Heavy oil makes gauge read higher because there is less flow. Flow is what cools bearings, pistons and valvetrain. As long as you are over 10 PSI per 1000 rpm you should be ok. Above 60 PSI the bypass starts to open anyway. The vented oil goes back to pump inlet instead of to parts where it can lube and clean and cool them. Paraphrasing Dick Patterson’s Olds oiling presentation.
