My dealer and I both agree, you get more oil out of your S62 pulling it out the dipstick tube with a pump than you do by draining it out the bottom. In fact, betweent the dealer's services and my own changes, the drain plug's never been out of my engine.
The "fill quantity" in the manual is 6.5 liters, or seven quarts, but it takes an extra half-litre to top mine up to the "full" mark on the dipstick when I change it myself with the lift pump.
I use an electric pump that I got from a boating supply place. It has a five gallon capacity - your engine has a lot of oil in it!

Depends on pan design. Some pans may be setup in a way that the gravity won't allow all the oil left in the pan to flow down to the drain opening. The oil extractor tube can be moved all around to suck that out. It's probably not going to be a huge amount on any given car.bmwusa said:Not that I disagree, but this seems counter intuitive, how could sucking the oil out be more effective then using gravity to allow the oil to drain out the bottom of the oil pan?? just wondering, Josh

THe tube goes down the dipstick tube, then you let it do it's thing, and when it seems to be done, you move the tube around to let it get some more.KevinM said:As I am about to buy lifts to attempt my first oil change soon, this is an interesting alternative.
Two questions:
1. Where does the pump hose go - I am inferring into the dipstick tube from one of the posts above.
2. What is the general range of costs for these pumps?
Thanks

From this I conclude the "drain plug" method leaves 1.5 qts of old oil. That is rather much.mottati said:After the oil extractor, i needed 8 quarts and i was still just a hair under the full mark, so it did seem to removea little more oil than usual.

13 bucks shipping to Cali.HDClown said:THe tube goes down the dipstick tube, then you let it do it's thing, and when it seems to be done, you move the tube around to let it get some more.
Mityvac makes 2 hand pump models for the job, they also make ones that hook to an air compressor.
The hand pump models are 7201 at around $60 and 7400 at around $45
This is one place with both: http://www.sjdiscounttools.com. Which is some of the cheapest prices I've seen on the 2 units. I'm not sure what their shipping is like however.

Since I have 4/50 extended maintenace, and will re-extend to 6/100, I'll be only doing inbetween oil changes. I'm going to assume the dealer does the drain plug method, but I can't say for sure without seeing them. So based on that, at ~6000 miles, I'll do extraction, and at my scheduled service, I'll get drain plug method. If I keep the car beyond the maintenance period, I'll probably keep the same routine, doing every other one with the extractor.DavidS said:From this I conclude the "drain plug" method leaves 1.5 qts of old oil.

What if any is the advantage of the drain-plug method? Faster?
(I used to think it was better to pull the drain-plug to flush out any heavy particles not cought by the retention-magnet in the oil pan.)
