Good Evening Mr Kilmer
Recently I watched as the dealer sucked the oil out of my 2021 Kia Sorento through the dip stick hole with a suction hose. The Kia service manual says to drain the oil using the drain plug. I understand the oil suction machine they use is not exclusive to Kia but is also used by Toyota, Honda and a lot of the quick oil change places. While convenient and efficient it seems that it would leave the heaviest of particulates in the bottom of the oil pan behind.
My question is have you ever used one of these Fomoto drain valves and are they safe. i saw your video on another variation of this idea utilizing a Schroeder valve and cap with a hose.
That's quite a bit different than the valve pictured in your original post. Since the one in the video has a cap with a seal in it, it is less likely to fail catastrophically. However I would still go with the simplicity and near 100% reliability of the standard drain bolt given the consequences of failure.
I would not use one of those drain valves. The results would be catastrophic if it let loose while you're barreling down the highway. If you're going to get under there anyway it's not that difficult to use a ratchet or wrench to R&R a conventional drain plug.
I agree with @ChuckTobias. I understand the convenience, but it literally only takes one failure and it's a catastrophic result.
