Vacuum Oil Extractors

The MV 7201 works beautifully! I use it to change the oil on my dad's E350; that way I don't have to crawl under the car at all since the oil filter is accessible from up top.

I bought the Pela Pro 14

Works great! I had one similar to your link on amazon. Worked well but I just wanted more capacity.

I had that very model. Used it on a couple cars, maybe five times total Pump was shot. Metal can is nice, but the pump was garbage. Bought a green plastic one at Tractor supply company and have been using it for years. Dont like the tubing set up as much, but it works well.
 
So, except for having to get under a car, what is the advantage to pumping used oil vs draining it? And, how do you know you have pumped out all the old oil? Are oil stick tubes always in the lowest point of the oil pan? Just asking. This is a new concept to me. I find it curious that those of you who do it seem quite converted to the concept.

I have installed a Fumoto drain valve on my Outback. the valve accepts a hose barb, that has a 3/8" hose attached. With this I drain the motor oil right into the empty jug, for return to the auto parts store for recycle.

Even if I weren't using the Fumoto valve, it seems the number of steps are the same. Drain oil into a drain pan. Pour from drain pan to empty jug, to take to auto store. Or, pump oil into pump. Transfer oil from pump to empty jug, to take to auto store. Unless you take your pump directly to the auto store, and directly pour it into the recycle tank. Which, I would rather not do. Most of the recycle tanks I have seen are nasty dirty. I'd rather not be anywhere near them, unless I were in work clothes, which I typically am not, when I go to the store.

Am I missing something? Please share what is attractive about the pump method.
 
Oh, man. The hours I spent laying on the cold concrete under my cars. My back is permanently screwed from it.

Its so easy just to use the extractor, rather than put the car up on ramps (if you even can). I've done a hot change in under 8 mins, and didn't get dirty at all.
 
You also gain the benefit of not having to mess with the drain plug which means one less thing to worry about leaking. Once the drain plug is torqued with a crush washer it's not likely going anywhere. Ditto for no stripped threads although that's not a big problem for people who exercise care anyway.

The biggest advantage is not having to mess with ramps for low cars and laying on the concrete is not healthy.

Imagine if the ground was wet and muddy or snow covered but it was a clear day. You could change your oil without laying on the ground. This doesn't work out well if your filter is underneath though so it's application specific.

I use mine to service my transmission which doesn't have a drain plug, and I'd rather not pull a line going to the radiator. I extract the fluid, then drop the pan to service the filter. It's nice and neat that way. Once that's done I fill it up drive, and do a few fluid exchanges. Then I have nice fresh clean ATF in the transmission. It also works very well in the boat where draining the oil can be a real PITA.

The suction hose is at the lowest point of the oil pan in my MB E430. Before I extracted the oil I checked the oil level on the dipstick to see how much I could siphon, the marking on the Mityvac always matched the amount of oil in the engine. Someone posted in a MB board that he removed the drain bolt after extraction with Mityvac, no oil came out.

For other cars, LS400, S2000 and Volvo V70, it can extract about 85-95% most of the time.

It depends on the design of dipstick tube.

If you 3-4 vehicles and all have Fumoto valves installed, then the cost is about the same as Mityvac 7201. With Mityvac I can change ATF, bleeding brake ... One tool to do several things instead of just change oil.
 
Of course, as it is his chosen method to use.

I can tell you that as someone who runs a LOT of V8 powered trucks for business a drain plug properly located at the lowest point will be hard to beat as the flushing action of a fast, hot drain removes a lot of stuff off the bottom of the pan that no extractor will ever get from the top.

Pull a few dozen oil pans off older motors sometime. We stopped using Fumoto valves on our trucks because they slowed the flow too much.

May not matter to anyone but me. But I firmly believe it after seeing the sludgy build up with my own eyes, repeatedly.
 
I'm not sure which method is better. On Mercedes, I use extractor because the cars are pretty much setup for the method, so I figure it can't hurt. Plus, if you've always had the car, you probably know that lots of gunk isn't built up anyway.

I can also suck the oil out after a 2 hour drive after just 10 minutes of it draining back down with zero worry whatsoever of getting hot oil on me. It must be pretty good to bring oil out piping hot like that.

When it flows fast (from being hot), I'm sure you're still managing to suck up a good bit of any gunk that gets pulled towards the tube.
 
I think I'm going t try extraction with a 7201. I have a few small engines that could benefit from a vacuum extractor, regardless if I like it for auto applications.

If it does work well, that'll save a whole bunch of laying on the ground and messy oil buckets!
 
Ok: Highjacking.. Uses for extractor:

E.Oil
ATF (super handy for in-between filter intervals)
Power steering fluid
Suctioning AF during rad change / thermo change
Old gas removal from lawn equipment / boat tanks
(with right component composition)
Farm and lawn E.oil
Carrying to oil disposal
Whipping your bud with the tube, after he honks the horn while your under the hood.

Any other clever uses??

They don't advise using it for gasoline. What component composition are you referring to? Thanks.
 
mityvac 7201 for the dispense feature.

In the videos in this thread, I do not believe the guy is using the 7201, so he's not taking advantage of the dispense. You will want this!

He is also working in a shop, so for whatever product he is using, he can just dump the oil into the big used fluid drum/bin. For home users, you're going to need to transfer your used oil into a container to bring back for recycling, and that's a mess for all the other products without the dispense.

The possible negatives are in quality control. In the amazon reviews, there were a bunch of people who got 7201s which did not hold a seal. Test on water first, and return if it doesn't work.
