My HD shop manual says "Apply Loctite Thread Sealant with Teflon 565 to threads". This is NOT a thread locker.
I've never used any kind of thread locker on my drain plugs and in over 300,000 miles between three different big twins never had one come loose.

The factory puts white Teflon sealer on the threads, the dealer sells it as Loctite 565. I use it on all drain plugs, never a leak or problem.
I think if you buy a new drain plug the white Loctite is already on it.

I never used Teflon Tape or sealer of any kind on my Drain Plugs, just the O-Rings.

I never have. But whenever a dealer has drained/replace fluid for whatever reason (I.e I'm on a 7000 mile trip) I notice next time I drain, they had used the white sealant (which is not a thread locker)

Teflon tape when I do my own oil changes.
The dealer uses it too on the softy that still goes in for work.
I don't know if all dealers use it now, they never use to, but I guess if Harley has changed it's best practice and updated it's dealers they will.

If you tightened it until your elbow clicked, you're good to go! That plug is NOT going to vibrate out.
