I change mine every 5K miles in my SL600, and every time I get 8.5 qts out. The Mityvac has liter markers on the side of it, so you can see how much comes out. My car burns damn near zero oil in between changes.

The Mercedes dealership told me that most of the oil could be drained from one drain plug but that was BS. They also tried to discourage me from changing the oil because it would "mess up" the engine computer and it would cost $1200 just for the computer. I checked my invoice from last year's oil change at the dealership and it showed they replaced one copper ring so they only drained about half of the oil, yet they charged me for 9 quarts. Hope this helps!

Since it wasn't posted here, the best $$ value for Mobil 1 0W40 oil is at Walmart. Five quarts for about $25. Occasionally Mobil will have a promotion, and you can buy 5 quarts (maybe two 5 qt jugs, I've forgotten) for less than $20 each.
Having changed the oil in my SL55 3 times since purchase, I do not understand how the vacuum can drain the oil that is in the front of the two portions of the oil pan. I am fortunate to have a 2 post asymmetric lift, so my car is level when the oil is drained. Seems that if I drain the rear area via removing the rear drain plug first, at least a quart comes out the front plug when I remove it.
