DIY oil change, step by step, with pictures
Haha, sorry, I couldn't help it. I just ordered the maximum 12 quarts and it came to a grand total of $52.01. Fantastic, made my day, thanks Jeff!

Not sure, it doesn't give dimensions for the fittings. It's specific to the fluid evacuator they sell - but so is the other model, you just adapt your tubing to the suction side of the fitting. The key is getting the fitting with the side that fits inside the MB dip tube opening, the suction side can be put together as needed to whatever tubing your suction device uses.
There is a poster here - "kevink" I think - who figured all this out initially, the issue with the 4MATIC, diptube suction top adapter, etc. Maybe he will spot this thread and chime in.

He said he is not 100% sure of fitment. But he made it for Mercedes dealerships to use and only carries one model. He said it fits almost all mercedes disptick oil tubes. Never heard any complaints.
I think I'm just going to bite the bullet and try it out.
Good luck, let us know.

The oil filter is Mann Fleece HU718/5X. I have found this price to be pretty good, they also sell a lot fo 10 for pretty cheap too! http://www.fcpgroton.com/product-exe...008-2010+(Mann)
Don't use M1 5w-30, some dealers just use whatever. Only use 0w-40 or 5w-40 (if you can find it where you live) that doesn't have ESP additive for diesels. Conforms to 229.5 spec, not 229.51.
M1 5W40 meets 229.51 and is clearly labeled "for gasoline and diesel engines." That's the one the dealers are using.
Just today I used my Topsider to pull the oil out of a friend's CLK430. He works for a local dealer and bought the 5W40 from them so it's the latest.
Yesterday I bought three cases of 0W40 from NAPA which is on sale for $5.79 per quart until the end of December.

The good news is that I finally got my John Dow Industries Mercedes Adapter (Merry Christmas to me). The bad news is that it won't work for my w204 c300... HOWEVER, I did have somewhat of an idiot moment, I finally opened my Mityvac 7201 I bought of amazon and I found a rubber adapter pre-fitted on the tubing that will fit snugly inside my dipstick adapter.
Here are some pictures:
This is the adapter I ordered from the second NTX tools website (not the fluid evacuators adapter). The packaging says its from John Down Industries and took me about 2 weeks to get.

The wider part on the left is the exact same size as the dipstick adapter, so it will not go inside of the dipstuck tube, nor the outside to create suction. I suppose one could somehow tape the adapter to the dipstick and get it to work, but it is not plug and play. The smaller part fits inside the dipstick, but will not create suctions as it is too small, even with the rubber o-rings.
This second picture, however, is of the rubber end adapter that came with my mityvac tubing:

This has three steps that get gradually wider. The first notch is small enough to fit into the big side of my adapter (which is the same size as my dipstick tube). I haven't had time to test it out as it got dark and family is arriving, but theoretically this should fit into my dipstick and suck out all the oil, eliminating the need for me to use an adapter... You can see what I am talking about in this third picture:

I am kind of kicking myself for not just opening my Mityvac sooner as I wouldn't have bought and waited for this adapter to arrive that doesn't even work...
I will let you know what happens when I finish my oil change (hopefully by sunday). But just to clarify. This adapter DOES NOT work, unless you modify the setup.
My next change is in 2 weeks, I will measure the diameter of the fluid extractor adapter part to see how it compares.

You got yours in two weeks? Lucky you! I ordered mines on 12/13/2010 and have not received it yet! I will post results once mines arrives. So fluid evacuator are out of business?

I was the one that first found this place. When at the dealer for an oil change I watched the tech and asked questions. He showed me the adaptor, and I saw their brand name on the side of a drain tank. He said there was no MB part numbers .... the MB techs just order from FluidEvac's, the primary supplier to MB dealers in the US .
I've had good luck with the 7201 mityvac hand pump/evacuator, shown here:
http://www.mityvac.com/pages/products_fee.asp#07201
The small end of the Adaptor is about 10mm (.39") OD, and the largest tube that came with the 7201 is .41" . So just go to pep boys and get some low pressure SAE30R7 3/8" fuel hose. Use about 3" ... Nice snug fit. Low pressure drop allows highest flow (none of the Mityvac transitions are used) .

After changing to it, we saw a 2 mpg increase on the same summer trip from upper delaware to lower Virginia .... about 400 miles.
I used to run this oil in my 530i for a long time with good results. Here's a UOA in case anyone is interested.

Dealer did 1st change, and I think they used the current MB prefered 5W-40Formula M, pumped by hose from the drum to the "Adaptor" and into the dip-tube. I did the next change with 0-W40, as the Formula M is only availible in drums. The 5W-40 ESP Formula M diesel oil is available at dealers in quart containers. All other changes were with the Castrol.
The Benz is wifes car, and no amount of logic (from me) will convince her to warm up the engine before loading it, even when left out in 8 degree cloudy weather for 8 hrs. Thus my change to the 0W-30 GC.

It might not be a big deal, but I had read some posts where cars with M1 0W-40 had increased oil consumption at around 100K miles.

But, if you go to the latest MB owners manual downloads, it shows 1 Q less for the 4matics for only the 2010 and 2011. But for 2008 and 2009 downloads it still shows 8.5Q's for all models:
http://www.mbusa.com/mercedes/vehicles/class/class-C
So it also could reflect a design change in 2010. Several of us with early 4matics found that with the dealer type adaptor, ~8.5 Q's were sucked out and returned .... nyca was the most recent change.
I hope 08 and 09 4matic DIY owners carefully check oil level before change, and use either drain plug or an evacuator with the dip-tube adaptor for the job, and check amount drained and installed, and post the results here.

I then did my oil change and took out about 8.3 quarts (to my judgment). But this might make sense because I am pretty sure there might have been about .2 or so quarts left in the dipstick that I wasn't able to suck out. I think I should have reinstalled the oil filter before the mityvac started sucking air.
Anyway, I replaced with 7.5 qts and my new oil level is just about at the max point. Oops, I forgot to mention my car is a 2009 c300 4matic. Too bad my sister on her 2011 opted for the maintenance plan. I would have been able to see if hers has a smaller pan or something when she needs her oil done...
