Tony, take a look at the mechanical oil pressure gauge in your engine bay, and compare it to the dash unit. We have seen a significant variation, usually on the low side between the mechanical gauge and the electric dash gauge. There is a sending unit located next to your mechanical gauge, and sometime these can send a false reading if the orifice gets clogged by debris. Also remember that your actual viscosity will drop with an increase in temperature. One other thing to check is to make sure you are not getting fuel in the oil, as this will reduce the viscosity, and lubrication quality of the oil. If you notice an increase in the oil level, you may have an injector problem.
