I think Mobil 1 0w40 is the correct oil, but anything that it 229.5 approved.

Thumbs up

IMHO, providing you are using the same oil, the differenece between 0/40 & 5/40 is insignificant....and you will find some dealers use one & some the other.
Cheers, Pickles.

Went to my dealer recently to ask. He said MB use to recommend 0W40 but now recommends 5W40. He said 0W40 was still fine but they use 5W40 now.

Guys, AMG Private lounge answered this question: 5W40.

Lifters are prone to bleed down and 0w40 is too light at start up, making the condition worse.

Go hard if you want to use 0W40, but the suggested oil from the horses mouth is 5W40 and has been for years now.

This is true but also depends on the weather of your region. Read this for more info.

It's hard to find 5W40. Shell makes it but I could only find it at my dealer.

And here's why.

I had to jam this down my dealers throat before they caved. EVEN after providing the post by AMG on the lounge.

Mobil 1 Formula M 5W-40
cSt @ 40ºC 79
cSt @ 100ºC 13.2
Viscosity Index 168
http://www.mobil.com/USA-English/Lub...a_M_5W-40.aspx

Mobil 1 0W-40 Value
Viscosity, cSt (ASTM D445)
@ 40º C 75
@ 100º C 13.5
Viscosity Index 185

Benz dealer sells Mobil 1 5-40. Thats what I use. Also manual calls for 0-40 or 5-40 for the m156 engine.
