Installed hemi pan today ( have oil question )

[69chargerR/T]

I installed my hemi oil pan today,every thing went well I went to napa to get some oil and a napa gold filter (as Ron recommends) I was going to get valvoline VR-1 20-50 but they were all out So I got some napa 15-40 fleet oil I've heard that has a high level of zinc, do I still need to put in an additive to raise the zinc level The oil is rated CJ-4,CI-4,CI-4 plus,CH-4,CG-4,CF/SL. I left the oil a 1/2 qt. low so I can put an additive in if you guys think I need to add one Any info would be great thanks Alan

I run the VR1 oil in my Charger and I add a bottle of EOS too. Better to be safe than have a flat cam......So yea I would add some if I were in youre shoes.
