When I take my car to local tire and car repair shop to have the oil changed, they always check my power steering fluid and come back with a "sample" of it in a special device that sucks up my fluid in one side and compares it to CLEAN power steering fluid in another side.
I always tell them NOT to check any other fluids and to only do the oil change but they present me with this "finding" every time.... and show me how DIRTY my power steering fluid is and asking if I want to change it out.
Question: Is this a legit concern? Dirty power steering fluid and should I have it changed?
Or is this some kind of scam?
Car is a 2000 Mazda Protege with 200k miles on it and I am original owner.
