This Architectural Drawing is AutoCAD 2D drawing of Oil Drainage System. The process of forcing a nonwetting phase into a porous rock. Oil migrates into most reservoirs as the non-wetting phase, so initial charging of the reservoir is a drainage process. The drain plug is a large nut or plug located under the oil pan at the bottom of the engine. If you can't reach your oil drain plug easily, you'll have to either crawl under your car to reach it or jack up the car. All of the oil should drain out in about two minutes. It's a good idea to lay newspapers around the container to make sure excess oil doesn't spill in unwanted areas. For more details and information download the drawing file.
