Oil drain gaskets - best material

[Mustang5L5]

WHat gasket material do you guys use for your oil pan drain plugs??

Hard to beleive, but I still have the original gaskets as far as I know on my drain plugs. I need to replace them. The originals are plastic.

Right now i have the blue neoprene stye gaskets, copper gaskets and a couple of new plugs plugs that have molded on rubber on the ends. Unsure which to go with.

What do you guys use that reliably does not leak?

EDIT:

NVM, found the stock OEM gasket is a Fel-pro 70822. Just gonna pick up 2 of those and run them.

dead soft copper or the molded blue rubber would be what i used. ive used them in the past with out issue. the volvo uses a aluminum or steel not sure which (the company i order from ships the with the filter) and they have to be replaced every oil change which i think SUCKS
