Information about this oil:

You'll find this oil at the dealer or directly from your local Mobil distributor. The only spec you'll see on the bottle is 229.51
That spec will maintain your warranty coverage.

Oil in diesel engines is degraded by the same mechanisms as in gasoline engines, but with the additional presence of soot particles, which increases as the oil ages. During usage of a diesel engine, the crankcase oil gradually builds up soot which is a combustion product in the combustion chamber of the engine and which is transferred in small amounts to the crankcase oil. When the soot builds up to an unacceptable amount, say about four percent by mass or weight of the oil, the lubricating quality of the oil is inhibited. Thus, it is necessary to change the crankcase oil whenever the soot content reaches an unacceptable value.
I need to find out more why an oil change every 5000 miles is detrimental to the MB diesel engine.

1) Money. MB makes more if they make the engines difficult or impossible to service.
2) Liability (money again). In the United States of Lawyers MB has to cover itself against ambulance chasers. Product liability suits may be reduced if MB can claim a number of services should or could only be done by their franchisees.
My friend who owned an E55 (2003) had the same experience. He was told by the MB service advisor that if he changes the engine oil before the oil light comes on his warranty is toast.

However, all the dealers are screaming that the Canadian government must tighten the importation of US cars into Canada. The excuses are exactly the same, safety, specifications (stupid things like the mandatory burglar alarm and daytime running lights) and certification.
MB cars of under 15 years old can only be imported if certified by the manufacturers. What a joke.
What's detrimental is changing the initial breakin oil (factory fill) too soon.
After breakin, more frequent than recommended changes are strictly detrimental to your wallet and to the environment.
In any event, those that apply science rather than mythology and old wives'
tales to the subject rely on used oil analysis. Such analysis of oils meeting Mercedes specification consistently shows that oil at 10-13K miles is just fine.
