Default Interesting oil pressure change

Before my H/C swap on dino oil the car was holding (mind you it was the dash gauge) 40psi cold and around 20-30 hot and would run up to about 50 under throttle. After H/C swap I swapped to identical grade Mobil 1 and now it's holding 60+ at idle cold and 40 hot and shoots to around 70 under throttle. lol is there such thing as too much oil pressure?

Thats fine Ive always been told 10psi per 1000rpm So if your at 30 or 40 @ idle & nail it to 7grand Youll be fine @ 70psi
