Dealers also use vacuum extractor for all MB cars.
No mess, except you need to be careful to put filter into plastic bag or container immediately you pull it out. Be careful to insert seals properly when replacing filters.

Call me old fashioned, but I just like draining the oil out the bottom vs. the vacuum method.
I'm at 1300 miles on my 2014 250 BT and the oil looks seriously dirty. That dirt definitely has me ready to do an oil/filter change very soon and make sure that all the old oil comes out.

You are right. The oil gets black very quickly, but that is common to the industrial diesels that I've worked around in the past. Since the fuel has a higher oil content, the crankcase oil turns dark much quicker than a gasoline engine. I'm at 8700 miles and plan to change the oil/filter at 10K. My last two vehicles (gasoline engines) had change intervals at 7500 miles, so 10k is not that much farther. Please note that I'll accumulate 10K miles in less than 6 months, so there's no chance I'll hit the one year mark to require a change based on time.
I decided to let the factory oil run the recommended mileage, but I might change more frequently for the subsequent oil. Still undecided right now.
You really cannot do any damage to your engine to change more frequently, just your wallet. But the dark oil is not a reason for concern, especially for a diesel. FYI, I haven't added a drop of oil, yet.


First Benz diesel I had over 35 years ago I started changing the oil expecting it to clean up after the first time or two. Even flushed it after the first change when the oil turned black in less that a thousand miles. Thought something was seriously wrong. Must have run a case of oil through that thing and spent a lot of money and effort, until somebody clued me in. Now I don't even look at it. You'll never find a diesel with clean, clear oil! Do what makes you happy but don't expect 'clean' oil!
Cheers,
Mike
