Have a JT with the 3.6. Been using RP since 500 miles. Currently at 13.8k. Switched over from API RP to HPS RP at 8k. Seems to run very smooth and idle a little lower. I lknow HPS has the Synerlec and higher ZDDP. Question is the HPS much better than API RP or other API rated oils?

Nice Jeep; great colour!
Unless you race it off-road or really beat on it, any API full syn oil should be more than adequate. The 3.6 isnt hard on oil.
 
Royal Purple API pcmo is a excellent oil, if out of warranty the HPS may have better protection, if still in warranty (i assume it is) the API will work perfectly fine, what viscosity are you using ?,, you may get a lot of negative comments on RP on this site only for no reason.
