Thanks for the replies.

I've got one the tall mityvac canister sized units and the smaller syringe style. Both get used quite a bit and have held up well.
I wish the canister had included longer tubes, but it's great otherwise.
I have the tall floor mighty-vac that holds like 15 quarts, works great for all kinds of things...used it yesterday to suck 4qts of 75w-140 gear oil out of a dana 80 rear
Well the ambient temp was 113 outside, around 105 in the shop....but the truck hadn't been driven. Sucked it all out in about 5 minutes, I was impressed
Sometimes. It's great for things like transmission fluid where you don't have a drain plug and have to just drop the pan and hope for the best. On a taller vehicle, the tubes that come with the unit aren't quite long enough, but that can be fixed with a trip to the hardware store.
Refrigerator icemaker/water hose works.Kinda like pex but not.
Never stick hose in something too hot.It could collapse and get stuck in dip stick tubs.
Changing a dip stick tube is a pain but not all that hard. Either engine or trans. Of course the last time I did it was on something built in the 80's.
I recently just used an vacuum pump and a 5 gallon gas can to suck the transmission fluid out of my van, it was crude but it worked. I am interested in other options that are out there for future projects.
Best other option is pneumatic.Lots of ways for a home made unit.
I had trouble bleeding trailer brakes once (had a bad leak I didn't know about), so I hooked a clear tube to a vacuum port on my car engine. I put a MityVac cup inline to reduce the chance of sucking brake fluid into the engine. Worked like a champ.
That's some mad MacGuyver shit right there. Brilliant!
West Marine sells a good one and it is actually a rebadged Pela 650...have used my for years at home and on the job.
I use a MityVac 7201 tall unit for draining gas out of tanks, brake bleeding, transmission draining. $110 or so on Amazon. You will wonder how you ever got along without it.
I purchased a Mityvac 7201 8-9 years ago when I briefly owned a Mercedes-Benz. Used it twice to change the oil. Haven't used it since and it sits in its original box next to my toolbox.
I have the larger mity vac non-pneumatic. It works but I would get the pneumatic one, works better in every way.
This is what I use. https://smile.amazon.com/gp/product/B0042KJ53W/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
it works great especially for European cars with the filter cartridge up top. No need to get under the car. I have used it regularly for over 5 years.
I have never used one of these, but it seems every car i own has the drain plug right over a crossmember, diff, steering rack, etc, so oil coats it, runs along it, and despite best efforts i still find oil drips days later. These go in through a dipstick hole? How long does this take? Are you guys reasonably confident they remove all the old oil?
Good comparison video:
Then an update comparing the Topsider. And this one addresses your question about whether is gets as much oil as draining.
The Reader's Digest version: for $50, get the Topsider.
Very compelling. Saves you from jacking up the auto, jacks stands, MESS, etc. I think I'll get one, the new Ford drain plug, which I probably have, sounds like a pain anyway.
edit: Hmmm, what do you think of this video. He had different results but was going to use the Topsider anyway.
Yep, down the dipstick tube, and the West Marine/Pela 650 unit I posted comes with two tubes to fit various sized dipsticks tubes. Oil extractors won't work with all engines as in some cases you can't get the extraction tube to the bottom of the oil pan...but works on most in my experience with cars and lotsa generators (plus dry sump bikes). Goes much quicker if the oil is hot, maybe 5 minutes or so for a typical auto engine that holds about a gallon of oil.
