FWIW (not much, I'm sure ), I have done a lot of my own research into what sort of oil & additive package is a good match for my Challenger's usage. I've ruled out a number of name brand oils for different reasons (more than I can go into here) and will be giving Amsoil's Series 2000 20w50 a try. It's neither the cheapest nor the most expensive, but it's what I'm looking for from the standpoint of viscosity ratings, TBN level, anti-wear additives, etc.
