Where does all the oil go?

Asked by majorrich (11926 points ) 2 months ago

Today I changed the oil in my car. I removed the filter, and let the car sit draining while I went inside for a meal. When I decanted the drained oil, it came out at about one gallon. I checked the oil level before draining and it indicated full. BUT! when I re-filled the engine with oil, it too nearly two gallons to fill it (after starting it once to fill the oil passages.) This is an older Mercedes 240D, and the oil never appeared clean when I checked the oil upon filling. It was black as can be. I am wondering if there is something I missed, or did wrong, or if Mercedes warps the laws of physics?
