oil filters remove oil additives?

This was a topic at lunch. Apparently a big name cam company had an issue with a camshaft going south and they blamed the oil filter. It was stated that the oil filter was removing the necessary additives to prevent premature wear. Like many of you I have read the information provided on zddplus.com. I beleive it isn't right to name either company as they have no reps on this site. I am curious to hear your comments!

thanks

I have heard many times that Moly can be filtered out, especially when a high density filter (like a "Pro 1"). Edit: "Pure 1" not Pro 1. Not sure about Zinc/Phosphorous though.

And I know Comp Cams additive is a megadose of Moly, not zinc.

i used zzddplus in my motor when i broke it in. i also checked the filter and didnt find any obvious signs of additives. but most importantly, my cam didnt flatten

This filter was sent to an outside lab and from what I understand,the anti wear additives like Zinc and Phosphorous were filtered out. Myself I just can't beleive it?

we need to know what filter it was. maybe it is some high tech microparticle filter. but I cant believe that a filter that lets oil through would filter out the zinc and phosphorous seeing as these particles are so tiny.

lets just say that you can buy this filter at any Napa store. This is not a fancy filter! I am no chemist but I beleive that this is a bogus statement as the cam went sour and someone is looking for an excuse.

If filters filter out the additives why wasn't this a problem before the additives were removed from the oil?

A Napa gold? You really need to tell so that we can make all types of assumptions! . Seriously, though, if its a two stage like a Pure 1 maybe it can happen. Different filters DO filter out a different size 'mininum particle' size.
Also I have heard (don't know though) that Moly is a bigger particle than zinc.
Its also said that Zinc blended in my the oil 'manufacturer' tends or can be a smaller particle size than zinc additives. True? I don't know.
I do know that Comp Cams additive (again Moly) is pitch black, ZDDPlus looks like honey colored oil. Not sure if thats indicative of anything, just pointing it out.

With my ZDDPlus I run a Wix or Napa Gold filter.
