OIL Additive Importance

I read an article about the aftermarket camshaft companys having pre-mature failure because of the Newer OILS not having the additives they once had. Article stated since the EPA got strick on them using Zinc that they have removed it and that has caused some problems. One of the reasons given for removing Zinc was, it was hard on Catyltic Converters. Also, The article said that one of the oils being Shell Rotella that once had Zinc is now with NO Zinc additive in their oil. My question is if you are using Shell Rotella what additives would you use and how much? :confused
