Zinc oil additives

My Dodge is a roller engine so I don't think too much about ZDDP for that car, but in my 85 Celica Supra I use Mobil1 0w-40 full synthetic. It's on the shelf in the local parts stores and is not expensive. I would use the 15w-50 if I could find it locally, more for the extra viscosity than the anti wear agents.
