Spec is for 13+ at idle and 37-75 when running. 5w30 isn't the cause. Verify with a mechanical gauge or replace the sending unit if its obviously leaking oil or weeping oil into the plug.

think ima do that it could be my gauge cluster as it has problems with the ground every now and then the spedo just turns off and airbag light goes on maybe its not showing the oil pressure correctly as well.
