GNocide and Wells,
I was in fact reading this whole thread from the start and appreciate all the work Mr. Clark has gone through with his product. I was just trying to point out that there are not only different types of ZDDPs (i.e. Aryl ZDDP, Alkyl ZDDP, etc.) that you may have to take into consideration in mixing with a particular brand of oil, but also you need the correct concentration based on the particular brand of oil your mixing it with. For example, oils with lower ash levels need more ZZDP to provide the same level of protection as a normal ash level oil mixed with ZDDP.
Also, I would be hesitant in putting any additives to oil. The oils are formulated from the manufacturer with a fine balance of additives (anti-foam, corrosion inhibitors, anti-wear, detergent / dispersants, oxidation inhibitors), and using this additive could upset the balance resulting in reduced performance. In other words, its true that todays oils have virtually no ZDDP left in them, but todays oils have been reformulated such that just simply adding this stuff to a modern oil may not be the equivalent to when this stuff was already incorporated in yesterdays oils right from the manufacturer (i.e. the manufacturer had the correct fine balance of particular components in their oil so they perform correctly). I guess at this point that until someone comes out with an oil that has the correct ZDDP level for our daily driven cars, we have no choice but to put this additive in and just hope for the best...
Im just thinking out loud and could be totally wrong in my assumptions, but this was just my thoughts....:redface:
