I seen this unit on alot of websites how good are they at extracting oil and sludge i'm curious if they're as good or possibly better at removing engine oil than letting it gravity drain? anyone use these? i've heard they're great for vacuuming out atf before removing the pan and using to bleed brakes? I'm kinda skeptical cause it would be alot easier anyone use these?

Extract oil through the dipstick tube? Preposterous!

I use a Mity Vac Fluid Extractor and it works great. I'm actually waiting for the old oil in my CD to get sucked out through the dipstick tube as I type.

I use a Motive European Power Bleeder for brake bleeding. I wouldn't use a fluid extractor for anything but extracting fluid.

I use one – came from Harbor Freight, about half of what the tdiparts place charges for theirs. Works great for engine oil, gets as much out as gravity draining and eliminates having to crawl under the car. Oil suckers can also be used for removing transmission fluid from the pan but you still have to get under to drain the torque converter and change the filter so it doesn't save as much work as it does for engine oil.

I use a pressure bleeder for brakes, having never had much luck with vacuum bleeding. AFAIK, for ABS-equipped cars, a vacuum bleeder won't work.

I actually DO use the fluid extractor when flushing the brakes. I use it to suck out the reservoir before starting and to bring the fluid level down to max when done with the power bleeder.

I had a West Marine Hand pump vac unit, was not fast enough for me. I switched to a Jabsco 12v DC unit been using it for the last 2 years doing both the TDI (4 liters/quarts) and the MB's (8 liters/quarts) I think it needs a new impeller because it has slowed down quite a bit. I'm now waiting on the Harbor Freight unit to go on sale. If you get a suction type unit it can be used for other flammable fluids safely. Be sure the reservoir is large enough to collect all the oil in one shot.

The Pella unit is used by many TDI guy's.

Should also mention that MB dealers typically use an extractor though the dealership extractor attaches to the top of the dipstick tube rather than sending a hose down the dipstick tube. Has anyone tried a MityVac or Topsider using the dipstick tube?

If you have a second MB Diesel, use the brake booser line as a vacuum source

I know some cars are made to use the vacuum suckers to change the oil.
I know some on this forum have measured and compared one method to the other on their particular car and found no particular difference in amount taken out.

But in general I sure think that draining the oil out the drain plug when hot has some virtues. I think there is some flushing effect. And who does not love to have hot dirty oil dripping down your wrist once in a while ?
There may be a difference on your car between the lowest spot in the oil pan and where the dip stick points to... thus the efficiency of the draining may be more or less for some people. Perhaps taking it out the top every other time would be a good compromise.

I used mine twice today

Mityvac pneumatic model.

Topsider, works great. Gets as much oil as draining, and if you use good oil, no sludge.

I have looked at that but don't have the fitting that the dealers use and haven't been able to come up with an invention that would do the same thing. It would be marginally less messy, since your tubing wouldn't get oily on the outside. It might suck the oil out a little faster since you could use larger diameter tubing. However, that might not gain any time over all. I find that after I have "all" of the oil sucked out of a warm engine, if I leave it sit for a while I can get a little more out – a little more oil flows and drips down off of the parts and pieces inside the crankcase.

I have a small vacuum pump (surplus from the semiconductor industry) that I have been tempted to attach to my oil sucker. It would save some pumping.

I'm gathering u should go ahead and buy the air powered ones?

Johnhef · #13 11-23-2008, 05:28 PM

I did. I have a air compressor at home. BTW this is Mityvac sucker #5. they finally reinforced the housing enough to where the hot oil doesnt weaken it and allow it to implode. What a mess.

On Sale(?)

I use this Mityvac only on my TDI. Works great.

But on all my other cars. I prefer to drain the oil through the plug.
