Question, has anyone observed the pump apparatus that MB uses to change the oil in their cars and SUV's. I hear they no longer drain the oil from the bottom but pump it out from the dip stick.

If you have seen this pump apparatus do you remember if MB uses a pipe feed down through the dip stick hole or a plastic tube?

I'm getting setup to do my first oil change and just trying to figure out the best method to suck the oil out of the pan.

Thanks.

I think the method with pumping the old oil out via the dip stick pipe is the best. This is what they do at all MB garages.

This is what I use. It works VERY well.

No longer?

MB has designed for this since the '80s if not the '70s.

Dutch, is the tube diameter of the MITY VAC small enough to fit a 07 e550?I assume all 07s have the same diameter dipsticks but want to confirm before I order one thanks

The MityVac comes with two different tubes to insert in the dipstick tube.

While I can't answer specific to your model, I can tell you that the one I use fits nicely in my G500 (M113), ML320CDI (OM642) and my daughter's KIA Sportage. I would hazard a guess that one of them will fit your E550, too.

I have one as well, it's the only way to do it...just a suggestion, I wrapped electrical tape, on the suction tube, at the point in which the dipstick would be fully seated. I also cut a small notch to prevent the extraction tube from aspirating against the oil pan.

DUTCH

That's a good point. That MityVac will pull a mighty enough vacuum to collapse the main reservoir chamber when it has hot oil in it. Ask me how I know.

I also have had great success with the MityVac. Unfortunately, more new cars a dropping the dipstick for electronic oil readings (e.g. 2008 M3).

Saplegun, please explain what you mean by cutting a small notch to prevent the extraction tude from aspirating against the oil pan.Where is the notch?

GregW / Oregon

He means at the very end of the tube that gets inserted down into the pan through the dipstick. That prevents it from forming a vacuum against the pan surface if it was pressed against it at right angles. I have never experienced this, but its a good idea.
