Top Electric Oil Sucker
Brothers of The Benz
My "El Cheapo" Oil Sucker has a 2 1/2 gallon holding tank.
It doesn't experience the collapsing of the tank.
You don't have to pump for suction, just attach the clips to the battery and turn the pump ON.
It takes 1-2 minutes to suck out 6 quarts of HOT motor oil. I,ve never really timed it for while it sucks I am removing and replacing the oil filter.
It didn't cost $49.95. Not even $20.00.
It is OLD and still going strong.
