what oil grade is great for 70000 plus miles?

Before the current nomenclature was instated, MB followed sheet 21x.x( generic SAE/API and ACEA specs), which later turned into 22x.xx. One of the things you've missed about this whole conversation is the difference between then and now, which is that oil manufacturers didn't have to pay MB for certifying their oils to go on the approved oil list.
If you need a math tutor there's craigslist.
Also, what's the purpose of this discussion?No one asked about lubrication for old cars. I said 0W40 Mobil1 229.5 is good for the M278 and the M273, your responses made me non the wiser. You are forgetting the purpose of this forum, it's not made for bickering.
One report I remember a few years ago showed high silicone levels for an 02 crown Vic with some bolt ons and aftermarket tune. 102k miles. Ran perfect no noise etc. Also showed an increase in aluminum. I couldn't figure it out until I found a correlation of silicone to plastic. The only plastic I could think of was the plastic pads on the cam chain guides. I pulled the cover and sure enough one was worn into the plastic and the other was through the plastic and had just started into the aluminum. Tragedy averted. I've always been an advocate of getting an analysis at intervals.
The owner's manual is online:
