M1 0w 40 -- cheap and readily available and MB approved!
M1 0w 40. Approved by MB for all diesels without particulate filters....pre-2007. Easy to get at Walmart and cheap.

7.5k interval/ 1 year (whichever comes first) with normal driving....W115, W116, W123 and W124 with diesel engines. W211 OM648 vehicles can use this with 12k intervals (1 year). Again under normal driving conditions. More frequent changes...you are just doing unnecessary work and wasting resources.

0 weight for starting is great in very cold climates. 40 weight is ideal for all but hottest climates (seldom seen consistently in US).
