Does this tailpipe pic tell you anything about the health of the engine? It's the 6.0L Escalade in my signature.

not really

Mufflers do rust over time. The inside of an engine typically doesn't because of all the oil going thru it and not being open to the elements.

It tell me this:if soot isn't going in the exhaust .then it stay in the engine and this means soot is being powder coated where it can inside the engine .

You have no idea what your talking about, The Catalytic Converter takes care of what little soot a gas engine creates.....

To the OP, Your LQ9 6.0L will probably outlive the truck it powers.

Tells me you backed into something! Our Nissan and Toyota are so clean you can't even get a smudge on your finger.

Seems to be double-walled? Wonder why.

Tells me I have a relatively sooty, unsophisticated exhaust system. But I knew that.

Mine has some cement and melted beer can inside it though, which is some comfort.

The manual says 91 octane or better so I've been running premium. That would really be nice if I could. Consumes 1/2 qt oil during the OLM OCI which is +-6000

I can see it is very clean, some cars have exceptionally clean exhausts, other like mine are absolutely black and sooty inside but that's carbed and burns oil...
