4.0 liter oil pressure

Hi guys. I have noticed that the oil pressure in my TJ starts at about 40 psi, but after a few miles on a hot summer day, it will drop sometimes down to 15 psi at idle. It is always steady at 40 while running and when the outside temperature is below 50. Is it right for it to drop that low? It usually sits at about 25 psi on an 85 degree day, at idle. Also, whatever the outside temperature is, the engine coolant gauge always reads about 200 degrees. Is that too high? Thanks for all of your help.
