I want to flush my mercury's power steering fluid. I was told ford fluid is best

What is your question?

My fluid looks a little muddy and far from red. Seeing that it's not a hard job draining the return line while turning stop to stop, then refill. Turn wheel stop to stop then refill. Check after short test ride to rid the system of any air. But is it true fords fluid is best and is it synthetic or regular type F. Thanks for the help as the car is worth it, runs great and gives me no grief. Thanks guys for your time to respond. The Falcon !!!
