Just had the oil changed and my psi is at 51 on the gauge and on Insite while idling.It’s usually at 40 or a little under while driving.04’ cm870
maybe start by replacing/verifying the oil pressure sensor?.

Oil psi gauge acting strange with truck off and key on.You can also see when I turn it on it it moves up to 80 and then back down.
