Complementary Modification:

Flush your cooling system and replace your radiator hoses

One of the most common tasks to perform is replacing your engine oil. Frequent oil changes are perhaps the most important procedure you can do to maintain and prolong the life of your engine. With the better oils that are available today, the requirement for frequent changes is diminishing. Even though Mercedes Benz recommends oil change intervals that are much further apart than in the past, I usually recommend that you keep the changes under the 5,000-mile limit. If you don't drive your car too often, you should change the oil at least once a year to keep things fresh.

The first thing you need to do is to make sure that you have everything that is required for the job. Nothing is more frustrating than emptying your oil, only to find out that you don't have a replacement filter or enough oil. You will need an oil filter kit, a 13mm wrench, an oil filter housing socket, a new drain plug gasket, a roll of paper towels, a very large oil pan or bucket, and 9 liters of oil. Start by driving the car around, and let it heat up to operating temperature. You'll want to empty your oil when it's hot, because the heat makes the oil flow a lot easier, and more particles of metal and dirt will come out when the oil is emptied.

Next safely jack up and support your car. With the car safely off the ground you will need to remove the engine tray. There are six 8mm bolts holding the tray on, the rear two also help hold the transmission tray. If you are going to leave the transmission tray on, remove the rear two bolts first, lower the engine tray, reattach the transmission tray bolts, then remove the remaining four bolts on the engine tray.

On the rear of the oil pan you will find the 13mm drain plug use a wrench and remove it. Remember the oil is going to be hot coming out of the motor so make sure you don't burn yourself and try not to drop the drain plug in the container you are using to catch the oil. Always dispose used motor oil according to the regulations where you live. Most oil change shops or your neighborhood parts store will take your old oil and filter to be recycled properly. Once the oil has emptied reinstall the drain plug with a new crush washer. I always like to make sure I reinstall the drain plug before I start working on the top of the engine, just so I don't forget it later. Reinstall the engine tray.

Move to the engine compartment where you will find the oil filter housing as well as the oil filler cap.

You can easily perform this job without removing the engine front cover of air ducts but I removed them so you can have a better view of things. If your engine cover is new, shinny and clean you may want to take a moment and remove it (please see our article on replacing your air filter).

Now you can see the oil filter housing and the oil filler cap. If you are worried about how tight to tighten the filter housing you can use a little white out or other marking source to mark the housing and filter, then just tighten it up until they line up again.

Place your oil filter socket over the filter and remove it.

With the filter loose you can pull it straight up and out of the housing. Be careful as it will be covered in oil and has a tendency to drip.

Slide the old filter off and inspect it for any metal. There are four separate rubber o-rings or gaskets on the filter holder, thankfully they are all different sizes and will only fit in one spot. Use a little of your new clean oil to help get the new o-rings in place.

Here is a trick when it comes to filling pouring your new oil into the engine. The Mercedes oil filler opening is not that large so it is easier to just use the filter housing as the place to pour your oil in, it is large enough to hold the whole quart container hands free. Put 8 1/2 quarts in and reinstall the oil filter housing.

Begin by safely jacking up and support your car.

Mercedes c240 2002 Comments: Thanks Nick for your answer, i got the torque from my friend's owners manual for some reason it was 70 NM but i realized today that the right torque is 25 NM ... i bought a small pliers and was able to get the stuck piece out successfully , then install the new filter housing i bought from amazon .. everything went good .
July 8, 2016
  Followup from the Pelican Staff: Phew. Glad it worked out. - Nick at Pelican Parts  
Mercedes c240 2002 Comments: Great article, I have a problem and will appreciate any help .. was trying to do my oil change as usual, but last time i followed the torque for the oil filter cap and unfortunately i did 70 NM as stated but that was too high torque .. when i tried to loosen the cap the filter housing it self broke in 2 half ... so now i have the half of the plastic housing stuck in the oil filter tube .. and at the same time i'm not sure if there any broken plastic pieces are in my system now ... i caught a small plastic piece and took it out but i'm not sure how i will get the stuck plastic and how to check if there is any materials swimming in my oil now .
July 6, 2016
  Followup from the Pelican Staff: Where did you get that torque spec? The article doesn't mention torque. You may have to remove the housing, then break the plastic pieces out, then reassemble. - Nick at Pelican Parts

