different viscosity in oils have different rules for formulation especially anything heavier than a xxW30. the minimal mpgs from thinner oils is not as important as the protection afforded by heavier oils IMO even thou those formulations may use some better base oils

Why are you bothered about ZDDP levels? Do you run high spring pressures on flat tappets or another reason?
