It depends on what brand. There are several spec oils in various viscosities.
If it's Mobil1 that is *not* spec oil. Check it yourself on Mobil1's web site. If that's the case you need new oil...and a new "mechanic".

5W-40 is what I use. Made for diesels and works like a charm in our trucks. No muck and I stopped using oil.
Not sure what MB says to use now...I think it's either 0W-40 or 5W-40. I like Rotella...but Mobil 1 is spec.

I totally agree with the above fully synthetic 5W40 is perfect for diesel engines. There are many brands that are suitable just make sure it meets the current mercedes specification MB229.3/MB229.5 (MB229.31/MB229.51 if particulate filter fitted)

@ almost 230000 miles on my ML 320 now I think 5W-30 or 10W-30 Mobile 1 is good. That's what I have been using for years and my engine still runs perfect and uses only about 1 quart every 10000 miles... I get whatever Costco has on hand at the time...
