So what you are saying the the manufacturers minimum spec isn't good enough to protect the engine?
From your statement MAN does not exceed OEM minimum?
Yet the OEM honors the engine warranty anyway. I would like to see some proof of that.

Not true. If you buy a brand new BMW, MB, Audi, etc you could remove the filter at the first OCI and dissect it to compare to another one after being the run the same amount of time/Km.
Ditto one from the dealer.
All three of these manufacturers are OEM suppliers.
