If it is a pipe thread type of plug, use a thread sealant called RectorSeal.
It is used for LP, Natural Gas and various types of petroleum joints. It is
gasoline and oil resistant and will stay somewhat pliable. Also, buy a new
plug. Those threads do wear every time you remove and reinstall. Make sure
to check that the threaded area of the oil pan is not cracked or breaking
away from the pan itself.
If the plug is a straight thread style, it probably has a flange that
requires a gasket. Some engines use copper or aluminum gaskets. Toyota used
to use a fiber gasket - that worked fine as well.

Subject: [TR] oil pan plug
Newly overhauled tr-3. Wrapped the oil pan plug with teflon tape and
tightened up to what felt solid. It's been leading while just sitting over
winter. Have a dinner plate size oil puddle at least. I purchased the Moss
ball valve type spigot to install so I won't need to bother the threads in
the future. I'd like to get a good tight seal on the valve. Looking for
suggestions on what to use for a good oil blocking seal. Just wrap with
thicker and thicker teflon tape? Is there a plumbers putty/caulk that might
work. If so does plumbers stuff work ok with the engine heat?
Just wondering
