I've been a member of this board for awhile.
Larry Bible has replied to many of these power steering fluid posts.
I know that in many, he has mentioned going to your local McParts and buying plain ole power steering fluid. Nothing fancy, nothing expensive, just plain ole power steering fluid.
If Larry has been doing this for years, then I'd say plain ole off the shelf power steering fluid would be ok.
My 2 cents.
