I bought the mightyVac unit:

I use it for doing differentials and transfer cases, but when I get a used
engine. It's nice to know I won't be getting it implanted on my forehead
pulling the plug before I install it.

MightyVac gives you a plastic tube that fits in the dipstick tube, and will
go to the bottom of the oil pan, in fact, if you go too far. It will not
vacum oil!

It works well, because I see it pull sludge from the pan bottom, that
pulling a plug doesn't get, and also, draining the broken engine, you
usually get a clogged line from metal pieces.

Pulling the plug puts that garbage in your drain barrel, so I put an
automatic transmission adapter on the funnel. That gets the large pieces out
when I pull the plug.

But, as a seasoned vetran, 35 years. I say that vacuming the oil isn't a bad
idea, because the pan isn't flat and pulling the plug leaves residual oil in
there too.

The dipstick tube doesn't go near the bottom of the pan, If anyone is
just sticking a hose on the dipstick tube itself, all they're going to
do is suck air.
