Government Laws The government of the USA has mandated the removal of "anti scuff" agents in most engine oils, many years ago.
MANY posts speak about rocker arm/valve tip wear and some about oil pump "G" rotor wear, etc.
When an EOS additive is added to this "modern" engine oil, the life of these type of items can be more than DOUBLED !
Let is find which one will work best ?

I DO know they removed zinc compounds a while back.
Is there a practical way to replenish that?
I also realize there are a huge number of those compounds, so one might be judicious in their use

I used Schaefer’s ZDDP additive in my circle track days. As of late, I’ve used Lucas ZDDP additive in both a truck I have and my Chevelle, before I switched to Gibbs LS30 in the Chevelle, which has ample ZDDP for my usage. A point to note here is that neither of these vehicles have catalytic converters. Zinc is hard on the converters and will ultimately hurt them. The clean air folks tell us that the zinc is also harmful to the atmosphere. Not trying to turn this into a EPA or political discussion, so let’s not go there, and keep it on topic.

While doing the best things for my engine is very important to me, it is just as important to keep my vehicle able to pass inspection by not ruining the converters.
Sooo... the next question is- Is there an additive that can approximate the anti-friction properties of ZDDP without compromising emission gear?

Thanks for those VERY valid points Scott!

Teflon for ZDDP replacement ? I have used Teflon, EXTREMELY FINE, in engine oil.
That brand was Petro Tech.
I also used this in Two-Stroke fuel.
I believed this made the engine oil/fuel more slippery.

I used Slick50 back in the early 90’s, which was Teflon. Lots of folks laughed at the product, but we tested it and found power. With a carbureted application, you could add it to your crankcase, start the vehicle, and the idle would jump up 50 rpm after about 30 seconds and stay there.

I think one concern back then was that the Teflon would just end up in the filter, possibly clogging it.
I wonder how much improvement there was to fuel economy from the reduced friction.
I just googled PetroTech and Slick50. Slick 50 still is being sold. Petro Tech is in the wind.

I'd heard from too many mechanics in the '90s that the teflon would actually end up hardening with heat cycles and lock the engine.
EDIT: As far as supplements go, I don't use any in my two vehicles right now, because both or them have rollerized valvetrains, and Iuse Mobil 1 in them (flame suit on).
What I used to use when I drove a flat-lifter truck (about 15 years ago) was the GM EOS. I had read (on a Ford site, of all places) that it had the highest zinc content available.
Later, I also read that STP Oil Treatment was the same thing.

I'm not calling you a liar, but I've never heard anything good about Slick 50 (except from people who were trying to sell it).

Fwiw, I make my own assembly lube, using STP oil treatment (blue bottle) as a base.

Teflon Coating Methods Hi Gary, I found the Teflon "coated" bearing surfaces to be of good use.
Somewhat as in a frying pan, a no stick surface !
There is evidence of faster oil flow, good for cooling.
