it's been awhile but let me just recap my experience awhile back

just did a turkey baster drain/refill in the Dex III for my PS fluid in my BMW with Amsoil Univeral ATF ) - this is the older single formulation.
It was noisey and very made the steering very loose (which is complete opposite of BMW) in general. I then went to the local Autozone, figuring factory OEM was Castrol. I swapped this out and while it did lessen the noise a little bit, it was still there.

So off on a whim, I decided to use M1 Syn Dex III which did the trick. Was happy I found the right fluid and never looked back. As a matter of fact, I picked up 3 bottles when I read that their Universal ATF was switching up.


I plan to do a similar task now ...and was curious, what are the thicker/thickest viscosity Dex III on the market these days.
 
Most are at around 7.5-7.6 vis@ 100 deg C. Redline makes a high temp ATF that is a 10 @ 100 C? Seems like that would be one of the more viscous offerings while still flowing ok in colder weather. It also fully satisfies the Dexron III spec.

If you do not want to go that thick there is always the D4 which is superb in any P/S system calling for Dex II/III.
