ABSTRACT:
An oil filter cleaning system having a used oil and water receiving tank and a water supply tank. A used oil filter is secured to the top end of a pipe connected to a submersible water pump in the water supply tank and when operated will drive water under pressure up through the aperture in the bottom of the water filter and drive the used oil remaining therein out an aperture that has been formed in the side of the oil filter adjacent its bottom end. This flow of water and used oil that exits the oil filter is then directed into a filtration system located adjacent the top end of the used oil water receiving tank. The water filtration system has a large debris catching screen acting as a first phase and a fine mesh nylon filter acting as a second phase of filtration. The used oil passing through the fine mesh nylon filter floats on top of the water in the used oil and water receiving tank. The water at the bottom of the used oil and water receiving tank is free to pass to the water supply tank. This system allows for collection of the used oil by skimming off the top of the water surface in the used oil and water receiving tank.
