The PQ Index provides information about this, if I understand what you mean correctly...

Yup. Its getting to the point you almost need to even order just regular off the shelf products lately. UGHBeen hunting for this oil without any succésReally Hard to find...

Chelation (chemical leaching). I already mentioned this. Esters and AN's, both of which are polar, will liberate material from a surface as they fight to adhere to it (hence my remarks about aggressive chemistry) which in turn shows up in UOA's, which cannot discern between these particles and actual metal. Probably the most common example of this is huge increases in copper from oil coolers showing up as "wear" with oils like Redline, but this applies to other metals as well.
On your 2nd posit, if you looked at @wwillson's filter autopsy, there were visible metal particles. Those are clearly much, MUCH larger than 5 microns, same with much of the stuff you see on a filter mag or magnetic drain bolt.
This reads like you copied and pasted it from Wikipedia.
Edit, found the source:
If you are going to quote something from a 3rd party, please give them the credit for the material rather than blatantly plagiarizing it.
With that out of the way:
Blackstone doesn't provide a PQ index, neither does OAI, NAPA, SPEEDdiagnostix. You can order particle counts from some of these labs, but this isn't limited to ferrous material, it just gives you an idea as to distribution of the size of different contaminants.

You're right, I should have stated that, sorry my mistake, wanted to set the PQ index or the explanation. Despite your description and explanation, for me, an analysis that consistently shows small elements in several analyses in a row is an indication of a small engine wear. You probably have a different opinion on this as well as me too, let's leave it that way 
"It's fitting that ExxonMobil, as a long-standing Porsche development partner, also offers special high-performance oils for the Mezger engine family, namely the Mobil 1 FS x1 5W-50 and the Mobil 1 FS x3 10W-60 (from the second half of 2020). . These revised high-performance oils ensure even better wear protection, very good engine cleanliness and low oil consumption thanks to even better sealing. The focus of the lecture from Mobil 1
However, developer Haris Junuzovic had the Mobil 1 ESP x3 0W-40 with the new Porsche C40 oil approval, which is approved for use in all current Porsche V8 and boxer engines. The outstanding properties of this new development range from optimized friction behavior to even greater wear protection compared to the already very good predecessor product Mobil 1 FS 0W-40. Especially in the area of connecting rod bearings, high temperatures and speeds place extreme demands on the engine oil.
len. Lower fuel consumption has also been demonstrated in numerous engines compared to 0W-30 oil. The risk of LSPI pre-ignition occurring in some modern turbo engines, which can lead to major engine damage within a very short period of time, is eliminated by specially tailored additives. The same applies to the protection of petrol and diesel particulate filters. Maximum aging stability, even when using low-quality fuels, enables extended oil change intervals of up to 30,000 km. The result of ExxonMobil's research and development efforts is a high-tech product that combines outstanding technical properties with fuel saving potential. New and performance-enhanced air-cooled 'Wicked Sixes' are supplied with appropriate high-performance oils in a species-appropriate manner. PC Hamburg would like to thank you for this exclusive specialist lecture."

Thank you for sharing this!
Great. I've got a 25 litre stock of Fuchs Titan GT1 Flex 3 5w40 which carries C40 approval and now I want to throw it all out and stock up with M1 0w40 ESP X3. 
Annoyingly, the Fuchs can be picked up for £34 and the M1 is £66. Huge price difference for two oils with very similar approvals.

How much value is C40 to the vast majority of us who don't have a new Porsche. Both M1 and Porsche have said it is not backward compatible for engines requiring A40 or C30. Surely there must be some technical reason and I am for sure not willing to take that risk given that A40 is already plenty strong.
C40 is a low SAPS ver of A40 and C40 will only be a 40 grade just as C30 is only a 30 grade, and C20 is only a 20 grade. There are probably regulatory reasons for the lack of backward compatibility being that Porsche like everyone else is moving to 20 grades and consequently receiving fuel efficiency credits.
BMW for example is removing heavier 30 grade and 40 grade approval from an engine family which previously recommend them.
Porsche is not moving to 20wt. Their previous oil standard was A40, which were only 40wt, and that continues with C40.
C20 is a Porsche approval. They may not use in in their 911 and HP V8's but it exists.
You said it yourself, we're talking about A40 application backward compatibility. Show us an A40 application that's migrated to C20.
C20 is irrelevant in the discussion of C40 backward compatibility.
If you strictly believe in the approvals then yes, it is not interesting for anyone without a new 911 or 718. Even A40 is probably not very interesting for the majority of BITOG members, let's be honest. Most of the interest is because these oils are also ACEA C3 or A3/B4 and not because there are many Porsche owners here. Since it has API SN+ there's nothing stopping you from putting it in almost any Japanese or American car anyway.
Most value in A/C40 is track test sequence. Other than that, it is nothing special.
You mentioned A40 and C30 (see below). Porsche is unlikely to say C40 is acceptable for C30 because C30 is giving away to C20. That was my point.
first time i read this old topic.
@OVERKILL beside your scientific knowledge in oils, my compliments for your rich vocabulary and use of words.
i wish this oil had bmw approval. why doesnt it? i might cant find still new sp mobil 0-40 but this one i can easily find it near me..price is reachable ,78 euros 5 lt.,10 euros more expensive than normal 5-30 or fs 0-40.
one question though.whenever you guys or some of you ,see viscosity index of 200 you say yikes . is there something i am missing here or isnt it always bad for the consistency quality of engine oils? first time i see it in a mobil oil and i know that mobil is maybe one of the companies that knows why it does what it does.

Thanks.
A high VI tends to point to high quantities of VII (Viscosity Index Improvers), which are not desirable, as they can lead to deposit formation, and the kind used in most oils are prone to experiencing some shear in service, which means permanent viscosity loss.
Yep. The rumor from our MIA friend Argentum was that this oil contains some kind of novel VII that had exceptional shear resistance.

The star VII that HPL uses isn't really "novel", just expensive, lol. And yes, insanely shear resistant.
