There is no kill quite like overkill!
Yeah, no need to get one for most people.
I mostly ordered one because
- My car is low to the ground and it’ll be easiest just to flip a lever and be done
- I dislike crush washers
Aside from that I know some race teams will use them because that way they can do oil changes or fluid flushes while hot. I’ve only dumped hot oil on myself once and that felt amazing.
