The zinc in the STP can contaminate the turbine oil. I just use turbine oil on the bearings.

They STILL sell STP???

First of all, Zddp has been used as a primary AW additive for some time because it is cheap and effective.
There are a lot of components being devloped and have been developed to replace it. In the Science and Technology section, you will see an article on Boron, Calcium, and Antimony AW adds.
The big push is to use new non-metallic organic AW adds and new natural esters, such as found in
http://theoildrop.server101.com/ubb/ultimatebb.php?ubb=get_topic;f=4;t=000056.
ZDDP levels will be reduced to approx. 600 ppm in the newer oils, but Boron and concentrated, high-tbn Calcium adds are already taking over as Secondary AW adds.
A fairrly recent paper by a researcher at Lurbizol has found that 0.05% of ZDDP is about as low as an engine can tolerate without having secondary AW adds.
So what is your primary question or complaint?

STP is primarily a high molecular weight OCP with some ZDDP. And so is Wallyworld's Oil Treatment; they are almost identical.
There are various "flavors" and molecular weights (viscosities) of OCP's and some are used as VII's.
This product and the "Stop Smokers"
http://theoildrop.server101.com/ubb/ultimatebb.php?ubb=get_topic;f=5;t=002189;p=1#000021
are simply high molecular weight Olefin copolymers.
Thanks MolaKule. Is always good to have an Chemist/Tribologist in house.
That's the funniest thing I have heard here in a while. If a little is good, a LOT must be better!
SFR uses a better additive than those mentioned its only mined in three places in the world and is a direct replacement to lead is found in shotgun shot and pepto bismo. Its the only non-toxic safe additive left although boron is good this product is far better than boron.
To bad lead isn't being used anymore it was the best and still would be the best if used in oil and gas.

The Holy Grail, Hummmm. Okay.
Why is every post about additives NEGATIVE? I'm getting tired of it is there any POSITIVE stories about additives.

I had a truck many years ago that needed a new timing chain... you can find some posts here a while back if interested.
I went WELL over 800K+++++ miles with a timing chain slapping, tapping and dancing under the VC
And among other things, I used a lot of STP with a lot of M1 and a lot of Kendall and a lot of graphite (ARCO) and whatever I found...
I did find a mix of some Moly and Stp and Varied Motor oils that tamed the noise on the dying beast... and for whatever its worth it survived all those miles before I got tired of looking at it and sold it when the clutch went.
Besides that, WhatZ ZZZZZzuppp?
When I use to rebuild motors ide use a 50/50 mix of STP and 30 weight oil as an assembly lube.
Salsahh, we're not the only ones who are neg. about most adds. This is from the SFR site. "Once again, be very careful in selecting a lubrication additive. Most reduce friction, but they have potential negative effects. Most friction reduction products contain solids, resins, high sulfur content, heavy metals, etc. and are not completely compatible with today's engine oils. This is a reason the manufacturers ask you not to use additives. Most of these additive companies make false or totally outrageous claims, and it is very expensive to disprove the claims made."
SFR talks down only the negative additives that everyone else has found to have negative side effects. read carefully and listen to tkeith he's on to something that i Know NO BODY has talked about and the potential is the wave of the future.
I guess its just as bad as some of the amsoil marketing but both amsoil and SFR are telling the truth sometimes it hurts sometimes its positive i'm looking for the positive in additives.

good vibes i truly believe that the oil guys are using this to their advantage and only furthering their cause and not all of them are after your best intrests. Why are the oil guys looked at as saints and additives are the enemy when they use them too?
