Normal oil pressure?

Sorry if this is a Dupe but I did try the search function first.....

What is "normal" oil pressure?

I think that the minimum is 6-8 psi at idle and 18 @ 2000 rpm.

I'm way above those numbers 22 @ idle and 27 @ 2000 rpm.

Just a little worried since the pressure used to be 32-33 psi @ 2000 rpm.
I'm using Mobil-1 5-30. At 30,000 miles is it time to switch to 10-40 weight oil?

I run Castrol 0w30 (which is almost a 0w40) and I see 28-29psi at idle and 42-44psi at 70mph (with a 200F oil temp) At WOT I see around 50-52psi.

My oil pressure is 30 psi at idle. Something is definately wrong if your oil pressure is dropping when you accelerate. If I were you I would not drive your car until you can find out what is wrong.
