Oh man, this brings back old memories. I had one of those drain valves some 20+ years ago on my 81 Civic.
Nice gizmo, if you do your own oil changes and want to cut the process down to under 5 minutes. (Great for the track btw)
However, I'm not sure if it would stay on there if you take your car to the dealer or other shops for maintenance. They might not know about it or even like it so much that they'd decide to keep it as a souvenir...
One thing to watch out for is the design of the drain hole/plug that it doesn't stick further down below the bottom edge of the oil pan, 'cause it would suck if it protrudes too low and one day it gets snapped off while driving... :eyebulge:
