Teflon is not dissolved in the oil, it's a suspended solid.

Most who use Teflon loaded oil don't realize that the larger particles are
immediately pulled out of their oil by the oil filter. And the remaining
particles are so small that they pump harmlessly through the engine's
bearings.

But there is real danger in some engines of the stuff piling up at the end
of oil galleries and oil starving bearings. These engines use partial flow
oil filters instead of full flow oil filters and the partial flow systems
let the larger particles, the ones too large to pass through a bearing, on
through to cause damage. Can you say "VW Air Cooled?????"

And the statement that Teflon coats your friction surfaces is pure BS.
Teflon is so slippery that it won't stick to anything but itself and
manufactures have to use a special process just to apply the stuff to your
frying pan. They have to start by roughing the surface then they apply a
very thin layer, bake it on, and then they build up the Teflon up in
alternate spray / bake cycles. The statement that Teflon coats your friction
surfaces why SLICK-50 lost their lawsuit & is why Dupont tried to have them
remove the Dupont name from their product! Dupont was afraid of a secondary
lawsuit because they knew better - they designed Teflon and are familiar
with all of its characteristics.

Either no benefit or actively bad, likely the latter.  DuPont tried the get
the Slick-50 people to take their name off the product, dunno if they
succeeded.  I believe they still sell the PTFE powder to them though, tsk
tsk.
