Ive been told as long as you have 10 PSI for every 1000 rpms you will be ok, but I personally like to have more than that

Service manual specs 13 psi as being the minimum at hot idle.
When I first start mine, it idles at 50, and stays around 60 while driving.
When hot, it idles between 15-20 and when at speed is at 50 psi.
10w30 Mobil 1 high mileage and Mopar filter.
I ran Rotella T synthetic 5w40 once just to try it and my pressure was much higher. Hot idle was 35, and driving was 60. When cold I had 55 psi idle, and 65-70 while driving.
