Oil change fluid extractor

[jhendric]

Guys, I'm paralyzed by analysis. I have many tools and toys that require oil changes. I'm trying to sync all the annual oil changes to one oil change day. Most of the engines in question have their own starter battery. I'm thinking I should get a battery powered oil extraction pump as I can just pump oil from all of them into one large container. Still the appeal of not being dependent on a battery is nice. I also have access to air at home, for the most part all my oil changes can happen close enough to the air compressor line.

Please share your opinions on which has worked best for you, hand pump, 12v pump, air powered...

This is the one that I have, I have used it a few times and it works very well.
Hand pumping is no big whoop, it only takes a few pumps every so often to extract the oil.

I have been using one of these for years, only caveat is, it’s pneumatic. Gets plenty of uses other than oil.

Good luck in your quest.

I have had the mityvac air one for years and it works great. I recently needed one and mine was 400 miles away so I grabbed the harbor freight hand pump one and it worked good. I would have gone with the mityvac handpump just because I have a bunch of their stuff and it's been good but needed it that day so options were limited. I went with the handpump this time for the simple reason I already have an air operated one so now I have both options, and also saved a few bucks.

Mity Vac. Air powered (pneumatic). Several sizes available.

They even have one with a hand pump.

Mityvac hand pump is pretty good. I had trouble with the rubber doodad that connects the two diameter hoses, so I replaced it with a plumbing quick connect.

The pump started leaking oil after about a hundred oil changes. Parts are available on these.

Only use the correct replacement hoses. I used some hardware store something-or-other and it meted and got stuck in the dipstick tube. Fun day dropping the oil pan on that one.

Pela 6000. Hand pump. Around $75 on Amazon.

I have the mighty vac hand pump. It works pretty well but is slower than draining via the plug. I went with the MV because they have rebuild kits available.

Get a pneumatic with a large reservoir if you’re doing multiple vehicles.

I have a pump style, but the capacity is too low, so I don’t ever use it.

A larger one is less likely to tip over.

We use one at work and it is air or hand pump.
Works well for what it is. From Amazon, less than 100 bucks.

I have the hand pump version. I use it for all kinds of things, including recently emptying the last half inch or so out of a toilet tank to replace the valve kit.

Does an oil "extractor" remove the sludge and debris from the bottom of the crankcase like an actual oil drain?

From everything I've read this is debatable. I will say it has been the defacto standard for many boaters who keep their boat in the water or on a lift. I think a good solution will be to do the change via the drain plug every 3rd change.

If it's not moving with the oil when you **** it out, it's not moving when the oil pump does, so leaving it is fine. I'd rather use a drain, but there's a lot of stuff where sucking it out is the factory approved way to do it.

I have a hand pump one that looks very much like those in post #3. Have used it for many years, can't remember when, where or for how much it was bought, and what brand name. It is just a simple, reliable and very useful tool as is.

Was wondering the same. I'm religious about oil changes and all of our cars have some sort of magnetic drain plug. Even with oil changes before the recommended mileage, I'll wipe off some crud from the magnets. Someone posted after that maybe every third change should be a complete drain from the plug to flush out the **** lying on the bottom of the pan.

 

[Shiftless]

With normal engine operation, doesn’t all the oil eventually circulate through the filter? Why doesn’t the filter catch all of this “****”? For engines that have regular maintenance with oil and filter changes, how much “****” would I see if I pulled the pan from a well used engine?

Used my Extractor today...

Changing the oil on my diesel JD garden tractor is a real pain because to get to the drain bolt you need to remove the deck...
My HF pneumatic extractor is a joy to use... No pumping for me... I can hook it up and walk away... No spills unless I act like a fumbly old man...

When changing the diff fluid in my vehicles, I can stay under the car and work the siphon tube and not have to crawl out and re-pump the extractor... The air compressor just runs the pump without needing attention...

I've got an EWK Plus 6.5L manual pump one. It gets used quite a bit, though mostly by my sons for their bikes, boats & wave runners. I use it more sparingly. I don't use it for oil changes. I like getting under our cars & trucks to pull the drain plug and and greasing everything with a zerk and otherwise inspecting everything while I'm down there.

Was looking through my order history to see when I got it and didn't realize I'd had it even half that long.
Apparently it's been a good one. Not a lot of my plastic goods last that long.

 

[CMB41]

I use this one. Had it about 6 years with no issues.

About $250 and all metal so I went with it over the plastic variety. Does require a compressor though.
I still pull the drain plug. Only about a cup of oil remains so much less of a mess potential.

 

[Motown]

I have this one. Has a larger capacity than most.

I have the john dow pneumatic with hand pump, as well as a 5 gallon bucket with a 12v pump on it for boats.

I find the pneumatic one does a great job of getting all the oil out. I still get under the cars every couple changes to inspect and grease (truck).

I would definitely run the engine to get as much **** as you can into suspension before you **** it out. I also agree on doing a traditional oil change to clear the pan every so often.

A friend of mine was a boat mechanic decades ago. He told me they used to pull the oil sender and screw a hose into the port. Then they would start the engine and run it until the oil stopped coming out.

I’ve had luck using one of these to change the oil on my old Grady White IO. Use it as an oil pan, the put the lid on and pray for a few seconds as you bring it up from the bilge sideways.
