What type of pump to pump used motor oil.
I don't need it to be under any pressure, and I don't really need any serious volume. I just need a pump that would be able to move thick liquid ( waste motor oil) through a 3/8" hose at a steady rate. I really only need it to make about a drip every 2-3 seconds.
I have played with gravity feeding, and it is just too unpredictable. I used a small fuel pump , but it was overworked, and did not live long. Any ideas??

Waste oil burner i'd guess.
Air pressure should do it.

I move large amounts of liquid (20-30 gallons of jet fuel) from time to time and use a Harbor Freight pump. Works fine but sounds like you need something that is running all the time for long periods of time...

Low flow and heavy viscosity get you into some form of positive displacement pump (gear pump, peristaltic, roller-cell, swash plate, piston, etc) or pressure dispense.

I built one of those mother earth furnaces about 7-8 years ago. It did throw some serious heat, but again gravity feed was a pain in the ass. It took 25 minutes to light it, then , it would barely run when it was cold, but once the thing started heating up , it would run like a mother and make my heat exchanger glow. It was fine as long as you were near it, and wanting to constantly tinker, and adjust the oil flow all day. I am wanting to just drip oil in my wood burner. It really throws some heat when I do this, and i am always sitting on a hundred gallons or so of drain oil, so it only makes sense. I am just looking to make the thing a little more automatic, If I run an electric pump, I can even add a thermal switch for an extra safety measure.
