Agreed - but it does vary depending on vehicle.

I think with the X3 if you move the feed tube around when it seems to be finished you can get just about all of it.

Or at least as much as you would get with a conventional drain - but that also varies between engine pan designs.
The M54 engine has the drain plug coming off horizontally, whereas the N52 is more vertical.

The quick lube outfits use an extractor as do a lot of dealerships.

Except for those with finned pans, like Subura.
