I can certainly understand that stuff happens, but it is hard to understand how this happened. Don’t you wipe the contact metal down with a rag? I’ve never done an oil change where I didn’t do that which entails visually inspecting the surface. If the old ring was stuck to the surface, it would be seen and corrected.
Do you put a little oil on the new seal before you screw on the new filter?
As for the drain plug, I’ve never had one where, again, I didn’t clean the oil pan where the seal connects and then clean the plug very well before install. Which, I’ve always snugged the oil drain plug down by hand. I would never take a wrench to a drain plug that wasn’t snugged down by hand.
I get that someone in a high volume shop could skip these steps, but in my driveway, the whole point is to slow down and do it right. Of course the OP has learned that lesson.
