DIY oil change, step by step, with pictures
Absolutely don't leave the filter there.
Be sure to read the instructions that came with the filter about where the washer goes on the filter housing. Its possible to put it in the wrong place.
I've done 3 changes from the topside and have gotten almost all the oil out each time. I just don't see where buying low incline ramps, crawling under the car, removing covers, finding replacement plugs are worth the extra hassel and expense.

Sorry for not remembering the details any better.
It is very straight forward!
You need to remove the Black piece of plastic shield!
Then find the drain plug and unbolt it!
Since the bolt is sideway, the initial "burst" could blast up to 2 feet (unfortunately i wasn't prepared and caused some spill).
Then the rest is pretty much the same as other cars!
As for myself, I said what the heck, all the engineers in Stuttgart cannot be crazy... So I tried the top pump method and I removed all the oil in the system. Then, I removed the shield and verified that the location of the drain plug is on the side of the carter, so it is not more efficient to change oil draining from the bottom than it is draining by pumping from the top. In this crazy world, I feel more comfortable expressing my solidarity to the many times proven Stuttgart engineering.


It is about achievement, rather than the "type of work"!
It would be interesting if I were able to change the ATF.
I heard from other that the tranny drain pan only has one hole (for drain and fill), and it is temperature sensitive. ATF change would be extremely challenging without proper equipment.

Again, the fluidevacuators adaptor, used by the dealers, is needed for suction draining all 4MATIC models. Without it, you leave about an extra quart or more in the sump.
NYCA, you might be able to replace the 1/4" fitting on the pump with a 3/8" one. Looks like a simple tube grabber.
Contact Jabsco or a vendor for 3/8" suction line upgrade parts.

As for the ATF, there are plenty of posts regarding partial fluid change and total flush of 722.6 and 722.9 transmissions. As for proper equipment, the pump I use for oil changes plus a few small parts and hoses is all it's needed, though I procured a Laser Thermometer to make my job easier. The only other element is a little ingenuity to adapt procedures to your facilities, but a lift is a grand help.
My one and only satisfaction is the Swiss watch chronometer action my car maintains.

Reviews are gtear, just not sure how it will work with our cars.

No need to be scared of the unknown horizon.


Drain Plug -
If you choose to drain from bottom on MB cars do NOT reuse the drain plug and washer. Purchase new. The bolt is an "a" bolt it actually stretches a little when installed. Usually will develop small leak if reused. Better off replacing. only a few $
Filter -
The filter, The oem is designed to last at least 13k miles and is usually made of fleece. When using any other brands like K&N and so on
even though direct replacement they are not all designed to be replaced at those high miles. Make sure to verify you are purchasing one designed for that type of milage

Last weekend I decided to do first oil change on my 08 C300. For all the people interested in doing it yourself or just curious what it takes to do it I’m posting illustrated process.
My car is 6 months old and from the day one I knew that I’m not going to wait 10K miles to do first oil change and I knew that I’ll be doing it myself.
I was planning do oil change at 6-6.5K but Michigan cold weather kept me for doing it until last weekend.
On the first picture (“what’s needed”) you’ll see 9 quarts of Mobil 1- 0W40 motor oil, K&N HP7004 oil filter, small oil extractor and couple of other accessories.
Picture “7K oil change” is showing engine temperature around 55°C.
Picture “Engine cover” shows engine cover removal instruction.
After removing engine cover, remove oil dipstick and insert suction hose until hit the bottom of the oil pan. Other end of the hose insert in draining container.
Remove old oil filter, I was able to do it by hand and start oil extraction.
It took quite a while for electrical oil extractor to pull all of the oil out. I was even thinking what to do if that small pump gives up (it was really hot) right in the middle of process…
While extraction is in the progress, it’s time to change oil filter. Its very simple process: pull old filter straight out, remove two smaller O rings from the bottom of the assembly and one large around the cap and replace them with new ones (filter does come with new rings included in the box).Slide new filter back in to the cap and you are all set. Old (OEM) filter was MANN HU 718/5.
When the oil extraction is complete pull out hose, slide the dipstick back, put the new oil filter in place and start adding engine oil (8.5 quarts). When finished screw filler cap back and return engine cover.
Start the engine, let it run for a few minutes then turn it off and let it rest for 10-15 minutes, then check the engine oil level on the dipstick. Add some, if necessary.
Now couple of comments:
This is the first time that I was doing oil change by using oil extraction method. I decided to try small electrical suction pump (see pictures) that I found on e-bay (but you can buy the same one on Amazon), but I’m not impressed. It took long time and as I said, pump was getting really hot, to the point that I was afraid is it going to last long enough to finish the job. Maybe is nothing, but I just have no confidence in it. I will try to attach larger insertion hose, because original one has ID of about 3mm or 1/8” and see is that helps.
Like most of us, I was asking myself question: “How much oil I’ll be pulling out? Is it going to be some “leftovers”?” and just for the record: I did put all of the old oil in the empty bottles, that I had from the other oil changes, filling the bottles to 28oz…… and… (see the last picture) I end up having 9 (nine) 28oz. bottles and 1(one) 26oz. bottle… so all together 278oz of used motor oil, or 8 quarts and 22 oz. Slightly more then 8.5 recommended, but I was satisfied, because my dipstick was showing oil level on the upper limit.
Seams that dipstick tube is pointing to the lowest oil pan location, by design, but is going to take a few more oil changes before I start draining oil out in the big draining pan, without checking quantity (Am I weird or what?).
On the end everything went well, it took about 1.5 hours to finish everything including cleaning up and putting everything away. Actual work: about 15 minutes.
I’m open for comments and questions.
Regards
PS. I do have more photos. If somebody is interested I will upload them later.
