Drive train, fuel, suspension, steering & brakes / Re: Engine Problems + Excessive Wear on Rockers = OIL!

Modern oils for modern engines such as a 0W-20 for a modern Mercedes is generally less than 800.
The only relevant MB operating fluid specification that is of ANY concern for us, possibly, is 229.1. The other ones mentioned are for more modern cars after the year 2000. Simply of no concern or significance for a Pagoda.
There’s ONLY one Mobil 1 oil with the 229.1 approval. It is their FS X2. 5W-50. Since it is the only one of Mobil 1’s offerings with this approval and it is 5W-50, I would consider it a special oil. Anyone is free to make their own judgment.
I too, I have a Metric Motors rebuild although mine is 25 years old and the whole zinc issue was not yet figured out at that time. Of course the oils were older then too. Note that the oil that Metric recommends is a 5W-50. If I wasn’t using Mobil already, I’d probably switched to that Castrol! So the oil that one of the most highly respected engine rebuilders for Mercedes-Benz engine recommends is indeed a special oil…
