This is the only UOA I've done so far on my 2021 Audi S4 Premium Plus with the EA839 3.0 "hot-vee" single turbo (not supercharged) v6. I did Audi care for this vehicle so this is VW/Audi 0w-20 508.00 spec oil. This is driven mostly highway with some high-speed rural back road driving mixed in and almost always in a spirited way. This engine with the factory sport exhaust sounds just amazing so I love listening to it sing. I continue to run 10k OCI and once dealer oil changes are over will switch to Valvoline Euro 0w-20 that meets 508.00 spec. This engine seems to like it just fine!

I don't see a lot to complain about with this analysis. The oil and engine appeared to have handled this OCI with ease.
Not that Blackstone is trustworthy in this regard.
A 508 oil must be pretty stout to handle a turbo that well for that long.
It does seem to hold up really well, which is good because it’s not cheap! Best deal I could find was Valvoline at about $8/qt delivered.
I’ve seen others say that VW brand 508 from a dealer is pretty reasonable.
