which model oil extractor you all use?
6.25 Gallon Harbor Freight
6.25 gallons holds several oil changes. I have two now, one is for oil changes and another for "clean fluids" around car and house. I even used the clean oil extractor with a small suction cup mounted to the end of one of its long extractor tubes to retrieve a DVD case that fell into the "bad place" in my Super Console.
