Oil Drain Universal M18
New to me boat. Was pleased to see that the diesel had an oil drain hose. Got ready for first oil change; pan on cabin floor, oil absorbent sheet, new filter ready, ran engine to warm oil.
Then lowered the oil drain hose and unscrewed the plug
The question: Is there some sort of petcock on the oilpan that needs to be loosened to get the old oil to flow. Didn't feel like exploring under the hot engine, so closed it up and will use a dipstick pump today.
But would like to learn how to use the oil drain hose because it should do a better job of removing sludge from the pan
Thanks for the help
