Is LIQUI MOLY overkill for an E36 "M3"?

Same way. Liqui Moly is often unfairly put down on this forum. The reality is that they own and operate their own oil manufacturing facility and R&D center in Germany, ensuring full control over quality and formulation. While it's true they may not use GTL, they do offer oils that contain Group IV synthetics and esters, as well as high-quality Group III formulations. Many of their products carry approvals from like MB, VW, and BMW. Plenty of enthusiasts confidently stand behind Liqui Moly's products
Putting over way, if their oil products with all those approvals and cost like M1, Pennzoil, or Castrol and available at local WM, they certanly would have good number sales.
But they certanly DOA if there is no FCP LRG and sold for full price
Besides the regular "Synthoil" (which has too high Noack for modern manufacturer approvals) what oils do they offer that are truly synthetic?
a bunch, also all SDS available www.liqui-moly.com
But for my BMW I was considering Special Tec B FE SAE 0W-30 and Top Tec 4210 SAE 0W-30.
Both have 1-Decene PAO 30-60%
Also what you mean by "truly synthetic"? There no group IV only 100% oils commonly available
Vollsynthetisch. The german definition of full synthetic. I did not say 100% group IV.
I didn't know about Top Tec 4210, that's an interesting one. Nothing similar in 40 grade sold here unfortunately.
Why do you care about 40, if HTHS is >3.5 it is all good.
Additionally Top Tec 4210 has viscosity about 11.9. it is a very thick W30 almost 40
An oil that starts at 3.5 won't be 3.5 after abuse. That very thick 30 grade will become a very thin 30 grade.
No it will not
It is bmw long life approved
I personally used LM long life high tech with LL04 approval in my g37 for over 5K miles and sent to BS. The viscosity still was above 11.
That vq37 engine is running hot and known for searing engine oils like crazy.
LM uses high quality Viscosity improvers

There is thickening going on there, or that batch was much thicker than what pds says.
Don't forget, blenders (any) put typical value. Just because that oil starts at 12.2cst does not mean you cannot have batch that has basically 5W40 in it (12.5cst). If it is 12.2cst, it dropped and started to thicken.

Every blender does that except "big boys," and some smaller oil companies who are in the business of drilling, etc. They sell base stocks and additives to companies like Liqui Moly.
I saw similar results after full VW recommended 12 K km OCI in VWs where Viscosity of LM did not drop.
You can enable auto translation and see viscosity check at 3:00
And I assume it is with bad quality high sulphur gas

Wait, is that report in miles or km?

Seems unlikely

4210 has older additive pack, not new additive pack. Group III base stock pack that is common with API SP additives is much better than before in Castrol, Motul etc. which gives them pour point as low as -45c. 4210 has pour point of -47c.
So, if it had 60% PAO, pour point would be somewhere around-60c like it was with Castrol Edge 0W30.
So, PAO is probably closer to 30%, further compromised by not such good Group III base stock.
how do you read that in his UOA?
I don't care.. As you saw from my earlier post LM sells this product in Germany as "synthetic technology". It's no different than M1.

KV100 is too high for that mileage. It probably sheared, started to thicken than. Unless it is km. But if it is km, oxidation is bit high then too.
Also, as I mentioned, just because pds says 12.2cst, doesn’t mean you get 12.2. That is typical value. It could be 12, or 12.4cst.
You are talking about KV100, not HTHS. Your KV100 is thickening due to volatile low-quality bases.
