Thanks Quazacolt for introduce oil test
Confirm the Subaru used liqui moly as it is having highest moly in the report

Oil review: ADDINOL SUPER LIGHT 0540, used for 9600KM
» Click to show Spoiler - click again to hide... «
Hey huge thanks for willing to perform UOA and sharing to all of us.
Is it ok for me to also add in to the first page for easier references/access?
As for your first report, is it for Subaru XV? I'm not sure if they ever used Liqui Moly, thought they just used Motul, maybe recently switch to LM.
FYI that amount of Moly is actually low and majority of mainstream oils have similar, if not even more amount of molybdenum
The second Audi sample looks good too.
Though the viscosity seems more towards a w50 (even though from your mention the model being "super light and 0540 seems like an indication it is definitely 5w40 lol) engine oil which is really thick and may not be within Audi's specifications?
9600km was pretty impressive as well though it would be better if there's TBN to see how the additives held up and that may open up for longer OCI possibility.
Can ignore if you have no desire for that, considering it is an Audi and reliability can be a question mark. Or, I'm overthinking and it's non issue to you as you have other cars in case the Audi does face issue
Nevertheless, thanks for you contribution to the community!

I think the below part is the most important as it show how "dirty" of the engine and possible of failure of any parts.
Upper part is some addictive used to protect the engine and should no fall to certain lv (?)
Do the oil check as I purchase it as recond car and Subaru is 2nd hand car.
Next check will be both car transmission oil
I'd say all is equally important as you get to know what oil is good and what oil is only marketing. Able to tell wear metals is also early detection of potential problems within an engine without the need to open it up. As I've always provided analogies akin to humans performing blood test as opposed to an actual surgery.
