As @UG_Passat stated, per all the literature I've read, its the compound that gives VW508.00 it's green color.

Here are the numbers MB229.71 has to meet as compared to VW508.00. Lubrizol doesn't have more than the HT/HS requirements for BMW LL 17FE
(incidentally, MB229.71 can be had at your local WMart in EDGE EP (Gold Bottle).

No purpose. Lab says 'wear metal' which I think is true.
Are you sure? It's just 2 ppm. That would hardly cause any visible coloring.
This is supposed to be a M1 ESP x2 VOA (VW 508 00) and it does say 0 ppm V:

I can't be completely sure but i'll try to dig up where i read it. You're right though, that seems like very little, but it is the only oil i've ever seen it in (for whatever that's worth).No purpose. Lab says 'wear metal' which I think is true.

EDIT: It appears that everything i read is assumption and guesswork. My apologies.

I wouldn't say that, as a transition metal vanadium has several salts that can be used as dyes. It seems reasonable.

Yes, but 2 ppm is still very very little (too little I think). Vanadium is also used in some steel (tools).
I too was wondering for some time what exactly the 'VW 508 00 dye' is. I just know they use to put some Zirconium in as a tracer, but that probably has nothing to do with the dye. Or does it?

Hmm I thought it was vanadium?

I'm pretty sure it's Zirconium. Unfortunately most OAs don't list Zr. Will post it if I can find a source.

This thread talks about zirconium as a marker.
Zirconium is the marker in VW508.00. It is a fuel economy oil

Great looking report for a FF at 10k. Looks like the 508 is agreeing with the engine.
Why would the Lab mention “flagged data may be from an overhaul” on a 10k analysis from a 10k mile 2021 engine??? 
Seems like such a silly comment to make… unless it’s mostly just copy / paste wording they always use.
Looks good for a 10k run on the factory fill. I would have dumped it at 1,000 miles if not sooner. Haha.

Thanks for finding those posts on the market being Zirconium. I got both elements confused. Your "likes" refreshed my memory.
I plan to sample in or around 5k miles since that will be well after winter and a long drive we have planned. Just to see if it's the same.
M1 esp x2 0w20 508/509 approved and about 75ppm
And 300 ppm boron
Well I've been referencing this chart and I see now it doesn't even have moly on it. Doh!
So if considering two 508 00 approved oils the one with a molybdenum compound is automatically better?
Hard to believe Shell HUP would fail to meet spec and is actually that low HTHS.
Must have been an odd batch or a botched test, as they'd not have been able to get the approval at 2.3 HTHS.
Not sure what the "copper corrosion test" is either but the Mobil lube did not do well at it.

Agreed, with that low of an HT/TS it qualifies as a 0W-16.

I'd almost bet Aral SuperTronic LL IV FE and Castrol LL IV FE are virtually the same. Both are BP brands.
