I pay $30 to have my analysis done, that's with Blackstone Lab
Never heard of the service being offered over here, although it might be something used by motorsport geeks.
I can change the oil in my vehicle for only a little more, so don't really see much gain except perhaps as a diagnostic tool....As I said, I can see it perhaps being a benefit to a large commercial/fleet operator where oil changes would cost substantially more.....
