Oil extractor

[S54addict]

Watched a guy do a service on his zeeee 4M ( yes, he's American! ) but, he was using a topside oil extractor. I know they use a similar method in most garages, was just wondering if anyone had used and had any success to something similar at home?

A lot of people is using an extractor, but IMHO nothing compares with an old school draining...

Even the main dealers use these now but I still prefer to use the old fashioned draining method. You get all the rubbish out that way.

 

[S54addict]

Apparently, you extract more ok'd oil using this method and less chance of leaks. I also thought that it may leave any sediment in the sump?
This is why I'm asking the wise

Typo..... Old

Yep me too Mike, wouldn't want to leave any debris in the sump.

If a dealer employs people that they can't trust to do an oil change without creating leaks then God help us all. We have one of these at work and its main use is for general "sucking out" any leftovers in filter housing etc. after the filter has been removed on all of the Peugeot engines widely used across the car world these days. It was bought to do the early Smart cars which didn't have a drain plug. I cannot imagine how you can get more crap out of an engine using one of them rather than draining hot oil into a drain tray, or is that it? Hot oil.

Do you recommend engine flush Tony, I have never used but I'm considering for my next change on the Z

It is interesting that BMW main dealers use extractors to do oil changes but the latest models do not have dipsticks so I presume they will have to go back to doing it properly.

Confused... Obviously as you are in the trade you favour the more traditional method. Do you know if the BMW dealers use the top extraction method?

 

[t-tony]

I used it on my Z3 on every other oil change mate, I didn't on my Z4 at the last one but intend to on the next one. Roy always said how quiet the old girl was.

Tony.

ps. I use Forte products but there are others . . . . . .

MWPE. Looks like we were on the same wave length!

I don't know personally, but my manager at work used to work at Sopers so I'll ask him tomorrow.

Thanks for that pal, it will be nice to see clear oil on the stick

I did put a hydraulic valve lifter treatment (Wynns) in it at one change too, that was after using a flush and it was whisper quiet after that. Forte flush you can run in you engine for a day or so as it has very good lubricatin qualities most others do not and need the run and drain method. I put the flush in my Z3 one lunch time and drained it the next day.

Cool, obviously even though the dealer may recommend a product or procedure... They are not always right! But it's good to have an all round view suppose I was thinking of this extraction method for ease as I don't have a ramp but it looks as though I may need to lay off the mince pies and wiggle under there

I always jack the car enough to reach under and loosen the drain plug, then lower it and drain into a shallow try made from a cut down 5 gallon drum. Finally I jack one side slightly to make sure the drain plug is at the lowest point.

When I bought my Zed 8 years ago, it was an approved used BMW so to maintain the warranty, I had to have it main dealer serviced. At the oil change, I specified that I wanted the oil change done by the draining method. After I collected it, I jacked it up and the drain plug hadn't been touched. That was the last time they had my custom.

Main dealers will use this method as it's quicker and cheaper not because it's better for the engine.
On an S54 with such tight tolerances and it's appetite for rod bearings I'd stick with a proper oil change and frequent intervals.
