IN my diesel trucks I used shell rimula x 20w-50and had no problems Check yourself with the MB service agents and I think that the only oils to see clear off are single grade oils as they do not have the additives necessary for long haul vehicles. An example of this is if you use a multi grade grade oil in a GM 2 stroke ( detroit) they tend to glaze up the bore as the additives prevent proper ring contact with the bore.. However regardless of the brand you will be looking for a viscosity rating for the area you operate in
