Had to do that anyway before transporting the used oil to AutoZone.

I'm doing the first oil change on my wife's 2009 c300 sport (not the first oil change, just the first one I'm doing myself), and I bought a mityvac to hopefully make the job a little less messy/easier. Do I need any adapters or anything special to put the tube down the dipstick? Seems like I saw another post where someone was using a dipstick adapter.
My other question is what else will I need other than the oil and filter? I just want to make sure I have all my bases covered since I still have a few days to gather parts/supplies.
Thanks!

You don't say which MityVac you have, (I have the 7201), and I used one of the rubber adapters that came with the unit
Other members purchased a metal adapter from some retaier ti believe its www.fluidevacuators.com.
And by theay, you don't have to stick the tube into the entire length of the dipstick tube. In fact, with the way I did it, the tube from the Vac went into the wide end of the rubber adapter, but it was not sticking out of the other side. So in reality, its actually sucking the oil to the top of the dipstick tube, through the adapter, then the tube, and into the MityVac.
I have found the MityVac to be a bit more time consuming than the traditional drain at the bottom process, and you'll have to pump it a few times to get all the oil out.... but all in all, it is cleaner, less hassle than lifting the car and slidng under, getting burned by that first gush of oil... Black fingernails...
You should browse through the entire thread. Yeah its long and sure the few a few posts you can skip over but in general, I found it useful.

IGB: It is the 7201. So basically I don't need the adapter from fluidevacuators...I can just push the rubber coupling that is supplied with the mityvac into the top of the dipstick tube, and it will form a good enough seal to suck the oil out the top of the dipstick. That's pretty dang cool if you ask me! I am stoked about using this mityvac! oil changes are not difficult, just always seem to be messy. No matter how hard I try, I always spill oil somewhere or get it on my clothes, or drip it on the motor somewhere. 
IYE Does the dipstick reach far enough into the oil pan to get all of the oil, or would it be a good idea to add the extra bit of small tubing to get everything?
will read through the rest of the thread now.

My only advice to get the oil out quicker for MityVac users are:
1) Make sure you open up the engine oil fill cap - air promotes better flow
2) Makes sure where the 'suck' tubes enter the MityVac bin - that there is a tight seal
** sometimes because of gravity, it bends the tubes a bit away from the inlet thus loosening the seal there & causing no suckage.

You don't want to add the engine side plastic tubing, and absolutely not if you have a 4MATIC, as you will leave a quart or two behind.

& am able to get ~8.5 qts out.
Should I not expect the same process with my new GLK350/4?

Ok, just got done with the oil change. Turned out to be more of a hassle than I thought. I really thought the mityvac was going to make it simple and clean. It could have...if I had of been better prepared.
Apparently the mercedes dealership way overfilled the oil. I mean, when I checked it I knew it read over the max, but I had no idea how much till today.
I used the method of pushing the rubber coupling into the dipstick and evac'ing the oil straight out the dipstick. It pulled out just a hair over 8L of oil before it started gurgling and sputtering. I pumped it up some more but it was basically sucking air.
After that happened curiosity got me and so I added the smaller piece of tubing to the coupling and pushed it down till I could feel/hear it hit the bottom of the oilpan. Then I pumped up the mityvac again and it started sucking oil again. Shortly after that oil filled up the whole mityvac so I had to stop and dispense some of the used oil into a gallon milk jug before I could continue.
All said and done I ended up with 6 full quarts of oil plus almost a full gallon jug. If my calculations are correct that's almost 10 quarts of oil?
8 of which I was able to pull out using the dealerships method of pulling from top of dipstick. The remaining oil came out via pusing the tube to bottom.
My best guess is that the dealership left roughly a half quart of oil in using their method of evacuating, and then added back in 8.5qts of new oil.

10 quarts of oil? Oh wow? Were you getting the "check oil level" message in the instrument cluster at any time?
On a related now, wife just came back from a Service B. Again, the oil looks to be over the "max" on the dipstick. They charged her for 9 quarts of M1, even though the car only takes 7.4 qt. I might have to suck some out if she starts getting the dread "check oil level" message again. Ugh...

No check oil or other lights that I saw while driving. Course it's my wife's car so no idea if it ever popped up while she was driving. She's very observant so I think she would have seen it and mentioned it.
milk jug is a little less full than i thought but it has got to have at least 3.5qts if the jug holds 4 total.

It's certainly plausible, but I think it would be a coincidence that it lost the seal (after holding a tight seal the for the 8L prior) right near the point most people would think to be all of the oil in the motor. It seems like I read where someone else found there to be at least 1/2L of oil in the motor after evac'ing via the top of dipstick.
It isn't a 4matic.

No - my C300 is not 4Matic. And the 2 connected MityVac supllied tubes suck out ~8.5 qts.
Kevink2, do you have a post you can reference for the 4Matic please. I am having a hard time visualizing this adapter method for the 4matics.

Well I oughta know something was going to go awry. 
Wife gets up to go to work and cranks the car and it's making a chirping sound. Sounds like it's coming from the front of the motor but I didn't let her keep it running for long enough to be sure. Freaked me out a little. Oil level is fine, but I don't want her driving it anywhere without knowing for sure where the sound is coming from.
The only thing I think it could be is that I sprayed some armorall on the plastic engine cover and maybe I got some on the belt? I hope that's it.

MB oil chg adaptor, a must for 4MATIC
Adaptor pic, 1st description of AGB Method with rubber bushing at top
oil-change, dealer-method
More Adaptor and Mytivac details
Adaptor still available, how to order
from a C300 parts catalog:
Dipstick:
----- W/4-matic
----- W/o 4-matic
It's also common knowledge now (thanks to others, not me) that the
4-MATICS take 7.5Q's, while the RWD's take 8.5Q's . Dealers still overfill 4MATICS !

When HOT, suck one to 1.5 out, & check dipstick, not dash.

Yeah, I already sucked some out, but it's still over max. I'll have to take out some more.
