I somewhat disagree with your viewpoint. If M-B lists the oil as a tested & verified oil for the respective specification (229.3), then it is a recommended oil by M-B for use in the engine. However, I do agree that just because the oil is on the list, it may not be a brand type &/or grade that I would use.

And like so many things about this car, there are multiple lists available (see attached file) for reference. So there are a multitude of oils that meet M-B's specification for these cars & M-B's recommendations aren't consistent from one list to another. So one might question the source of the information in just about any of these lists.

One will also notice that the attached states that the paper element oil filter is acceptable for cars using the FSS oil monitoring system. But most of us use the fleece filter element anyway. And I thought the fleece element was specifically recommended for the SRT-6 motor (someone can correct me on this); the paper filter element was acceptable for the NA motor. So if the SRT-6 uses the same FSS oil monitoring system, why isn't the paper element filter still a viable choice? That's always been somewhat of a puzzle to me.
