Homemade oil extractor? for car/ boat?

[edwardh1]

Has anyone made one? maybe using a shop vac for the vacuum?
challenge is what to use for a collection jar?
anyone done it?

I used a home depot 5 gal bucket with lid, and a 5 hp shop vac. for some reason it didn't really work and I made sure everything was air tight.

I have a buddy at work that made one, but he's a rather handy fellow. He took a stout steel cylinder (not sure what it was)and fitted it with an appropriate valve. He pumps down the cylinder to a relatively hard vacuum, using a real vacuum pump, and closes the valve. Then he moves the tank into place, connects a tube and inserts it into whatever he wants to drain and opens the valve. He says it works like a charm. But we are talking a steel vacuum vessel and a hard vacuum here.

A good size fish tank pump with appropriate hose(s) ?

Just pay the money and get something that works!

I bought this one last week and I'm waiting one more week in order to use it for two oil changes on my car and van. I didn't just buy it for oil changes, but I figure it will pay for itself in 20 years! lol

Was looking at the 7.5L version the other day. How about an update? Does it work as intended?

Get yourself a cheap/free compressor off an old fridge or air conditioner. That's a cheap and really good vacuum pump. Now get an old propane tank. This is your vacuum/oil reservoir. The rest is just simple plumbing.
