I would like to know if you mean you learnt or I learnt. I learnt nothing from the mobile screen shots you posted, except to wonder why I'd never want to buy in on these so so mobile social. I have been using the same plug since day one and it shows no sign deterioration. Like they say, don't believe in everything you read including mine.

I bought my 2002 in Oct of that year
I learned the bung was a one time use item way back then ... nothing new here. The fact that majority of DIY folks re-use doesn't make it right
but I too changed to Fumoto and the issue became moot
Haynes for GEN1 in the section for oil change procedure
step 12: Discard the drain plug, a new one must be used. Note that the sealing ring is integral with the plug.
In other words the equivalent of replacing the crush seal is replacing the plug/seal unit

Most people understand the facts and don’t argue with them. Mini Cooper/BMW recommends a new plug every time. Wait until the plug you are using strips and then come back and tell us how you fixed it. Most people care enough to follow the directions. I hope no t everyone disputes the facts. Good luck on your old drain plug

I see that you have globs of auto mechanical experience. No, no one have used this, and no one worth their DIY mechanic salt has done oil change and clueless enough that you are only supposed to buy a new drain plug every time. I avoid any products that spell EZ or as seen on TV and that is a hint, my man.
Oh, and BTW, the new plug that you buy every time for $5 is likely not a precious genuine BMW part with the molded rubber around steel integral washer. Look closer and it is likely a aftermarket clone that is constructed differently. BMW ones cost closer to $15.

Hey super mechanic. You do what you want to do with with your vehicle and I will do what I will with mine. You keep the personal insulting comments to yourself. Just because I choose to reuse my oil plug doesn’t mean I’m cheaping out or I’m a wanna be mechanic. When you make blanket statements on a blog they are directed towards everyone. I’ve reused the same oil plug many times. Maybe those having issues are torquing them down a little too much.

Or if you flip the ring over the damaged side now presses against the sump. This can damage that critical face against which the sealing ring seals.
Porsche techs tell me they can always tell when sealing rings have been reused. There is an oil stain around the drain plug and on the engine sump.
You should always use a new sealing ring. It is the sacrificial item in the drain plug/oil sump sealing. I always had extra rings on hand for just in case. And I carried a spare drain plug in each car's center console for just in case too.

The Porsche drain plug sealing ring is *not* a crush washer but just what it is called. Sealing ring. The ring acts to seal the drain plug to the oil sump. The ring is made out of a pretty hard metal. If you look at a used one you can see the drain plug has put an imprint in the ring. If you reuse the ring with the damaged surface against the drain plug the drain plug may not end up at the same position as before and the seal between the drain plug and the ring may leak.

So you carry a spare drain plug in each car's center console just in case? Must be a comfort thought that you have a spare one on hand after the one on the sump fell out. Me, no. I like living on the edge and don't mind a bit of oil stain around the drain plug should it fall out on the road.
