I'm sure this has come up in the past.I am leasing a 2018 Subaru with the 2.5L engine and I would like to add a Fumoto oil drain valve to make the job of changing my oil cleaner and maybe a little quicker.My concerns with the valve are leaking and construction.I know there must of been a few that got past quality control but for the most part most leave the factory the way they should.Do you get most if not all of the oil when draining?The Valve is made of brass.With hot/cold temperatures can the valve crack/split to allow leaks to happen?Alot of people like them.thanks Joe
