Here is the problem I see: As far as I know, in the US, there are only two types of M1 5w-40, and it has not been stated which is reccomended (although it does not matter, which I will explain):
Mobil 1 Turbodiesel Truck 5w-40 (no MB passenger car approvals)
Mobil 1 ESP Formula M 5w-40 This carries ONLY the 229.51 rating, which is ONLY for use in diesel models with DPF. MB has stated that 229.x1 oils are only to be used in diesel models with DPF, and all other models are to use 229.5 oil. I am sure that if you look in your manual, you will also see that you must use a 229.5 oil.
There are two possiblities for this statement regarding 5w-40:
1. They are speaking about a different oil not sold in the US
2. MBUSA made a mistake, which happened before with 229.51 oils.
The best way to figure out which oil is best for your car is to use your brain: The cars require 229.5 oil that have a viscosity rating higher than -30, which leaves only those three oils that are -40 vicosity 229.5 oils:
M1 0w-40
Valvoline Synpower 5w-40 HST
Lubro Moly 5w-40 Synthoil High Tech
There is nothing special about M1, they just have a very valuable marketing agreement with MBUSA, I have never seen a Mobil product in a German service center.
