Don't run thicker oil to band aid a pressure problem. Thicker oil will read higher pressure only because of the restriction to flow which means less oil moving through the bearings which means more heat.
I'm with Gerald sounds like a relief issue. Suction side would usually show low pressure when cold since the oil is thicker the pump will pick up more air than oil... not always though.
First thing I'd do is talk to Alvin and see what he recommends since he was just in it.
