Replacing the power-steering fluid is not usually listed as a maintenance item for most cars and trucks. You may have read that it’s a good idea or heard a mechanic give you a pitch for it, though. The question is: Should you do it?
Well, it’s a matter of interpretation to some degree. The truth be told, power steering fluid does age. When it is new, it is usually a clear-ruby color similar to many cough syrups. As time goes on, usually many years, the ruby color turns darker as small amounts of dirt and other contaminants become suspended in the fluid. To many mechanics this indicates that the fluid is old and should be changed.
