You presented an excellent oil change process outline, Jolly. But just to be sure, I would emphasize that the oil system should be open at only one place at a time. The tank should be connected and contain oil while changing the filter. The filter should be in place while draining and refilling the tank. Otherwise air will enter the oil circuit, which then requires the pressure purging process.
