Higher oil pressure from thicker oil isn't necessarily a good thing. The higher pressure just means that the oil isn't flowing thru the engine very well. The pressure rise is due to reduced oil flow which isn't necessarily a good thing. The bearings need some oil flow across them to carry away the heat so less flow could be bad.

60 psi with thick oil and a standard pump could be a lot less oil volume than 60 psi with thin oil and a HV pump. People tend to focus on oil pressure since almost everyone has an oil pressure gauge but oil flow is also important.
