As I recalled, one of MB's TSBs gave instructions (to a Tech, can you believe it?) as to how to check the engine oil level properly. Another TSB was to revise the amount of oil required for oil change by 1/2 qt. I do not remember what year or model the TBS is for. It sounds like MB is serious about having proper oil level. The bottom line is: between the marks and not overfill. I think on the mark is okay.
