When I bought my 300D the power steering fluid looks redish and I always wonder why. May be it was ATF in there. I topped it up with normal power steering fluid, actually I top up all my project cars with normal run of the mill stuff p/s fluid and I do not have any issues.

I presume it would not do any harm by mixing it?? Any info would be appreciated.
