Thread: Correct PS Fluid?

K so I've asked this question multiple other places and nobody answers my post at all. Hundreds of views, no replies.. dunno why. All I want to know is... my PS fluid is low, getting a whine. The manual says to use the proper GM PS fluid, but can I use the Prestone Power Steering Fluid that Meets the service requirements of GM and blah blah blah?

I know it seems like a stupid question, but I've heard some people swear up and down to use ONLY the GM fluid directly from a dealer.

I just want to top off my reservoir and stop the whine, but nobody will answer me!
