What should my oil pressure run in my low miles 2011 g.s ? At idle its around 50, and on acceleration it goes into the 70's. Oil temp on short runs to the gym (2 miles) is in the 130's, ambient temp is in 70's. This just seemed high when i noticed it today. If this is too high, what could be the problem ? Thx, i appreciate your feedback.

Mines 50 at cold startup, 30 warm idle, and 40 at 1200 rpm. Oil temps run about 200 give or take. On my 3rd Vette, seems about normal.

depends on if you have a coupe or not. the dry sump system will run considerably higher oil pressure than the wet sumps. if you are running a dry sump your pressures seem just fine.

Mine runs 80 psi cold at idle. I try not to rev it up until it warms up. Oil temp stay 50 degrees lower than water temp. GS dry sump.
Yours seems just fine.
Rule of thumb on all engines. You need 10 psi for every 1000 RPM. That is a warm engine, ready to run hard.

yes, mine is a dry sump coupe, so i guess it sounds about right...

Cold at idle mine is about 50 psi and goes to about 65-70 with a few revs. Warm at idle its about 40 psi and goes up to 55 or so with a few rev. These oil pressure sensors vary. On my C5 the warm idle pressure was under 30. After changing the sensor it was about just under 40.

Don't worry about. If you hear your engine start to clank or make clattering sounds then worry.
