Honda PS fluid is normal stuff, if you have a Honda.
Back 15 or so years ago, Chrysler started using ATF for PS fluid. Last fall they discontinued the "old style" PS fluid, superceding that part number to the ATF. Except we know it's not a good supercedence because they didn't do it 15 years ago. And I think I have two kinds of PS fluid for electric systems. And they're all "normal."
