Seal Conditioners in Redline/Amsoil vs M1 HM

[MNJ85]

Hello gents;

I posted another topic here about what oil would be best for my car and I have now decided what that is .

What I would like to ask, for those who know, is how are the “seal conditioners” in Amsoil or Redline compared to those in M1 HM? Do either one of those have robust seal conditioners as those advertised in M1 HM?

thanks for your help
