Oil pressure will be around 30-40 psi when at full operating temp.
That depends on what RPM you are asking about. Most every Pontiac I've ever had...in decent shape anyway, ran around 60 PSI at anything over 1500 RPM and would idle in the 30-40 range. Pontiacs were factory equipped with high pressure oil pumps and should run a higher oil pressure than a "comparable" Chevy.
normal oil pressure is 48 to 60
mine runs 40 psi
At idle, should run about 40PSI. Also depends on what size engine you have. At speed, like 55-60, no lower than 60-70PSI.
The oil gets thinner. It is normal for the oil pressure to drop after the engine has reached full operating temperature. If you have from 30-40 psi pressure when the engine is hot then that is normal.
The 2002 Pontiac Grand Prix SE has a normal operating temperature due to the engine. This is usually around 230 degrees.
I not sure what the normal temp is but I had a 94 grand am and it ran around 160 most of the time.

The normal oil pressure on a GM 305 engine is between 40 and 60 PSI depending on the model year. High oil pressure is needed to allow for proper circulation through the engine.
It is on the bottom of the engine block, just a normal hex bolt.
Dead Center at about 190 Degrees
Check with manual gauge - if pressure normal - could be defevtive oil pressure sensor or gauge
Need to know the year.
