Power Steering fluid works hard and should be changed occasionally! (every year)
I use a veterinary syringe with rubber hose to suction out old fluid.
You want to hear your pump quieten down & run cooler smoother, add this into pump!
Protects seals no stiff steering when cold either! ( I buy 32 oz bottle good for 3 refills)

I run full synthetic motor oils as well in the Park Ave. I remember how after a fresh oil change w/ filter I could clearly hear some valve clicking going on.
I added this and withing 1 minute the engine'* valve friction was removed and went completely quiet. Now I use it at every oil change. Just got 35.4 mpg in the mountains with a car that should get 25-28 mpg on highway. Oil stays way cooler too!
