Mobil1 tri-synthetic formula 15w-50 
Mobil1 tri-synthetic formula 0w-40 
Valvoline Synpower full synthetic motor oil 5w-40 
Castrol Syntec 5w-50 
Castrol Syntec 10W-40 
Castrol TXT Softec Plus 5w-30 
Shell Helix ultra 5w-30 
Shell Helix ultra 5w-40 
 
My twin cam Harley takes 20w50, lots of chrome 
polish and someday, 1st place! Daytona (bike week) 
in 29 days. I don't think I will see many MLs 
unless there towing a Harley. And I can bet the 
bike is worth more than the ML.

With the temps. that you folks have in the winter, my guess would be the Mobil1 tri-synthetic formula 0w-40. I would consult your service dept. Your miles also are a factor!

the blokes in my car club, MBCA, rave about the fine virtues of Red Line, at only about 10 bucks per quart, I use it. Good stuff.

No, it's pretty much the same. However, some dealers may also use some sort of Euro-blend 5W40 oil, which is also acceptable. If you want to know exactly what goes into your vehicle, it is better to bring your own oil, which is what I'm doing at Service B in a couple of weeks time. Already have my 8 litres of Mobil 1 15W50 from Canadian Tire ($24.95/bottle, IIRC).

http://www.whnet.com/4x4/oil.html scroll down until you see the lists under the MB Sheet Numbers. Choose your favorite brand in a weight which has a viscosity no lower than the lightest recommended oil which, I think is, Mobil 1 0W-40 In terms of the original list sent out by MB, Castrol Softec and Shell Helix are not available in the US.

Drew, excuse my ignorance but is that $24.95 per quart?! ALso, I currently have a blend (Quaker State 4x4) in mine. If I go full Synthetic, should they flush? (got this whitish build up on the inside of the oil cap as well).

It's $24.95 per 4 litre bottle of Mobil 1. No, there is no need to do a flush or anything. The white stuff is usually caused by blowby.

Its also cheaper than way too. My dealer charges 8 or 9 bucks a litre for mobil synthetic oil. Its cheaper to bring you own!
