Thank you for posting all of these UOAs and VOAs, GermanAutohaus. Motul X-cess looks really popular at your shop. Seems to do a good job.

You're very welcome. I'd much rather share the data with the community than keep it private. I'm all for sharing the love and I know someone, somewhere, can find it useful. The X-cess is our standard bulk oil that we use for the majority of our customers vehicles. It's continued to prove its self time and time again as a good long life oil as well as being able to handle some abuse. I want nothing but the best for our customers and using a quality oil as our baseline gives me a warm fuzzy feeling.

Definitely acidic oil but who's to say that's a bad thing? Haha. Perhaps the engine is spotless inside because it has acid flowing thru the passages? Haha.
