Thread: Oil Changing Question

Yes, they use an over the top of the tube method at the dealer, not a dipstick tube. I'll know for sure in about 3 months when I do my next change, whether the over the top method gets more out of the W204 4MATIC.

Yeah John - the diesel is a little more agricultural!

For my next change, I am going to try it with a tube that slides over the diptube, rather then down it, to see if I get more then 7Q out. The...

I used the Mityvac 7201 on my C300 recently & got basically the 8.8 litre container topped off so that when I inserted the plug - it pushed oil back out the tube. This confirmed to me that the this method works (again) to get all the oil out. There will always be a half qt caught up in the engine's valves & pistons somewhere no matter what - draining or suctioning.

I've searched the forums and cannot seem to figure something out. I want to do the oil change myself...thought is it possible to do without sucking the oil out from the top. Can't you just drain it from the bottom. Any insight would be helpful...Thank you so much! To remove this ad, register today or login if you already are registered! document.write(' ');

yes, you can do either, but ideally, extracting from top is better.
