Jim,
For what it is worth, Toyota's factory fill fluid for the power steering system IS NOT red. With that in mind, what do you think they use?

Dan, could it be a proprietary PS fluid that toyota had made for them? One thing I noticed is in my '01 honda FSM, it states intervals for changing the fluids, and specs a long initial interval, then shorter intervals after that, as if a lower quality fluid was assumed to be used. For example, it says the change the coolant at 60K mi or 5 yrs, then at 30K mi intervals afterwards. Similar goes for the manual tranny fluid, ATTS fluid, etc. Any validity to this theory? Motors oils in Japan have a different rating (not SJ/SL like here). My bro-in-law's toyota has stickers in the engine compartment that specifically say to use 10w30, not 5w30 like w/ N.A. toyotas, and 'long-life' coolant. I know on some guys 4runners, it says to use ATF w/ Dextron II for the PS. Makes me wonder if the PS fluid toyota uses (in Japan or even in N.A.) is more like ATF in quality/performance than the common PS fluids available off the shelf?
