Sorry to move in on the thread, but does anyone know how the CompCams additive works?
I used Comps additive in the first two crankcase fills of my Voodoo cam swap. Cam is alive. I have heard, but I am not sure, that Comps additive is actually a megadose of Moly, not zinc. And there are some people that state moly can, in fact, offer the protection we need. IF thats true, I don't know, but the stuff did work for me.
But now I am using ZDDPlus. I also toss in a bottle of STP red--not so much for the zinc, but rather the 'cling factor'--I believe a cam that has sit for weeks in an engine is more likely to have lubrication clinging to the lobes with STP. Maybe, maybe not, but I sleep well at night.

Here's another product that increases the ZDDP in oil. www.cam-shield.comThe Hughes additive appears to be moly, I think it's the same for Comp Cam.

I called Mobil 1 and their 20w-50 extended service synthetic has 1200 ppm zync and double the supersyn of their regular synthetic. I run it in my car and my sons car (which has flat tappet hydraulic cam)and have had no problems. Mine has a solid roller but I like having the extra slick stuff to keep things lubed, plus both of our cars see a lot of street use.

True, but one must take into account that oils are constantly being reformulated and levels of zinc and phosphourus are changing. Oil companies can (and do) make changes 'between' the rolling of the API or diesel specs--So a SL,SM, CI or CJ oil that tests ok today may not have the same levels next month.
Its a real risk that is part of the problem.
I would not however, include some brands such as Brad Penn, Redline, Amsoil etc that are specifically marketed to us and the zinc issue discussed within their marketing programs.

When discussing oil additives the issue of compatibility between the oil and the additive remains up for debate.
In THIS bench test for example, it is shown that adding a well known oil additive to gear and motor oil causes oil foaming. How much this bench test can be related to real world use remains unseen. But one thing is certain; adding an oil additive to an already blended oil product shows an effect. In the case of this bench test, the effect is not a favorable one.
I visualize it this way. Consider a quart of motor oil as a container of chemicals, or more exactly, balanced chemicals blended by a Chemist or Tribologist in a laboratory with carefully selected chemical components. Some of these chemicals are known to complement one another. Sometimes the blended result is positive while other times it is negative. Comparatively, when you mix two separate oil products, blended by two separate companies, what will the outcome be? Will it be positive OR negative? The answer to this question is obscure at best and outcomes may vary. The next question could be, am I willing to take a gamble and blend two separate oil products?
Another area where this topic gets clouded is the issue of extreme contact loads in performance flat-tappet camshaft applications. In recent times, many of us have experienced, heard, read, or know someone who has had a flat-tappet cam failure. Many times this has been attributed to such things as lifter quality, poor cam metallurgy, and of course the lower zinc/phosphorus content in newer API (SM) rated motor oils. In the latter possibility, the temptation to utilize an oil additive to supplement an apparently weak lubricant is understandable. However, I believe that with a little research, it can be reasonably determined that a properly blended motor oil will contain the right chemical properties which can provide optimal camshaft protection without the need for additional oil additives.
Conclusion –
Rather than spending hard earned funds on an oil additive which may give questionable results, use those funds towards a properly formulated and proven motor oil; a balanced lubricant.

While I agree with this statement, I have not been able to fine "good" oil in the lower viscosities that are sometimes needed, like 5W30. I know that the newer engines are rollerized at many of the wear points where zinc etc helps, but there are lots of other metal on metal points too, like rings, pushrods, oil pumps, etc. We just don't know yet if engine life is going to be shorter with SM oil, and won't for a long time. Because of this, I like to get some additive in the oil weights that don't come in the good stuff, particularly on things like our camper van (6.0 Chev in a 3500 extended van, hauling around over 8000# all the time) It needs to be on 5W30 to maintain the 100K warranty.

Oil additives typically increase the viscosity of the oils they are added to. So if your goal is a 5W-30 oil, it may end up much thicker after the additive is added.
Below are a couple examples of high zinc/phos oils that are in the lower viscosity spectrum you are after.
AMSOIL Series 3000 100% Synthetic 5W-30 Diesel Oil (HDD)
• (HDD) Zinc = 1379ppm
• (HDD) Phosphorous = 1266ppm
AMSOIL Dominator® Synthetic 5W-20 Racing Oil (RD20)
• (RD20) Zinc = 1676ppm
• (RD20) Phosphorous = 1509ppm
