Engine oil fill ???
I am checking over and doing routine service before I put the car in use.
Car was dealer serviced by the book. I have always changed oil on all my cars and want to with this one as well. Sorry for being a long post.

When you use the common DIY method of inserting a nylon tube down the dip tube, it does not reach the bottom with the 4MATICS ... I tested this out and found the adaptor the dealer uses. (Glyn thought I was a nut at the time
)If you used the Mitvac 7400 or 7201 extractor, you can use the included rubber coupling bushing to axt as the $30 adaptor.
Try advanced search of W204 forum, using my "name" and oil and adaptor.

Since I am just "learning" the car, it was a used car I will have questions, I do search before posting. I am always thank full for answers from those who know these cars.
FYI, last time I extracted oil (using the MB adapter), I removed about 8.5 quarts, but I was only able to put in about 7 quarts of fresh oil before I hit MAX. So it would seem that (A) I did not extract it all, and (B) the dealer overfilled the engine during a previous oil change, which we all know they do all the time.

not sure what "no pressure loss" means ??
Your experience with your last oil change is exactly what I went through with the same 08 4MATIC. In your case answer (B) is correct ... dealer overfilled. Unfortunately, this implies you have not been checking your oil level, as it would have been overfilled??
Now the OP has an 09 4MATIC, which seems to take 8.5Q to fill, just like the RWD models. I wonder if there were a year or two, after 08, where the capacity was 8.5Q's, like OP. Later, the Owner's Manuals changed the capacity of the 4matics to 7.4Q's.
