Oil Recommendation W212
Discussion
I seem to recall my W211 takes various grades, and there are recommendations depending on local conditions.
There are Mercedes oil specs that you might find more readily in your manual or on a sticker somewhere, or even written on a previous service invoice. These are 3 digits, a full stop, and a fourth digit. Like 299.3.
These correspond with the more commonly known specs, just Google it when you find a likely candidate.
Also if you have an old service invoice look to see if there is a part number for the oil as that serves the same purpose.

I find the Eurocarparts search function a bit hit and miss - currently sitting with a brake flexi hose that in no way fits my car!
Try Opie Oils, they have a similar reg checking system and used to do a Pistonheads discount. You might find it narrows it down further to a specific weight/grade/type.

First and most important question, does your car have a DPF?
Not sure when they came in on your model but would suggest it's possible.
If it does you must use an approved low SAPS oil with the spec ending either xxxxx.31 or xxxx .51. I think they were 229.31 or 229.51. I think 229.52 is backwards compatible to the earlier 229.51, but check.
The ones ending with just xx.3, xx.5 etc are for petrol only.
Viscosity in most, if not all (certainly every MB handbook I've seen) basically allows various viscosities depending on ambient temperature. Generally, the newer MB diesels use 5/30, but some garages will use 0/30, and 5/40 is generally fine. 5/30 tends to be used to reduce internal friction, decrease mpg (v slightly).
