Using ATF+4 (Redline C+) as powersteering fluid

[Chuck1986]

The owner's manual for my 2001 Mitsubishi Eclipse GT calls for Dexron III ATF to be used at powersteering fluid. However, I have a couple quarts of Redline C+ ATF laying around that I'd like to use instead. This is a very high quality sythetic transmission fluid (meets ATF+4, SPII/SPIII specs) and I was wondering if I could use it as my powersteering fluid? Anyone know if this could be harder on the powersteering pump?

My guess (only a guess) is that it is a much better fluid than required and would work fine.