Chrissy83 Comments: My 2000 ML320 I just bought does not have a oil dipstick. I was stopped and the oil light came on and shut off. My friend says the dipstick is there just the ring is broken off. When I bought it from the I'm guessing a half ass deal told me they don't come with a dipstick now I am so confused. I watched a video and it says 8 quarts to change and fill it up is that true? Oh yeah and the air bag light come on n off do u know what the problem could be? When we play with the seat belts it goes off but then on again. Could it be a short somewhere?
May 29, 2015
  Followup from the Pelican Staff: If you have an airbag light on, you will have to scan the vehicle to read the fault code. Can't guess at that sort of thing.

Can you share a photo of the part you think may be your dipstick? You should have one.- Nick at Pelican Parts
 
Steve Comments: I also wondered why the third rubber gasket from the bottom has 2 in every kit - do you double up on it? Also, the filter is not a OEM Mann - the Mann filter has glued horizontal support strings covering the filter media that keep the pleats uniform under pressure. The filter in the illustration has no pleat support and subsequently the filter media has bunched up due to distortion. It obviously was a cheap filter.
May 26, 2015
  Followup from the Pelican Staff: The additional gasket is likely for different engines that require it, so they send it in the kit. - Nick at Pelican Parts  
X Comments: After draining the old oil, is there anyhting that could be poured into the engine to help clean out any fragments left, before pouring the new oil?
I own a 2005 E320
April 26, 2015
  Followup from the Pelican Staff: No. You can remove the oil pan. - Nick at Pelican Parts  
tim Comments: The pictures show the wrong oil is 5W-30, should be 0W-40 Mobil 1 and the wrong filter. OEM filter has no metal on it, plus the filter doesn't look like it worked too well.

What is the beat oil to use for a 1998 merc. ml320?

Cmm112 Comments: Could by not installing one of the four gaskets you leak all the oil from a fresh oil change and filter change? Would the leak cause spray pretty much over the entire front of engine bay as well?
Apologies for not really having the applicable models stated either...
August 24, 2014
  Followup from the Pelican Staff: If you leave the large cap O-ring off, the oil will leak out of the oil filter housing. - Nick at Pelican Parts  
Marsh Comments: After a Mercedes Certified mechanic replaced the rear seal on my transmission, my driver's side seat belt suddenly no longer worked; it pulled all the way out and will no longer retract. I giggled it and heard what sounded like to me to be the retractor completely loose. My question is this:
1a are the bolts holding the seat belt retractor inside either the engine tray or the transmission tray?
1b is it possible that the mechanic unbolted the driver's side seat belt retractor in order to remove the transmission?...and then forgot to hook it back up?

I am searching for how this could happen since my seat belt worked perfectly prior to this mechanic's work on my transmission and A/C unit, but he is saying it is not his fault and does not want to fix the seat belt; saying it is a separate problem not included in the price I paid to fix the rear seal & A/C.
August 8, 2014
  Followup from the Pelican Staff: I can't see how the two are related. I think it is a coincidence. - Nick at Pelican Parts

James Comments: 1999 ML320 - I just inherited this vehicle, and it sounds like a diesel with all the noise coming from the valves maybe - too noisy for it to be lifters.
Anyway, I changed the oil today and attempted to put a quart of Lucas Oil Stabilizer down the oil filter housing and it would not drain down. I let it sit for about an hour and there was still fluid standing in the housing about 2" up. I then put 7 qts of oil in the oil filler opening and put the filter back in the standing oil in the housing.
Also, when I removed the old filter there was no oil, to speak of, dripping from it - but the dip stick read full, and I had just driven around to warm up the oil as you suggested. Also, there was no long spike at the bottom of the oil filter like your picture shows.
This doesn't sound good, but I was hoping it might be an easy diagnosis.
Thank you, James
August 21, 2013
  Followup from the Pelican Staff: After you started the engine and shut if off do you get only in the filter housing then? You probably have a lot of sludge built up in the valve cover baffling that is blocking the oil stabilizer from draining into the motor. You may need to pull off a valve cover to look at how much sludge has developed. - Kerry at Pelican Parts
