Oil Evacuator

[carbob]

I've been hearing more about oil evacuators to perform an oil change, some of my friends use it and I know more of the dealers are using it including MB and Porsche. It's certainly easier but it is as good? Has anyone removed the oil with an evacuator then jacked the vehicle up and removed the drain plug to measure what's left and compare the stuff at the bottom with the stuff evacuated? If it's as good I may start doing this, it would encourage more frequent changes and be easier, and I'm looking at the pneumatic version- anyone have any experience with this one (uses your air compressor instead of a hand pump).

maybe it's just me but how would that be better than the old fashion way jack up one side of the car up take plug out go drinks some coffee come back every drop is out a sure thing
not to mention some drain plugs have magnetic on the tip to catch any metal shaving i would trust that over oil evacuators to give me a heads up . then again that's just me

I suspect the dealers are doing it to avoid the risk and hassle of removing and retorquing the drain plug. Let's them use even more poorly trained staff to perform that $200 dealer oil change. But think how stuck that drain plug will be after it has sat unmoved for 10 years...

The M62 oil pan and dipstick tube is conducive to this approach. You would be sucking oil from the lowest spot.

I've been using the Mity-Vac fluid evacuator (hand pump version) for about 10 years in all my vehicles. I love being able to do it. The only Bimmer I've had which had an oil filter under engine is the e53 N62. All other cars I never had to crawl underneath for any reason. And I love how much fluid it removes. And you can use it in the filter housing too on engines where the filter is a top engine mount. Sucks out the residual stuff a drain would not get.
I recommend this procedure to all my friends.

Ps: yes on my N62 I still use the fluid evacuator to remove all fluid so when I do drop the oil filter there is no mess.

A little bit of oil left in the pan is not an issue, some people (including me) only change the filter every second time (and yes, I use the service indicator for oil changes). I do find the evacuator kind of slow though and I guess it's harder to tell if there happens to be some coolant at the bottom. It is good to get underneath once in a while anyway.

I have an extractor that I used when I wasn't physically able to go under the car. It works pretty well. It does take quite a while compared to gravity, and you do have to pump quite a bit more than I expected.

The tank can be easier or harder to pour than certain kinds of pans depending on the pan you have. It's also takes up a bit of space and the hoses have to be kept upright or they will leak when not in use--they never really empty. No big deal really.

I have a magnetic drain plug, so I do drain most of the time to clean that off and see how many shavings it is accumulating as part of monitoring the engine health. You can't do that accurately using the vacuum.

I use one. But I went with something considerably more robust than the plastic extractors. Harbor Freight sells a steel tank version that is powered off of an air compressor. I think I paid about 100-120.00 with a coupon.

My compressor was 150.00 or so for a big one. I use it on all of cars including the n62 powered one. I just do not want to touch the drain bolt. On the m54 and m62 cars, it makes an oil change about as involved as washing the windshield. I pull out the same oil as draining ( you can see how much has come out).

Air tools make doing things easier as well, so if you think you might ever need an air compressor you might as well get the steel HF extractor. It is the same money as the Mity and will last much longer and won't ever blow up on you.

I don't use an extractor.

I have always drained the oil into a pan and let it settle and them pour it out slowly to see if there are any particles left and if there is anything on the drain plug. I think checking the oil by pouring it slowing out of a pan would be a good practice if you use an extractor along with checking the oil filter and bottom of the canister. Using an extractor is certainly a better alternative than have it done where there will be no checks at all. An oil change should be much more than out with the old and in with the new.

I don't use one either.

Gives me a reason to crawl under and have a good look around. Wife's N55/E70 doesn't even have a dipstick, so I have no choice on that one.
