What should the oil pressure be when I am driving my 2008 H Hummer?

mine is usually between 30 to 40 psi once at operating temp and driving around town, prior to that when cold its at 55 psi which is at the pressure relief for the VVT

Mine is 35 to 40 from hot idol to cruise. At start up cold it's about 50 PSI or so. I'm using Mobile 1 10W-30 the recommended Viscosity for the 6.2 2009 Flex Fuel SUV.
