DIY C250 cgi oil change
You will need:
-27mm socket
-13mm socket
-8mm socket
-ratchets
-small flat head screwdriver
-5.5l oil (I used Shell Helix Ultra 5w40)
-M271evo oilfilter (Bosch 1 457 429 261, Fram CH9918ECO, Purflux L366, Knecht OX183/1D, OEM A 271 180 009, A 271 180 01 09, A 271 184 01 25,...)
-something to catch your old oil in
-a piece of cloth or paper to clean up oil you might spill
1. Open your oil filler cap. Locate your oil filter. It sits behind the air filter near the firewall. It has an orange ring on it with "TURBO" written on it.

2. Take your 27mm socket with wrench and unscrew the oil filter. It's a pretty narrow spot so you might need an extension. Once you unscrewed it put a piece of cloth or paper in front of it so you can put the oil filter on it without making a mess on your engine.

3. Now you can use oil extractor or get under the car and remove the plastic covers under the car with your 8mm socket and wrench.

4. Locate the oil drain bolt. It's on the driver side of your oilpan. It might have some cables in front of it. Take your 13mm socket and wrench and unbolt it. Be sure to put your pan to catch the old oil in is in place. Drain all the old oil. And tighten the bolt. Place all the plastic covers back.

5. Fill your engine with 5.5 liter of oil. Might be easier to use a funnel. Once filled, put the cap back on.

6. Take your old oil filter and slide it off of the housing. Give it a strong pull. There are 3 rubber rings. If they are included with your filter, you might as well change them. Then slide the new filter back on to the housing.



7. Screw the new filter back in place and tighten it.
8. Use the service reset to complete the service.

If you are tuning your engine and getting more hp out of it, you can follow your tuners advice.
Thanks for the tip!
I am a proud new owner of a 2012 c-250. I want to make sure this is the proper instructions for my 1.8 L engine, first of all. Second, what I have read they are very specific to the oil used. Other then Mobil 1 euro, what options are there? Lastly, is it best to extract the oil or drain the oil, I hear draining leaves oil in the pan.
The only way draining will leave oil behind is if you have the car jacked up such that the oil pools away from the drain plug. I've been using the drain plug method for over 40 years with excellent results. Having said that however, I have become a convert to the extraction method since my Golf TDI has a belly pan with a bazillion bolts holding it up. I was skeptical at first but the extractor also works great. I will use it on my C250.
I think that the determining factor is not that one method is better than the other, but more about accessibility and convenience for the particular vehicle you're working on.
