So, just got my wife a 2012 C250 sport, and began thinking about oil changes. I read all I could on the forum here and got a Big Boy fluid evacuator. I called Fluid Evacuators to order the Mercedes Adapter and the guy told me they don't work unless you have one of their evacuators. He said he got a lot of orders from people on "some forum" and had to make a lot of returns. He was not even going to sell me one until I told him he could note "no return" on my order. Looking at the adapter, looks like you could apply a hose over the o ring and clamp tight enough to get an airtight seal. I have not seen instances where members here advised these adapters did not work unless you have a proprietary system. Did I just miss this. Also, I have read and read my manual and read here, and it seems like here in Houston Texas I can use 5-30W, synthetic. I know everyone has beat the oil change subject to death, so hope this did not bore everyone to death, but I actually did read the manual and the forum.

I found the adaptor, used by dealers with a special hose & fitting, but easily used with 3/8" hose over the short end with o-rings in place. Any approved oil is ok, but M1 0W40 is better for hot summers like texas.

I just bought the adapter about 3 weeks ago ... a 3/8 hose will fit fine over it ... and all it is is a quick disconnect coupler like on air hoses to begin with ... their evacs are nice too ... slightly pricey ... and the drain is a low pressure drain ... i've seen others that still need the air source attached just to drain .... just get there 3.5 gallon evac .. and if you have other cars they have a hose set too for using to chaining oil, and tranny and brake fluids as well ...

I have the adapter, but I am having trouble inserting it into the oil dip stick tube. The smaller diameter short end appears to be too large of a diameter to fit into the dipstick tube. I am afraid to force it too hard. Has anyone had this issue. I purchased the MB adapter from fluid evacuators, but am confused as to why it does not fit. Should I push it harder? Any help with this issue for my 2012 C250 will be appreciated.

The adapter works. When I ordered it, I told these guys that there was a good market for a smaller/less costly powered fluid extractor for the DIY mechanic. I didn't have much luck with the hand pump extractors, I ended up with a 12V powered unit from a marine store, it makes the job alot easier. Their extractors are good looking units, I see they make a smaller 3.5G one now but it still requires shop air.

Thanks so much for the reply. Regarding your statement that the adapter "works" can you elaborate. Specifically, I am having a difficult time pushing the adapter into the dipstick tube. I am thinking that the o ring might be causing the fit to be tight, which it needs for an air tight seal. However, I am not sure just how much force to apply. Should I lubricate the o ring? I'm just afraid to bend the dip stick tube pushing too hard since this is my first experience with a Mercedes. If you could expound on how easy the adapter was to insert, or how much force to apply I would very much appreciate your experience. If you have a 2012 C250 it must be the same procedure. I ordered the adapter from fluid evacuators for the Mercedes oil change. Once we establish these parameters are the same, it must be that I not applying enough force.

Not sure if the dipstick tube on the C250 is any different from our C300, but the Fluid Evacuators adapter works just fine on ours. It requires some force to push it into the tube, but not a ton of force. Definitely lube the o-rings to help it slide in easier. It's actually harder to get the adapter off the the tube after extracting the oil.

Also, can you post a picture of the adapter that you received? Does it look the same as pictures posted on this forum earlier?

In addition, you don't really need this adapter. If you buy a MityVac extractor, it already comes with a rubber adapter that should work just fine in this application.

As for the oil, you can use 5w-30 if you want, but not just any 5w-30. It still needs to meet MB 229.5 spec. If it does, you're good to go. Most synthetic 5w-30 oils found at local auto part stores do not.

I bought this Mercedes adapter:



I already bought the Big Boy Topsider, so Ill give that a try

OK, so of course you are plugging in the fat part of it, the one with the two orings, into the diptube. Lube it with a little motor oil. But if it doesn't fit easily (it doesn't necessarily have to bottom out), the diptube on the 250 is different than the 300/350.

gregorywilliams

Alright, now it becomes clear, and plan B is in play, except that I don't have a plan B. Thanks so much for the responses. It is now apparent that the dipstick tube for the C300 and the C250 are vastly different. I ordered the adapter without knowing the size or dimensions of the adapter and unfortunately, believed it would fit. Guess we have not had a lot of people with C250 oil changes yet. The small end with the one O ring won't even fit in the dipstick tube much less the large size with the two o rings. Oh well, $24.95 for the part and $10.95 shipping could have been worse. Anyone have thoughts for Plan B. Any other adapters that will work, anyone with a 2012 C250, sport model, 1.8 liter?

Mercedes has used that evacuation system for decades, and why would they put on a different dipstick tube on just one model? Call or stop by the dealer. Either get a tech on the phone or better have him verify the change.

I bought one of the West Marine evacuators, which has a tube that slides down the dipstick tube and into the oil pan. Perhaps trying this type of evacuator would be easier?

I just buy this cheap one from ebay

It works fine for me, I didn't need any adapter or anything, i just push the tube all the way down the dipstick and hand pump the oil out. You can find something simliar to that at walmart, but the brand is Prestone. It goes about $8.

nyca

If the opening on the dip tube is that much smaller, then the dipstick itself must be different because the top makes a seal atop the diptube, so it would have to be the same dimension to fit. Maybe post a photo of what the top of the C250 diptube and dipstick looks like.

Since Gregory is afraid of calling a dealer, I called the GF's dealer. Service and Parts guys both said nothing is different to their knowledge.

I supect Gregory may be opening the cap off the transmission fill, on the back side. So stop looking for that back door entry, and look for an OIL dipstick.

Good Idea, how long does it take to empty the crankcase?

I have a very similar one, but it just has one set of preinstalled 1/2" od tubes, which I figure will not fit dwn the tube.

Greg is most assuredly not afraid to call the dealer but finding the dipstick was never my problem. My intent was to find the best method to remove the oil. If you look at page 279 of the C class sedan manual you will see that the oil dipstick is clearly identified, thus I can make a clear distinction between the dipstick tube and any other component. I don't know what the prior C class dipstick looked like or its diameter but they are clearly different. This would not be the first time an "expert" from a dealership was not updated on all components. I am not trying to bore you guys, but I was just trying to find the most efficient method. I am surprised that another member with a 2012 C250 has not encountered this issue and posted here. As I indicated in an initial post, the fluid evacuator employee advised that the adapter would not work, but based on the general consensus on the forum here I decided to purchase the item. This is not to pass judgement on any forum comments, just to note that the fluid evacuator employee was obviously correct. Thanks for those who posted comments. It is always beneficial for a new member to receive assistance without ridicule.

Take a photo of the 250 diptube top with your adapter sitting atop it. Something is not right here. In the early days of this W204 board, the folks with 4MATICS could not empty all the oil with tube inserted into the pan (by design) - finding a vendor for this adapter solved that problem for all of us.

Recently changed the oil on my 2013 SL550. Utilized with a Mityvac 7400 to remove the oil. Inserted their included hose into the dipstick tube until it stopped. Got all of the oil out with no problem. I encourage you to give it a shot. If it doesn't work just put the oil back in and drive to the dealer to have them do it.

I second the adapter sold by Fluid Evacuators. Even lent it to a neighbor for his GL diesel. Worked well.

Where did you buy your adapter from? Fluid Evacuators won't ship to Canada.

Bought an adapter from Fluid Evacuators and used it this weekend on my W212 connected to a MityVac, worked great. I needed to apply some Vasoline to the adapter, put a deep socket over it and tap it down gently with a rubber mallet to get it secured to the dipstick tube, extracted +7L. Where have you been all my life?

onceover

I'm struggling to find information on the adapter. Can anyone point me in the right direction?
