If you track your car, then just use the gold castrol bottle. Pay a little more for piece of mind that the oil is branded to "last longer" although they stopped making that claim.
I've used nothing but castrol edge in my car and it always runs smooth throughout the oil change interval compared to using conventional oil.
Mobil 1 extended performance is just as good, too.
