Honda PSF in a GM PS unit

[The_Eric]

I thought I'd post this up for another member...

Back story: Some time ago I posted in someone else's thread about topping off the reservoir in my wife's Malibu using Honda PSF (all I had at the time). I had remarked that it was a bit noisy on cold winter mornings and that after I did that, it stopped. If I remember correctly, Vikas or Hokyfied??? Maybe one of those two I think seemed interested and wanted future results.

Well here they are- was changing her oil the other day and decided to change out the rest of the PSF with some OE Honda PSF that I bought a while back. Suctioned out as much as I could and refilled with the Honda stuff and ran the engine/cycled the wheel several times. Used about 2 quarts in all. The result? I went out and started the car one -10*F morning and silence! I don't know what's so special about the Honda lube, but it made a believer out of me.

I've tried various PSFs on her GM pumps throughout the years (her Grand Am, then the Malibu) and they have always groaned/whined when colder than about 10*F. So this is a success to me- just passing on some anecdotal info to anyone who is interested.

A VOA might indicate banana puree.

All my GM power steering units have always been quiet as long as whatever was in there was not mixed. I had good results with Prestone PSF then it started making noise when I tried converting to royal purple psf, then when I went to dex/merc+Maxlife atf it got quiet again, I like the Maxlife the best it makes it easy to steer on cold startup due to the lower viscosity

Royal Purple fixed my noisy GM PS units

Honda PSF may not work well in other GM power steering systems but it works good in yours so keep using it.

One thing I am pretty sure is only PSF approved for Honda is usable in Honda power steering systems.

Best thing I have found for GM pumps so far has been MaxLife. My Roadmaster shrieked so bad at times, I was ready to replace the pump. Did a complete fluid exchange for Maxlife and have heard nothing since.

redline ATF solved my noise issues in my Saturn outlook

I have bought numerous store brand power steering fluids that say "For Honda" and the label says it is okay for use in cars that take regular PSF.

Amsoil multi-vehicle ATF has been working well in my Toyota and Ford PS systems, but still use Honda PSF in the Honda.
