I did some extension research a few years ago when I was looking for some and I did check the Penrite site but I didn't go with their recommendation for the Pas Fluid as it wasn't hydraulic fluid and it didn't meet MS-10838 specs. They do make a LDAS Hydraulic fluid for use in hydraulic power steering systems but again it doesn't meet the MS-10838 specs.
I was advised by a Jeep technician that ATF fluid or non-specific power steering fluid must not be used as a refill or top-up as seal leakage and/or pump damage will occur.
So I took no chances and went with the Mopar product.

Hmm for some reason I thought the WH was still on MS-5931 spec... but f%$k you're right, looks like MS-10838 has been spec'd everywhere.
I've found
one mention on Bob is The Oil Guy of "Pentosin® CHF 11S or CHF 202" being a replacement. But it's a bit vague.
Looks like I'll be flushing the PAS this weekend
... after a trip to the "local" dealer. Dammit.
I don't mind paying the dealer prices (especially when they're cheaper.), but the inconvenience sucks.
Thanks for correcting me! Hopefully no long term damage to the seals, no leaks so far.
