Bingo. I can get the bolt off rather quickly also, but a little valve to open is 100% mess free every time and there's no risk to over/under-torquing the pan bolt.
So far I have only used manual tools for oil change and that might still be the fastest way as one doesn't have to charge the compressor. Thanks for the warning!I find it impossible to happen to a Fumoto valve, unless that stone is so big accompanied by a thousand Newton force. If that ever happened, you will surely have a bigger problem aside from the oil.
I doubt that you have seen a Fumoto valve. I also have the same thought, I was thinking that it might be so easy to drain the oil that it might do an accidental discharge. When I bought one, I saw that you have to be intentional for the oil to drain.
The one from Scotty looks good, including the one you posted from eBay. However, I believe both will "impede" the flow of oil adding about three more minutes of your time draining the oil. It might be too much of a bother for you to have that extra time. And so we go back to the traditional drain plug which has and had been used.
Speaking of drain plugs, I hope you don't intend to use those pneumatic tools. If you meant it as a joke, I find it funny. That will be great as meme!
For the sake of those who are reading this and new to doing things on their own car, never use a power tool if you are just doing an oil change. For any other kind of work, it has it uses but not for an oil change.
I'd like to reiterate, again and again and again, never use a power assisted tool for an oil change. Just use an ordinary wrench.
I hope my English teacher won't see this, how redundant I am when a simple emphasis would have been sufficient.
