But why not? (apart from hassle, mess and health issues)
There are fairly high performance spun polypropylene filter candles for potable water filtration widely available here. Media not expensive but maximum temperature is 60 degrees C so I'd expect it would be very slow with motor oil.
I thought that I could perhaps use something like this with seasonal oil changes between, say 40W and 15/40 giving the oil six months on, six months off which might be long enough to filter it offline.
Dunno if I can reliably remove oil via the drain plug without contaminating it though. Might need to pump it. Would also need to dumpster-dive the filter holder(s) since I'm not going to buy one. The ones I've seen chucked out so far .have been institutional and too big.
For the OP, you don't need a very fine filter to take bits of PTFE tape out, since they're flat. Maybe the foot end of a laddered pair of tights (er...pantyhose in American, I think. Nothing to do with Robin Hood)
Tiny pieces that might get through shouldn't be a problem. You've just made yourself some Slick.
