Whats the deal with PTFE ??

Not sure what you are really asking. Dupont the manufacturer of PFTE or Teflon has determined it does not belong in engines. Period. However they are forced to sell it and thus companies who buy it to use in an unapproved application like an engine must call it PFTE, not Teflon.

Slick 50 and others probably still use PFTE as an additive.

Buy quality oil and forget the snake oil.
 
PFTE hasn't been under patent protection for years. Any number of cookware makers have been using it as a nonstick surface without paying DuPont anything or even calling it PFTE. Many of them have excellent name recognition - like T-Fal.

As for Slick 50, there was nothing that really proved that the stuff did anything useful. I got suckered into trying it out in the early 90s. The shop that did my oil change was willing to pour it in. The engine itself was OK, but after a few years I noticed some hard crusty stuff forming near the filler hole and on the filler cap threads. It was really odd when Quaker State bought them out. I also remember Slick 50 synthetic motor oil. It didn't claim to have any of the PFTE additive, but was an API licensed motor oil with the donut and starburst.

The current Slick 50 oil treatment doesn't claim to contain PFTE or any kind of solid.
 
Agreed. PTFE is good for a lot of things, but adding to engine oil is not one of them. I don't think Slick 50 even uses it any more.

It has been proven over and over that ptfe will eventually burn up and carbon an engine over the long haul. In the short term it does...NOTHING.
Tiny little roller bearing all over your cylinders. What a carp load.......
If it worked , ever manufacturer on the planet would be all over it.

Actually PTFE is banned from cookware after 2015.
 
There probably is some basis for its use - iirc, oil less compressors and similar equipment are coated/lined with ptfe.

That said, the temps of operation are vastly different, and so its presence in combination with combustion and combustion byproducts is suspect.
