Asking about oil is the worst thing you can do, its a never ending battle between those who use and believe in additives, and those that don't build engines. It always come to this, every single time.
10-30 is a good all around oil, and with your mileage, you made a good choice. I not asking what brand, its your choice and it will just add fuel to the fire.
