While raw data such as presented above is extremely useful, there are are several other aspects that should be taken into account.
1. The age of the car---- cars more than 10-15 years old may have a recommended service schedule that is geared to the oil technology available at the time.
2. The normal usage of the car- frequent stop start / cold journeys will shorten the useful operating life of any oil be it mineral based or the latest synthetic [ altho obviously the synthetic will be better in this respect]
3. Cost-- over specifying an oil to somehow derive "more benefit" is false economy. Low saps/ ash oils such as MB229.31 and MB 229.51 are only of benefit to diesel engined cars with DPF's [ diesel particulate filters] for example.
For older models my rule of thumb is- use the grade of oil Mercedes recommended when the car was in production- if they thought it was adequate -- it was. Stick to Mercedes recommended service intervals for oil and filter changes taking into account the car's normal operating conditions.
If you want to pamper your pride and joy change the oil and filter at shorter service invervals rather than go for some esoteric extended service interval 21rst century oil that costs a fortune and spend the money you save on some other aspect of maintaining the car' s health.
