I don't like the idea of this valve. Why? For one, debris on the road ( ice, snow, road kill, etc ) can possibly open the valve. Sure it is a long shot but not a chance I am willing to take. Second, slow drain, besides taking more time, mean less contaminants coming from the engine and oil pan. A fast drain will remove more of these.
I use my garage and drive way all the time for all 4 of my cars. Buy some ramps. It only takes 30 seconds. There is easy access and the engine is tilted up and back so the oil drains faster.
As for burning your hand, I let the plug fall into the top of my oil container
( not pan), let it drain for 20-30 minutes. By then the oil is in the container and the plug is sitting next to the drain hole. EASY and no burns !
I say NO to the valve IMO..........
The position and location of the Fumoto is probably impossible for anything to hit it while you are moving. It would have to wrap around and behind the oil pan while in motion, I am going to say near impossible. If you have ever had one you know they are not easily opened. Many distributors also sell a clamp to ensure accidental opening is impossible. The drainage time is negligible and I doubt that more contaminants are left behind. A characteristic of oil is to suspend the impurities, I doubt there is a pile of crap sitting at the bottom of the pan that needs to be worked out. That is what an oil filter is for and if the car was just running, there wouldn't be any settling time anyway.
Maybe you are a traditionalist and that is fine, but no need to have irrational fears (not one reported Fumoto failure) and spread potential misinformation (oil contaminants). I have changed my oil with the regular screw, what magical technique do you use to prevent the oil from touching you?
