Ford Australia specify Mobil 424 (or equivalent) tractor hydraulic fluid in their PS systems on Falcons.
It's a bit thicker, 9.7cst, and has a proper AW package, and just happens to be one of my new favourite lubes.
I've got about a half a system full of it in my Caprice, having jut replaced the power steering pump with a junkyard second after Mrs threw a few belts.
(Got a couple litres in the tranny too, just as an aside).
