This is what I have, Mityvac Fluid Evacuator Plus:
http://www.tooltopia.com/index.asp?PageAct...ROD&ProdID=8587

It works flawless on Mercedes Benz cars and trucks, because they are designed to use vacumm to suck out old oil from the dipstick tube.
I used it on my S twice, it worked okay the first time after several tries, but I could not get all the old oil out on second trial.

 

I'm not sure if this helps but if you buy an AEM style intake you'll find that with a drain pan short enough you can change your oil without jacking the car up. I love it!

 

I use the Mityvac on my M3. Works great, and makes oil changes so easy, my wife can do it in 30 mins or less w/out even getting her hands dirty. Then again, it seems like the German cars were designed with this in mind.

Now, for the S, I do it the old fashioned way. Just makes me feel better. But I think for people who live in the city, with no garage space, the Mityvac is a Godsend.

 

I'm surprised noone has mentioned the Fumoto Valve yet. I do it the old-fashioned way and jack up the car (even with my aftermarket intake), but numerous people swear by the Fumoto. Kick a drain pan under the car and flip the valve to "open" and drain to your hearts content.

Just another option.

I think in the 4+ years I've been involved with this site, I've heard of maybe 1 or 2 times when the valve has opened on its own.

I've heard of alot more loose drain plugs being improperly tightened by dealers and/or grease monkeys which lead to dumping oil.

I'd put it on if someone gave it to me. Like I said I get down and dirty the old-school way and don't want to spend the $40 on the Fumoto.

Fram also makes one...

It replaces the stock bolt, and then there is a second part that pushes the locking mechanism in and drains the oil. Also comes with a tube so that you can put the oil where you want it.

There is a cap for the bolt when you are done changing the oil so it will stay debris free.

I wouldnt trust that valve with the handle. I just do it the regular way anyways. Only way i would use one of those ways is if the drain plug threads got stripped.

 

whoa really? that's not good. i just bought one, and was planning on putting it on after the next oil change. the lock seems pretty good to me, i almost couldn't open it at first. the only thing that might've been a concern is the thing that blocks the opening -- it doesn't look like there's a lot blocking it. moving a mm out of spec looks like it could lead to a leak.

 

haha, yeah i got one because i messed up my drain bolt.
