Default High oil pressure

Afternoon all-
In my 07 burb, which I've had about 5 months now, I notice my oil pressure is running a little high after my most recent oil change. Not alarmingly high, but to the right of center. Comes back closer to center after it runs for a while but never really settles in the middle. Is this normal? I seem to recall it being in the middle before but don't recall for sure. Anyone?

I'm not sure how to post a pic- but at startup its almost over to 60 psi. I'd say 80% of the way from 40-60. After warming up I'd say its 33% of the way from 40-60.

Every now and then an impulse purchase comes in handy. I plugged in my Bluetooth obdii reader to get actual numbers. Warm engine idle is about 43-45 psi oil pressure. Revving up to 3k rpm gets me to about 57-58 psi. Holds steady.

Are you using the recommended 5w-30?
Correct filter?
How many miles are on the engine?
Has any rebuild work occurred?

No rebuild, 115k. 5w-30 max life. And a Napa gold filter. I really watched it today. Sits right at that 45 mark after it warms up. When I cruise out on the highway it gets closer to that 58 mark. I'm guessing this isn't normal?

Quite normal actually.....as ambient temperatures become colder going into the fall,observed oil pressures can go up.

Engine seems healthy for over 100K miles.

I agree that colder temps will cause a higher reading, but its also possible that the sensor is just off, you could always replace it for the sanity check...
