PTFE is a solid particle that clumps and expands with heat. It absolutely
cannot bond to an oily surface. The best you can hope for is that it will
clump together in large enough chunks to be captured by the oil filter
(blinding it) before it gets into the galley. In the galley it is quite
capable of creating large enough clumps to block oil flow and stick rings.
In every lab study done with PTFE additives they resulted in no benefit at
best, to extensive engine wear at worse.
Slick-50, currently owned by Quaker State Oil, has been prosecuted by the FTC
for fraudulent and deceptive advertising. Dupont originally sought a
prohibitive injunction against the marketing of PTFE (Teflon being their trade
name for PTFE) as an oil additive because they knew it was unsuited for this
application, but the courts ruled against them.
