I think TBN starts at 12.9.

SDS does not show full picture. SDS just shows compounds that are harmful.
M1 has around 10% esters in it too.

I agree with Adams355 here. Try Motul 5W40 Sport, 300V or 5W50 Sport.

It was a fairly "normal" run for me this round but did include repeated visits to the local "1/8 mile street racing" event at a local track so probably 2 dozen 1/8 of mile runs. I drive it hard normally. I was surprised too and I know we chatted here about using it, look, it's fine oil and the drop is about what I've seen from some other UOAs for these little tuned-out VW 4 bangers. I just was hoping to see less drop. The iron increase is a bit surprising vs. the trend I have as well but probalby un-related. We will see how the QSUD and M1 5W40 look next!
I drive my cars hard too. That should not be reason. Last UOA on M1 I did, previous version though, in my VW CC KV100 went from 13.5 to 13.3 in 5k. M1 5W30 EP I have in Toyota literally didn’t shear at all in 10k, and I push that minivan to its limits all the time, plus a lot of idling time. So, not sure seriously why such poor performance.
I don't either, no idea. I just think these little VW 4s chew oil I guess?
Wonder if it's just a turbo direct injection thing but hard to say. Seems like my turbo DI M4 / M3 chews through oil too per the viscosity drops in only 2k mile UOA but my turbo DI 4 in the X1 doesn't seem to shred oil nearly as much.
IDK, I always had stellar UOA on CC and Tiguan. But, you have big turbo, so that will definitely make things different.

you could run a straight 30 if its warm enough.
All you VW dudes run higher boost pressures/tunes and ethanol fuels.
Basically. Boost is ~22 peak which isn't crazy at all and I do run E20-ish most of the time.
What do they run stock T? 22psi is up there on E20 especially if its a bigger turbo. Don't usually go much higher than that unless its a built motor build but I don't know the platform well.
I can't even remember..hahahahaha....tuned it shortly after purchase. I *think* about 12 peak new. Stage 1 took that to ~17 then around 22 for the larger turbos from either the GTI or R. Some tuners will get into the mid-20s with a bit more dialed-back timing advance. These engines routinely hold boost up to the high 20s without being "built" - the issue with more boost is the stock fuel system won't handle it.

Yep seen this exact VOA. Yet Boron, Calcium and Zinc seem well off. Wonder why that is.
While we see boron go down in the course of an OCI, Calcium and Zinc dont (not by that much on a reasonable OCI)...
Checked the previous LiquiMoly run and well... it is similar and the Ceratec or the MOS2 additive(forget which) maybe helped slightly.
Would not blame the Mobil that much, you are driving a tuned car fast / drag racing.
Either way, I think the big turbo turned your engine into an oil shredder( viscosity killer).
Cutting some miles off the OCI would be my bet for lower wear numbers.

The formulation could be updated, hence lower ZInc.
The thing is, this is just the OE turbo off the Golf R, so while pushing more than stock even on a stock R, in terms of UOAs etc. I've seen on that platform, the results are similar. What I'm getting at is even stock, these MQB 4s seem to be harder on oil than other engines.

The actual data is listed on the Mobil website, as you can see, KV100 has changed over the course of 4 years, as has flashpoint (439F)
