This is an extremely interesting document, so thanks for the link. However,
it dates from 1999.

The last paragraph is significant, in that the authors note their findings
have not yet been fleshed-out or verified by additional testing, and are
based on limited data.

Quite a lot may have happened in the succeeding ten years since that doc
was written, but there's nothing new on the SwRI site.

And this: "...many oil chemistries require time and temperature to enhance
their effectiveness".

I'm really curious what real-world lessons those statements and test
results have for us car owners. They have a contact page, I see. Next week
I'll submit a few questions to them in the hopes of getting an answer.

Stay tuned...
