Review on 🧲 Mityvac MV7300 Pneumatic Fluid Evacuator with Accessories for Direct Engine Oil or Transmission Fluid Drainage via Dipstick Tubes, 2.3 Gallon Capacity by Wayne Seba

UPDATE (17/08/2019): Old oil was pumped through the dipstick tube with no leaks. After the first 15 pulls on the crank, about half of the oil was drained, requiring additional bleeding to remove all of the oil from the sump. Assembled a jug of oil, new filter cartridge, wrench and 32mm socket to remove the old filter cartridge while draining the first half of the oil. Remove the old filter element while draining the other half of the oil. Move the tube up and down in the dipstick tube to make sure it reaches the bottom and removes all the oil. Because the end of the pipe has been cut at an angle, it is unlikely that it could fall and stop the flow of oil. Chaos. The used oil was then pumped into the now empty oil tank by pressing UP on the vacuum control valve on the side of the pumping mechanism. Most of the oil came out of the MityVac. There are no spatters here. Later I can use a paper towel, plug the ends of the tubes and hang the tubes to drain the oil left in the tubes. Oil. It worked like magic - once it became clear how everything fits together. I did NOT crawl under the car to see how much oil was left in the sump. The price of this MityVac pays for itself after I've used it twice as that's the cost of an oil change with full synthetic Mobil. to read. The diagram is not very helpful. The draw/dispense valve is not listed anywhere on the diagram, and somewhere it should tell the user to press the DOWN button to extract liquid and the UP button to dispense liquid. Also, the pressure/vacuum release button is not labeled on the diagram. I'll be using mine for the first time in a few minutes.
