I doubt that the Mobil 1 has much to do with the low oil pressure.
10W-30 is 10W-30, dino or syn. Are you sure of the pressure gauge?
Might be a good idea to put a direct acting gauge on it and see what it
says. I have a Dodge 360 that only showed 30 psi on the dash gauge afer
I rebuilt it. A direct gauge showed 80 psi.
