What Engine Oil?
Me?,.....I don't concern myself with this issue....I just run with what the book says (what the Dealer puts in?).....I think there's a Mobil 1 sticker on the car somewhere.....I've used that on many of our cars....never had an issue.
To be perfectly honest, I reckon oil produced by any major manufacturer, providing it was of the right viscosity etc, would be OK.

My dealer was not aware of oil change to 5w-40.

Thank you very much for your post. This occurs as the automotive fluid standards have changed in the meantime (in May 2008)
AMG recommends the use of the following oils:
- Mobil 1 5W-40 for M156 engine (63er models)
- Mobil 1 0W-40 all other AMG engines (as well the AMG diesel engines that was used for the C 30 AMG)
- Mobil 1 5W-50 SLR engine
Before that change, the Mobil 1 0W-40 was used for the 63 models as well.
We hope that this information helps.

And this is why we don't use 0w40. It's too thin at start up which allows it to bleed out of the hydraulic lifters. Which can cause loud valve train noise and premature wear.
From BISTOG "The greatest confusion is because of the way motor oils are labeled. It is an old system and is confusing to many people. I know the person is confused when they say that a 0W-30 oil is too thin for their engine because the old manual says to use 10W-30. This is wrong."
Here is some very useful oil information.....Probably been posted here many times but just in case....http://www.bobistheoilguy.com/motor-oil-101/
Was at my Dealership yesterday to discuss a few things at which time they topped up the oil in our '12 C63, with 0-40 Fuchs.

I posed the question recently on PL and they responded

The bevo document specs 229.5 for the M156 for every where but western europe
The weight must be 0W40 or 5W40
Is this correct?
There is confusion with some believing only the 5W40 is approved and/or recommended
Is bevo incorrect?
The dealer has been using 0W40 in mine
Dear Ingenieur,
Thanks for your request!
We have checked with our After Sales Team and you can use both oils.
Please take a look in our overall list for the specification “229.5”, where you can find the usable engine oils:

Or simply the engines are not warmed up properly and driven hard when cold?
