The 5.3 oil capacity is 8 quarts. Sorry I meant to say I purchase 2 Kirkland 5 qt jugs because it is cheaper.Since they hold 10 Quarts of oil don’t throw away you money. First one early and then every 5 thousand. These are GDI and won’t support a long oci. I use Supertech and Kirkland and the engine seems to love this oil. Oil report came back great.
