It’s a good oil. I don’t know to which reports you’re referring, but the UOAs show it holding up well. I really don’t like the elemental VOAs that show “XX PPM of XX” because you really cannot tell anything from those.
The problem with that kind of analysis is that you only know the elements. It’s like knowing what letters are used in writing, but not knowing the words or the grammar. Additives are made from elements, but additive chemistry is complex. Additive performance, or effectiveness, isn’t a matter of element level, it’s the performance of complex chemical compounds.
Just as good writing is more than just how many of each letter is used, it’s a matter of how those letters are formed into words, and then how those words are structured and used together.
Saying, for example, that “Oil XX is good has lots of calcium” is like saying, “that’s a good news article because the writer used the letter “R” more than this other writer“… It’s superficial and specious.
