What are they for??? Can't you just drain the oil? I think that would probably be tough in the tranny, but the engine and the diff are both pretty easy...

He probably doesn't want to drain the oil with slush dripping all over him.

I once used a suction drain. It was about 4 ft tall, and worked rather well, but it was slow.

Take a look at this one: http://blog.bavauto.com/8511/changing-the-oil-in-a-bmw-or-mini-vacuum-method-diy-video/

OK Ed... got me! I'd never seen one of these before!

Wouldn't you think that you'd get more crud out of the pan if you drain it from the plug? This IS definitely easy though!

We now return you to our regularly scheduled program...

That would be my take. However, it probably doesn't make much of a difference, unless it encourages one to change oil more often.

Actually, it makes me think that the combination of the two would be perfect... Get the car up on stands, ramps of jacks, drain the oil out with one of these extractors, and then pop the drain plug off, finish draining the crud without all of the splashing, and put it all back together. Certainly cleaner than the way I do it now. Wink

Gotta admit that the filter gizmo in that BMW in the video is far cleaner to do than my E30. Would be nice not to have to get under the car to struggle with that thing!

I'm tempted by the oil extractor if only to save loosening and re-tightening the drain plug bolt all the time. I had one that cross threaded and I had to have it re-threaded.

Now that I have a new oil pan thanks to the wreck, I may opt for the oil extractor method. But wanted other opinions from those that use that method. from all I've read, most everyone who uses it, prefers it.
