Alight fellas, i got a set of sunpro gauges to watch my vitals and i recently put a new crank in my 85, and if I run 10-40 oil the oil pressure wants to run bout 20 psi while cruising. Before the crank install I was running 20-50 royal purple it would stay around 40 on the highway at about 1600 rpms. Why does this motor want to run that kinda pressure at crusing? When i run the 10-40 weather its synthetic or not it wants to run low psi but with the 20-50 its higher and stays there. Oh right now its got 20-50 oil from autozone and even still it wants to stay about 25 psi while crusing. Just wanna make sure this is normal or if somethin could be wrong.
