Any manufacturer that you know of who publishes these results e.g. peer reviewed journal? Somebody had posted Chevron's study but that was at least two decades old and it was NOT the test as you described.
I am not trying to be wise guy here but apart from Chevron and 3M, I see no other manufacturer who might be even be conducting any of these studies let alone publish them or provide the results to us on request.
I do not think your suggestion is practical.
