Then there is Hyperlube (additive). It is a Polymer Ester for Extreme Pressure. It's an Anti wear additive. Check Ebay or Oreilly's Auto Parts. There are several threads about HyperLube. It's Good stuff!
Please post some pics of your Challenger!
It's not a group V synthetic it has 10% or less group V and 90% "synthetic basestock". As for HyperLube I will not recommend marketing for an lubericant.
OP use whatever 40 grade your comfortable with no reason to mess with additives.
