Type F or is there a better PS fluid?

[MaD]

Putting in a new power steering pump and used steering box. The previous one whined loud as hell so I'm hoping this one is quieter. Should I use type F as suggested or is there a better fluid?

Use what the book calls for, be sure to turn it lock to lock several times to get the air bled out of the system.

i have heard that putting some friction modifier in with the fluid helps quiet them down some, not sure how true that is or not
