ValvoMax Oil Drain Valve
 

A friend of mine recently invented this product. I think this valve replaces the oil drain plug on the pan. It allows for quick oil changes. What do you think?

Here's his website: https://valvomax.com

welcome to the forum. Many small airplanes have this already. it is good, quick, clean. until the valve sticks and leaks or debri gets in the valve area. But is good to install.
