For your climate, I would use 15W50 Mobil 1 or similar viscosity if you will never be in cold weather. It has enough zinc and phosphorus if that is your concern. Too much of these does not give you any extra benefit and just risk your catalytic converter. Change more often for IMS cars as well as S models and above to prevent bore scoring.
