Mobil 1 10w-30 & Delco PF61 is what I always ran in my '04 5.3L, Pulled the pan, Timing cover, & Valley cover off this past weekend getting ready for the transplant into a Camaro, It looked new on the inside! Zero varnish.

Stay away from Delco E-core filters, They are junk!, E-core filters generally have a "E" suffix....PF61E for example. Look down in the filter, If you see a plastic media support...It's an E-core, Metal support...Classic design.
