Amsoil oil enough Zinc?

[DJ1967Dart]

Greetings all, I recently acquired a 70 RT Challenger with a 383 Magnum and the last owner included a case of Amsoil diesel SAE 5W-40 synthetic oil premium API CJ-4. I was wondering if anyone can confirm there is enough Zinc in this product to use in my ride. Don't want to flatten the cam. Included is a picture of the box. Your advice is greatly appreciated. Go Mopar.

I've not used it, but a quick check of the Amsoil website indicates it is for 2007 and newer diesel engines. It is therefore an emission-quality oil. Why chance it? It would be a nice Christmas gift to a diesel friend. Amsoil makes a Z-Rod oil for your flat tappet engine.
