I just bought this car yesterday. I'm wondering whether I should use a high mileage oil or if just put in the normal synthetic 5w-30?

My 5.3 motor in my 2006 silverado with 20,000 miles doesn't seem to burn any significant amount of oil. I'm at 6,000 miles since my last oil change with no top offs and it's still very close to the top of the cross-hatched zone on the dipstick. This is using M1 5w-30 extended oil.
