Powere Steering Fluid

What type of power steering fluid do you guys put in ur cars?
I heard that the fluid that u buy in the stores or auto shops have additives that waste the o rings, and that its better to buy it from the dealer.
Any recomendations?

i used valvoline....just make sure you dont' over fill it and under fill it...you will screw up your rack.

haha, that sounds like dealer BS if you ask me. i bet if you compared a store bought power steering fluid w/ the nissan fluid, the only difference is in the labels.
i hate goin to the dealership for anything, cuz they overcharge like crazy.

ok then i guess i'll just use any, thanx
