Warren Performance MAY tweak the additive package for the different brands they supply, and they would definitely be different based on whether they're Diesel CK-4 or Gasser SN API spec.
That's correct. Warren has various additives for whichever product they are bottling. I believe there's quite a bit of monitoring and testing involved to assure the proper blends. An insider told me that Mag 1 and Walmart's SuperTech are the same exact recipe. I've also been told that they bottle for BP (British Petroleum) at one of their other plants. I would like to think that if BP were allowing them mix and bottle their products they must know their stuff.
