I have 600 miles on my 2006 CTS and have noticed the initial start up oil pressure will be 70 psi and initial in town driving will cause the pressure to touch the 80 psi mark. It will eventually drop to 60 psi after engine warm up but these pressures seem high. Air temp in the 50s-60s. Should I be concerned?

Cold oil is thicker than warm oil. It sounds normal to me.
