I just wanted to see if any of you have done this job. So I want to remove the pan at the bottom to drain...correct? Do I need to replace the gasket...or is the same one reusable? Is it a rubber gasket, or something in a tube that forms a gasket? When I add the new oil...do I just add what is given in the owners manual? When I remove that plastic plug to add, do I need to loosen the bolt below also? Any help you could provide would be appreciated. Many Thanks!
