PA Oil Pressure

What should my oil pressure read at idle? Mine is really low and kinda scares me, I am an old motor head that is used to 40 pounds at idle so maybe I am just panicking a little too much.

The stock gauge is unreliable, so it may not be showing the correct reading.

30-40 PSI is normal.

mine is just below the first mark at idle and just below the 2nd mark at cruising speed. it goes about half way up when you rev it up

check if the sensor or gauge is faulty before anything.

This oil pressure variation is common, particularly with 20W50 oil and cooler weather. Can't help with the exhaust.

I've had the oil pressure sensor replaced twice in my FD. It seems like it lasts for a few years and then gets intermittently flaky. It would sometimes drop to zero for a while and then start working again.

When it first happened, it was making me really nervous. I took it to a Mazda dealer near Lansdale PA. They couldn't figure it out and told me to just not worry about it. I just took it to a local shop that replaced the sensor and that fixed it (until the sensor wore out again a few years later). It also took me a few times of trying to use the Mazda dealer in Lansdale before I realized that they were not up to the task of working on an RX-7.
