Meh, I just pop a wine cork in there and I am good to go for the next 5,000 miles.

I would be hesitant on the "hammering" but would try the extractor first. Only $16 from Amazon and always good to have.

I had to do all of the suggestions…extractors… I think I had to order a #6. Stuff at local places were too small. I think what finally worked was hammering in a Torx and slowly backing it out. It did take me an hour plus. Just take your time. From all of my attempts I basically had a round hole. I think dealer or PO tightened it way too tight. I am now using a LN.

A #6 extractor will work. Super easy.

Thinking I’ll be in this boat next oil change. Torquing the plug in last oil change my socket stuck and I had to tap on it to get it out. Sure sign the hex is starting to strip.

I got a spare drain plug and a variety of extractors in the toolbox for this contingency. Next oil change it’s getting a new drain plug either way.

The coolant and transmission drain plugs are aluminum hex sockets as well.

My socket gets slightly stuck every time I torque the plug in after I change the oil, but I use a new drain plug every time I change the oil also. I don’t think the 8 mm is a perfect fit, but that’s what the Porsche manual says to use.

I mentioned in post #9 above that although a 8mm hex typically works I feel that a T50 torx is a tighter fit. On a previous oil change I experienced some issues with rounding and feared I could not remove the plug with the 8mm hex. I used a T-50 torx and it was a tighter fit and removed it with no issue. I did not have a spare and reused it using the T-50 and replaced it the next time with the LN magnetic plug. This upcoming oil change will be the first time removing the LN plug so I will decide if I should reuse it of go back to a new OEM plug.🤔

A bit late as I forgot to post this video...

Sometimes I wonder how that is even possible if you are using a quality tool of the correct "metric" size (not a close SAE equivalent) and you are turning it in the correct direction, but here is a video I came across on YouTube that is always good for a chuckle.

BTW a couple of years ago I had the same issue on a friend's 997 when I did an oil change. The hex was so screwed up that I could only get a hex bit into it by maybe 3/16" or 5 mm deep. I really have to wonder who installed it last and got it tight enough that way. Simply amazing! I got it out carefully using a chisel. Then he gave me two aftermarket magnetic drain plugs that would not fit even though they were an M18 x 1.5 thread. Go figure, so much for "standards". Good thing I had a new spare oil drain plug at home that he never replaced.
