I doubt that this engine had any run in by Mercedes Benz. If it were mine I would fill it initially with a quality non-synthetic oil and do as you said, run it for 20 minutes without load at various RPMs. Then take the car out and run several half throttle acceleration runs and then cruise at speed varying the RPMs again. After 100 miles change the oil and filter and again add non-synthetic oil. Run this oil for 3-5,000 miles driving without restrictions. Then change to Mobil One or what you feel is its equivalent and change every 6 months or 7500 miles.
