The Pela unit pictured is a brilliant piece of kit-used one for years. This type of oil extractor can either be connected to the top of this built-in pipe or if the engine doesn't have a built-in pipe, the Pela unit comes with a selection of nylon pipes that can be slid down the dipstick tube right down to the bottom of the sump. Some marine units have a pre-installed pipe that is connected to where the sump plug would be on a car engine and it's other end is at the top of the engine with a cap on it. Marine inboard engines, petrol or diesel, cannot be drained via a drain plug, therefore most marine techs use this sort of oil extractor. Any heavy contaminants will stay in the bottom of the sump, the oil pump pick up point is usually quite close to the bottom so it is likely to pick up what you leave in there as well. It's a matter of how happy you are to leave this in there by using this method. The dipstick tube never reaches to the bottom of the sump so using this method always leaves some old oil in there. The filter is there to trap most of the contaminants found in the oil, if it gets blocked there is a bypass route for the oil which means all the contaminants stay in the oil causing damage to the engine. Part of any oil change should also include a filter change at the same time. The engine oil should be hot so that it runs quicker, undoing the plug and moving it away so tha the oil rushes out purging any heavy contaminants with it. If you jack up so that the plug is still at the lowest point then you will be ok. The theory is that the car should be on the level as the sump plug is designed to be at the lowest point on the engine. Oil Suction Pumps - any good? - coopshere
