If the car is not telling you to add oil, I certainly would not add oil! MB repeatedly cautions you to avoid overfilling, and warns that doing so will cause engine damage which will not be covered under the warranty.

Best Diesel oil is Mobil1 Truck and SUV 5w40 (its Delvac 5w40 but with a yellow top and sells for cheap @ Walmart)
if you do not want to use that one, use reg Mobil1 0w40
if you think the oil is low since you do not have a dip stick, take it into MB and ask.
