Oil Extractor

While researching maintenance issues on my neighbor's 2003 Mini I found that BMW uses oil extractors to change the engine oil. Forums show positive impressions. Apparently there are two commonly available; one from AutoSport and one from Mityvac. Has anyone out there used one of these and if so which model and why?

Thanks,
Gary

Laziness is not the issue

I will not buy a new tool unless I know it can be used on several vehicles. Since I will be changing the oil on that Mini as well as my MGB, neither of which I can comfortably crawl under, I was just wondering if anyone had used these before. Why not make life easier? The AutoSport 7ltr allows you to transport the oil to the recycler easily, no chance for spillage under the engine, no need to wait for the engine to cool down. Pros use vacuum extraction so why not me too?

Knightsog - did you try the oil extractor? Did you go with the AutoSport or Mityvac? I see lots of positive postings for these things in BMW forums. I'm wondering if they work just as well in a TJ.

I use the mityvac for my differentials since there is no drain plug and I have never been a fan of pulling the covers unless I need to. It works fine but takes awhile just to suck out a couple of qts.

I've always found that crawling under my rigs every 5K to change the oil is a grand excuse to inspect the rest of the undercarrage, lube the U joints and steering, look for leaks, broken or bad parts, etc......

I'm thinking of getting one so I won't have to drop the oil pan skid to change the oil. The oil pan skid connects to a small trans skid. Those two combine to not leave room to remove the oil pan drain plug.

Cool the oil down before oil change?

Hey, hot oil flushes crap much better out than cold!
They had these "oil extractors" at gas stations for self service a couple of years ago. It turned out useless because you have to change the oil filter anyway.
As already mentioned, don't forget to lube the U-joints at every oil change.
A skid designed without an opening for an oil change? Where did you bought that?

Just replaced all U-joints with sealed Spicer's. No greasing (but I do grease all the other greasable spots).

Teraflex. The oil pan skid has a hole for the drain plug. But, when you add their transmission skid plate it pushes right up against the drain plug. Stupid design, but it's in place on my TJ and does provide good protection. I'll try out this extractor idea so I can change oil without undoing the skids.

Skids (when new)




Skids not so new. Oil pan drain plug blocked by hinge for trans skid.

My Instructor in tech school was a master technician at BMW and it was common practice he said for the techs to use an extractor to change the oil. But you have to remember that you don't have to crawl under a BMW to change the oil as the filter is usually an inspectable cartridge type that is in front next to the valve cover usually and drops in and has a plastic cover. Just their way of staying clean and saving time.

I just received the Mityvac 7400 ($58- from Amazon). I'd give it a 4 out of 5. It worked as advertised. Sucked about 5 qts out of my TJ (4.0). Didn't spill a drop; and the old oil was in a canister that can be taken to your recycling place.

After you are done. You do need to store the 3 tubes (about 4' long) somewhere, and keep the residue oil from dripping. I wrapped the ends in a rag, wrapped with a rubber band, and shoved them inside a piece of 3" PVC tube I had laying around.

It does make an oil change easier, but not completely clean. I had several "spoons full" of oil drop out the filter when I removed it. So, you still need a catch pan, or a couple layers of newspaper at that point in the job.

Given I have an issue with my skid plate, I'm pleased with this tool for changing oil. If you don't mind climbing underneath and dealing with drain plug, and dealing with the oil in the catch pan - then I wouldn't bother with the extractor.
