Condensate in the oil.... Only driven five miles and never run long enough to eliminate condensate... Short runs every month are worse than not starting the engine, either run it for 30+ minutes to build heat in the engine or don't start it...
I have never seen condensation change the color like that but that is what my old man said. If it passes the pressure test then I’m going to let it run for 30 minutes in the garage then check the oil again.
