Just looking around in a catalog and ran across (again) one of those suction pumps advertising they make changing oil (or other fluids) easier? I just can't believe one can stick a hose into a blind hole and expect to extract all the fluids from the bottom of that pan. Then she's ready to add the required amount for an oil change etc. I always thought you wanted a hot engine so the oil or fluids will flow and any contaminants will be suspended and flow out with the old oil. Also the flow from a removed oil plug will take any heavier particles out of the system with it. I know my dad who ran a fleet of trucks used a dimiliar device to add fluids to the transmissions and rear ends of his trucks but the old plugs came out when it was time to drain anything. I have no experience with inboards so I might have to bite my tongue on this one but...... are these really used that much or just needed in special occasions.
