Fumoto® USA | Quick and Easy Engine Oil Drain Valves
There is a video on the website. You remove the drain plug from the oil pan and install the valve in it's place. When you want to change the oil you can connect a length of hose to the valve and drain directly into your used oil container. No drip pan or tools needed. Nice and easy, I have installed them on all my vehicles for the past couple of years.
