10W30 weight oil.
What does your owner's manual say? I would suspect it say's 5w20.
any kind you want to pay for higher grade usually goes further.
In cold weather 5W30, 10W30 for warmer weather and make sure that It has the API badge saying it meets current SM standards.
The grade A of gasoline is what Chevrolet recommends in the 5.3 liter V8.

The highest grade of gasoline doe chrolet is recommended in the 5.3 liter v8.
