A great conversation and thanks to all that are chiming in.
I have already reached out to Amsoil about adding Bio/Tech Lubegard to their products and I am waiting for their reply. I will update once I receive it. I have decided NOT to reach out to Lubegard despite your recommendation,
@Burla, because they state directly on their website "Blends with ALL motor oils currently produced, including API; SJ, SK, SL, SM, SN – SN+, SN, CH-4, CI-4, CI-4+, CJ-4 – CK-4 motor oils". So I can hear it now: Amsoil says "NO, don't add anything" and Lubegard says "YES, add it to any and every oil". Enough already!
I am in the agreement that a proper oil shouldn't need any additives. With this in mind, despite my Lifetime Warrantee and therefore my reluctance to spend an exorbitant amount on frequently changed engine oil, I think that my best course of action is to make the move to either a Redline or HPL product. As I mentioned in an earlier post, I am not married to Amsoil; while I think they produce a quality product, their recommended product for my 6.4 Hemi is a letdown. Sure, I could try out brand X, W or Z in their different viscosity grades but I have other things to do with my life so I am really not interested in doing this.
So if I am going to go all the way, I am leaning towards HPL. Now the fun part; which oil? No VII, Passenger Car, Premium Passenger Car, Premium + Passenger Car or Super Car? And what viscosity?
I never knew that owning a Hemi would be so complicated
