Regular unleaded will work for any stock Jeep. I assume you are running a 4.0L (6-cylinder)? There is no gain to be had for burning the expensive fuel unless you modify your throttle body or install serious performance-enhancements to your Jeep. Consider a fuel additive every 5,000 miles or so to keep your injectors clean if you really want to keep your fuel system at its peak.
