I suggest you let the oil drain for a full 15 minutes (or longer) to make sure as much of it evacuates the engine as possible. It will be a full thick stream at first, dwindling down to a trickle shortly. I don't replace the drain plug until it becomes an intermittent drip. After replacing and tightening the plug, reposition the drain container and remove the oil filter (again, this can be messy). Pre-fill the filter with new oil and coat the rim gasket with it (rub it on with your finger), then screw the filter on as far as you can by hand and give it another half turn with a filter wrench. The K&N filters have a built-in nub on them which makes removing and tightening them with a 1-inch wrench a snap.
