what is good oil pressure for 93 safari?

[dale rex]

Just bought my first safari. It is a 93 slt with 95,000 miles.It is in just about perfect condition. Really taken care of by previous owner. One point of concern is oil pressure reading on digi guage. It reads about 20 psi at idle and climbs consistently with acceleration to about 40 or 50 psi.Is this normal? or should the pressure be the same at all speeds? just curious whether this is a sign of something bad or just normal for this engine. Thanks for any response.

I have a '92 with 130K and it does the same thing, runs great. I'd say no problem.
