The answer to this question may be obvious to some, but I wanted to see if my understanding was correct.
As I understand it, calcium and magesium are typically the additives used for acid neutralization, and high levels of these components tend to correlate with a high beginning TBNs. But when looking at UOAs of oils that have much-depleted TBNs, the levels of calcium and magnesium are not that different from fresh oil.
I assume this is because when, for example, calcium interacts with hydrochloric acid it forms calcium chloride and the tests run by Blackstone and others still detect the calcium. In other words, the calcium is still present, but not in a form that will allow it to neutralize more acid. Does this seem about right?
Thanks.
