Default Update on Oil Pressure

Yesterday, I flushed the engine with GUNK-brand engine flush and then did an oil change to 20W50 Valvoline Max Life. We're now running 15-16 PSI at idle, when stopped, once the engine is fully warmed up. No more idiot light coming on. Cruising RPMs has 45-60 PSI oil pressure, once warmed up, depending on RPMs.

This is exactly what I did on the AMC 360 in my Grand Wagoneer, 5 years ago, when it was running 7 PSI at idle warmed up. Got it up to 12 PSI and ran it for about 15,000 miles with 20W50 (Amsoil)
