I know a few Mercedes guys changing their oil by sucking up the oil through the dipstick hole. I know we don't have dipsticks, so does that mean we can't use them on the N54?

This is what I'm talking about:

and why would you do that? There is no dipstick so the only way is to use the std. way .

[Mtech]

i say NO - sediments are at the bottom so drain the oil from the oil drain

[Sparky66]

Do we even have any openings other than the oil change plug, that are in the crankcase/Oil sump area??

[smack]

I would never use anything like that to suck oil out of the oil pan. Unless I didnt care about the car then I would use one. It will take longer to do it the std way but you can be sure all the oil will drain from the oil pan. Using the method you described will leave oil in the pan. I have used it before and then got underneath and pulled the plug and almost another 1/2 quart of oil came out.

that is how I change the oil in my boat, but I can't get to the oil pan because I have a water tight boat hull in the way. I can't see any reason why you would want to do it on a N54

This is pretty much what I use on my boat

But I wouldn't use it on my car as I see no way to get to the bottom of the sump

Ok folks,

There are benefits to the oil pumps. Because it allows you to suck things up instead of waiting for the oil to drain from gravity. Not only that but oil is designed to stick to metal so it will resist draining completely under gravity. Therefore your oil sump will always have oil film on it.

The oil extractors are excellent if you can get the tube all the way down to your oil sump. Then the benefits are obvious:

* You don't have to get under the car
* You don't need a new drain plug
* You get a LOT less mess
* You remove more oil than it would be to let it drain
* It is much faster
* You do not risk stripping the threads on your oil pan

The VW diesel guys are all about those oil extractors because they have filter housing just like ours and they can get the tube of the extractor right down to the oil pan. It really sucks if you have a closed cartridge type of oil filter and no filter housing. Then you have to use the dipstick hole to get to the oil pan.

I'd love to have one of these and probably will get one soon.

I'm sorry, but you have got to be the laziest person I have ever met. If you're that worried about it, just pay the money to have the stealer change it for you.

[vasillalov]

Its not about being lazy or not. Some people have to park their cars on a busy street and they can't afford the luxury to lift their car. Should those people have to worry about the quality of the oil change job they get from jiffy?

I am lucky enough to have two dedicated parking spots next to each other in my condo. I can have both doors wide open and the car jacked up and still not get into my neighbors space.

I also like working on my own car, and I do my own changes. I still believe that oil extractors are excellent if you know how to use them since they are able to pick up more oil. Plain and simple...

[Bobble]

Too funny. I have one and have changed the oil in my E46 probably 15 times that way car has 150K on it. Also that's the only way to change the oil in my jet skis and they have mega hours on them no problems. I've seen all kinds of go fast boats have service the same way on $300K boats!

[blisstik]

My buddy uses that on his E46 M3. He said it works really great, it just takes time to suck it all up but you don't need to jack up the car or use ramps.

For E90/E92s, Fumuto has a drain valve that you install one time and allows to drain oil without any tools. Just ramp up the car and move the valve. I got this info from Bill's Web Space.

[Rob@RBTurbo]

I have this same tool. Probably one of my favorite tools I have. Have only used it for siphoning fuel and change oil in the waverunners, never to change oil on a car though. If I was certain I could get it all the way to the sump however, I wouldnt hesitate at all... as they work excellent.

The fumoto valve is very very popular in the VW crowd and especially VR6 guys. There is a design flaw where the stream of the oil drain hits the VR6 mount support and splashes all over the place. Most VR6 guys use a 45 degree adapter in front of the fumoto valve.

[Tiago@VRSF]

My gripe with these is the fact that they don't pickup any contaminants in the oil which I tend to look at after oil changes.

I've seen flakes of metal in oil before which obviously give you an idea of the motor's health. Most people may not need to think about this stuff but these oil extractors usually limit what can be extracted from the oil pan/sump due to the size of the tubing.

[Rob@RBTurbo]

If you have debris in your oil bigger than the size of this tubing... you have much bigger things to worry about than a thorough oil change. The tube does a good job at pulling out anything you can get it close enough too.

As someone mentioned earlier, just try to use the fluid extractor tool first and once done pull the oil drain plug to see if anything was left. If nothing comes out, Id say it will work just fine. My guess is that it is going to be kinda hard to get the tube down to the bottom of the sump though which means you will not be able to get it all out.

[TensionPneumo]

Bump.

So, on an E92 there is a tube coming out of the oil filter housing that has a cap opening. Would I be able to feed a suction tube down there and extract all the oil? The only reason I haven't tried it is because there is a tamper-proof seal on it and I'm wondering if that would void the warranty if I break it.

Alternatively, would I be able to feed any tubing down below where the oil filter sits?
