60/80 psi. cold start is typical. 10/20/30 psi at HOT idle in gear is good. As was said as long as it rises with rpm, all is well. 10/30 oil is all you should need to obtain these numbers
Hot idle is AFTER being driven 20 to 30 minutes on the highway, then coming to a stop.
Hot idle IS NOT as soon as the temp gauge reads 160/180 sitting in the driveway, doing it that way, the coolant may be warm/hot, but the oil is still cool. The oil gets hot from engine load/work.
