API, I imagine is on the bottle, and would bet it is whatever is current for that particular grade.
Flash, on the MSDS is -20f
Your centistokes measurements you will need to decide which oil, and call the company, and see if they will supply that, although I believe it is also part of the API cert the ranges that they fall within (Dieselpower? )
VI, again, I believe that is factored based upon the particular weight of the oil you are working with.
Pour Point -20f off the provided MSDS
TBN, again, I think you need to narrow your search to a particular oil, and ask the company if they will provide that info.
They wrote the MSDS to cover a broad range of oils, and some of the questions you are posing will have to be adressed to a particular one.
For me, if it meets the API spec grade, etc. I am pretty comfortable with it. But I am not sure exactly what your needs and desires are.
