I hope you realized that this is political question.
While the MB have FSS set at 10-13,000 miles in US, the same models are allowed to do 40,000 km in Europe. In Germany oil changes are dictated by engineers, in US by lawyers.
That said having lot of experience with oils I would say, that would I be in Europe, I would advise to drive it the listed distance with no big worries . Just add refreshing shoot of detergents with oil addition.
Since I am in US, I have to say "talk to my lawyer"
