My Power assisted Steering (PAS) fluid has been on the minimum line since I got the car. There are no leaks as I fully inspected the car when I recently did an oil change. I am thinking of topping it off. However, I cant find the recommended fluid here in the US which is Fuchs Titan ATF Dexron II. What do you guys recommend? I searched Amazon and most I see are Dexron IV fluids. OR should I just leave it alone?
