Oil Changes- Why does Porsche Recommend Replacing Oil Drain Plugs?
I have never heard on any other car having to replace the oil drain plugs at each oil change . The crush gasket, of course.
The drain plugs aren't expensive . Just curious why this is recommended?

It is a plastic part that has a tooth that passes over a ramp that holds the plug tight in place.
To remove it the tooth get bent a little and may not engage the ramp as well next time.
I have reused the plugs before, but have always checked to see if the tooth engages the ramp to hold it tight.

My oil pan drain plug is not plastic, it is metal . Specs call for 37 foot pounds of torque.
What part are you talking about that is plastic?
At any rate, the drain plugs are cheap, so I will replace at next oil change.

Well, I believe the issue may be the OEM drain plug is made of aluminum. The concern may be that once torqued 37 FT/LBS to the aluminum oil pan drain pan that it may "fuse" and cause problem removing.
I am no engineer, but I reckon I won't risk it for $5.

On my former Ferraris, I would order the oil filter from Ricambi. Always came as a kit with filter, crush washer and drain plug. Porsche appears to be the same.

My 991.2 has a plastic drain plug. Never seen one on any other car before. But I bought a bag of the replacement plugs cheap so no worries. Mine doesn't leak a drop.

You must have a 991.1. The 991.2 is plastic. I have no idea why you would have to replace a metal drain plug.

Yes, I have a 991.1. Sounds crazy though that Porsche went to a plastic oil pan drain plug . Perhaps , there was a trend of the aluminum drain plugs "fusing" themselves to the similar metal aluminum oil pan ? Plastic would not have this issue and understandably they would be disposable.

It’s actually pretty common. The drain plug is a consumable for a lot of performance oriented cars.

I have been running this valve for my oil pan. Game Changer for oil changes in terms of mess reduction and not needing to replace washers etc.

I don't get plastic drain plugs either. My new Bronco, and my Mach1 have them, and I was surprised to find one on my .2 Carrera T as well. I'm not reusing the plastic plugs on any of them! Guess I'm just glad my latest cars still need oil, and don't run on electrons...

See the videos below for the answer, a plug is only ~ $5 - just replace it:
