After doing some research on the internet I found that the only product that has zinc in it made buy STP is STP Engine
Treatment With XEP2. That cost you $17.95. The $3 stuff which is STP Oil additive dose not state or to be found to have zinc. I believe the STP Oil additve falls under the PTEF catagory.

I have looked on the STP website and can't seem to find that they even have the engine treatment.

But I did find that the STP Engine Treatment with XZEP2 have got themselves in trouble.

Here is the oil additive I have been using when I can't find SJ/SL rated diesel oil.
http://www.stp.com/oil_additives.html either the blue bottle or red bottle.

STP has been around for more than 30+ years the regular stuff in the blue or red bottle is not PTFE. Teflon as an oil additive only came on the seen in the past 10 years or so.
