Anyone had their oil analyzed at Blackstone Labs?

I was wondering if anybody here has used this?

I was thinking of sending a sample from my 260E to see what they say out of curiosity?

I have been using Mobil1 Delvac 15-40 diesel oil in my M103...Would they think that is odd or would they know this is a recommended oil to use?

I did. It is a pretty good deal. They give thoughtful comments. It told me my 10K interval is OK.

I just ordered a kit. thanks for the intel

I have; I love their services. It's a good way to see the inside of an engine.

Yup all the vehicles get it once a year. Very personal service with "non canned" comments.
