whats the normal oil pressure on a 1993 wrx?

on tick over.
I get over 85 on start up.
bout 20 minutes running it drops to 60 on tick over when at junctions.
on longer runs It will drop right down to 40-

when driving in all these conditions it will rise back to 80.

so my question : is this normal, and is it due to oil temp or is there something wrong.

Dunno wot normal is but with Pro R 15w50 oil I get 6 to 7 bar cold/winter cold on first start up
Then drops to around 3 bar at tickover when warm/hot.
If driven hard may drop slightly lower on tickover but not loads.
So, yours look normal to me. Same roughly as mine.
Dont forget of course the oil viscosity will make all the difference! 15w50, etc I mean.
