What you say about a catalytic converter may be true. If the material were Poly Iso Butylene there would be no need for such a device as the Poly Iso Butylene actually improves the combustion process. That's why I was confused when I heard that it was the additive. To settle this whole mess, I sent an email to the NASA test director asking him what the additive was. I also asked him if it was Poly Iso Butylene. Hopefully, I 'll have an answer early next week.
