Copper sump plug crush washers

[LogicprObe]

I kept forgetting to buy a new plug for about half a dozen oil changes...........and now it won't come out! (spins around)
Not leaking (yet) but has anyone had any experience in this situation?

Most likely what happened is that every time you remove sump plug you over tightened it, more and more until the thread stripped.

You probably need to buy an oversized sump plug kit (eBay is your friend).
When reinstalling sump plug, use normal length spanner and think about it as it was just M8 bolt not M14.

It’s not unusual that I often need to reach for 600mm breaker bar and use a lot of force to undo some sump plugs, even the oil filters.

While turning the sump plug try to wedge the screw driver under the socket and apply the pressure like you would want to pry it out of the sump, hopefully it will come out.

Thanks.
That was what I was going to try at the next oil change.
Just want to be prepared!

I think you can buy a thing called a helicoil insert to fix stripped threads.HeliCoil

They're good for the blind holes, not so good repairing thread in the sump.
