How many miles on the oil? If you've got over 10K, it's probably normal. I average around 27-28 when the oil is hot at idle (in gear--about 500 RPM) and 40-50 above 1000 rpm.
Either way, you're still well within GM specs.

My 98 manual states:
"Oil pressure should be between 20 to 80 psi. It could read as low as 6 psi and still be considered normal at long, extended idles."
I think you're okay. :yesnod:

Your oil pressure is JUST FINE. Don't sweat it. My 01 Coupe didn't get readings that high - 15 or so at idle and 30-35 with the original factory fill of 5-30 and went to about the same as your readings after the first change/fill with 10w-30 and a UPF filter. PLUS your readings are WELL within spec. 'Normal' oil pressure readings seems to be all over the map and depend on many variables BUT, as 98 BlackMagic said:
"Oil pressure should be between 20 to 80 psi. It could read as low as 6 psi and still be considered normal at long, extended idles."
Again: don't sweat it. Believe what the FACTORY says; they built it (the engine) and THEY know what is normal.
