Seems I read somewhere a while back that you could replace your power steering fluid with synthetic ATF to help reduce parasitic drag boosting power/mpg/etc.

Anyone done this or heard of doing it? Thought I'd ask before I try, I don't want to find out later that it's a no-no. I have 3 qts of Redline Syn ATF dextron II/III laying around, thought I could put it to use.

Thanks in advance.
