Yep it has been discussed since time immortal. The manufacture says use A and people use B. Having just had a steering leak, i started wondering about this again.
So toyota (my case) specifes dexron ii for the power steering system fluid. however, over time, the components of the system change: hoses get replaced, power steering pump gets replaced, etc, etc. I suppose if you only use toyota parts dexron ii will be the fluid, but if you don't and use things from napa/autozone/etc do those replacement seals/rings/etc really really need dexron ii versus PSF? (or vice versa depending on your vehicle)
Personally i always used mobil 1 atf or amsoil atf in my system figuring it was a higher quality fluid. but really, i don't know the difference between true psf and a synthetic dexron atf.
your thoughts?
