Hello all!
Just wanted to upload my recent UOA on my duramax truck with 8,000 miles on this sample with around 210,000 miles on the truck.
As you can see from my previous reports this is the first report that showed some titanium. Blackstone never commented on this as its not alarming, but I assume its an additive with the new CK-4 S/N oil?
A side note.. they had the wrong oil listed on this report (mobil delvac 10w30) hence the reason for the comment about viscosity being high for this sample. This oil was the last sample sent to them some time back. This is indeed 15w40 oil. I am still running this batch. I mainly pulled a sample just to check on coolant contamination which luckily is not an issue for me. I expected nothing but a great report back and that is what I got!
I read a lot about folks concerned about CK4/SN oil with the reduced zinc, but I have zero concerns for this in this application.
Happy reading oil guru's!!
