I only ever use the Draper for changing engine oil, and when I am finished, I remove the top, and empty the drained oil into a plastic container. Then I leave it draining over night suspended over the container. By morning, all that is left is the color of the oil, and it's 99.9% empty. The main reason I do this is to monitor the amount of oil that has come out of the engine, this is important when it comes to refilling it. For the small electric pump that I also have, I run some petrol through it to clean it. As its designed to pump fuel, the petrol does not harm the plastics etc. So is safe to use.
