As far as I know, the jeeps come with dino oil. As far as the warranty you will have to follow the scheduled maintenance in the owners manual.
I just take ours to the local Jeep dealer, they do the oil change and fluids and hand wash for $25, not worth me doing it at that price.
If you do your own service, keeps records and receipts...
