Antonio.
Aluminum, iron, molybdenum and magnesium content were also up (31, 96, 57, and 1069).

This was the second oil change on the truck. Oil, Rotella T-6, had 7,000 miles on it. Truck had 12,100 at time of change.
Keeping a close eye on oil level. So far, no discerenable increase in level.

And if this wasn't enough to keep my mind occupied, the truck was broken into night before last, while parked in the Airport Hilton Parking lot. They used some sort of pry tool in the door lock, based on the mark on the bottom of the key hole, and bent sheet metal...insert tool, press down hard. Open door and select from a variety of goods...

Any thoughts here? (About the oil issue)

You should not have greater than 10% in 7,000 miles unless you idle all day.
I've never heard of this number with the 6.7L.
7% is where you need to be concerned per one of the engineers who used to post here.

wow...look at post #8 in that link.

that was 100,000 miles ago

 

Wow that is pretty high. I've only done 2 UOAs on my truck and they were both at .5% I'm really curious if this is accurate. It seems everyone else is seeing much higher. Is there anyone more reputable for analysis than Blackstone? I like how they work I just question the accuracy.

 

My aluminum and iron are not as high as yours; but, my molybdenum and magnesium content are right in line with yours on my 10K and 15K changes. (50, 56 Moly; 1048, 1190 mag) I think it is just the Shell T6.

I had fuel dilution of 3.5, 2.5, and trace at 5K, 10K, 15K oil changes.

I am awaiting my first Blackstone. My 20k oil change with 10k on it, Rotella T6. I have very low idle hours on my truck. Over 700 operating hours and only 120ish idle.

Someone should start a 6.7l Oil Analysis thread so we can all add to it and compare and discuss.
