So what oil is good for us to use in our street motors. I have always used Castrol 10w-40. No good anymore?

This is supposedly a real concern on engine/cam break in...but I use Valvoline Racing all the time which has a good amount in it..GM engine oil supplement also is supposed to have plenty of zinc but don't quote me on it.
