I did 5-6 suck and fills using a turkey baster in my Saturn after nearly 100k miles on the original fluid. Used SuperTech Power Steering Fluid to complete the change. I ran about 1.25 qt through the system and now the fluid is an amber color.
I only wish I discovered the "line" leading to the pump several months ago so I wouldn't have had to resort to the turkey baster method. I think when I do the oil change next week or so, I'll drain the entire system through the line (and turn the steering wheel from side to side) to remove all of the old fluid.
