He uses a frother to mix it up and comments how much it foams up. Last time I checked a frother is made to introduce air into a fluid. WTF

Makes you wonder how some m156s with 90k miles have cams that look brand new and cars with 40k miles that need a whole top end done.

My experience is different My first C63 had 150k miles and I used ceratec. The lobes and buckets looked perfect. It's the same with my second C63 with 60k miles. Both driven daily or at least every other day.
I think it comes down to how long the car sits in-between drives. It's usually the intake cam lobes and buckets which start to go first. That makes me believe the oil film isn't solid enough when started.
I have used ceratec or some other moly additive in all my engines since 2000 and never had an issue.
Makes it hard for me to believe that the oil geek really has enough data or examples to sate that all oil additives are bad.
There are plenty of other "experts" out there who would promote additives.

If what one has been doing successfully to prolong these engines especially with regard to cylinder bore wear on the m157 and the earlier M278, I’d keep doing what you’re doing.

A local shop had a sale on driven oils so I picked up a case for the next change in the m157. It just has strait motul right now. So will be a nice comparo.
