I like a oil with a good detergent package, keeps things clean ... I'd go with Chevron Delo-400 in a 30wt.
Oil is kinda up to the guy buyin it...Some like Penzoil, some like Valvolene, some like the synthetics...Some say only Mobil 1....Well, it yer Jeep, buy what YOU want.....
Just drive it..... "BH"
