After car is warmed up. Oil psi is a little below 20 at idle.

I use oem filters with castrol full sythetic.

Before I use to use Amsoil with Amsoil filter. Got a little too pricy for me.

But oil psi was same wig Amsoil as well.

 

I have posted factory oil pressure specs a dozen times. Worth a look.

 

15-20psi at idle is normal.
