| The EPA has made a lot of additives that used to be in oils illegal. They only exist in race oils and diesel oils now. There's not actually a huge difference between T6 and race oils, but Amsoil/Royal Purple would rather you didn't know that. I can't really speak to T6's effect on catalytic converters, but doubt that running a high additive race oil is any different.
