GM Power Steering Fluid Specification?

[paulo57509]

Does anyone know what current specification (if any) does GM P/N 1052884 PSF meet?

The owner's manual for my '03 GMC calls for this P/N "or equivalent".

I'm not hung up on using generic PSF, but I have a few quarts of Pyrol PSF that lists a GM spec on the label and it would be nice to know if the Pyrol is equivalent.

Thanks.

Searching the internet and other forums, there seems to be some confusion on whether the specification is 9985010 or 9985835.

I'm unaware of the spec and my manual doesn't list a spec, only part numbers. I used this item and purchased it at my local GM parts place for around $9 / quart.

"This fluid also satisfies power steering units requiring GM PN 1050017 or 1052884 (Spec Number 9985010)"

This is what is on the Redline PSF bottle. At least one of those part #'s and the spec. # is also in my '96 Buick Roadmaster owners manual. The 2 part #'s might be different size bottles, I'm not certain however.
