not easy to change it completely but you can empty reservoir and refill it , if you do it several times the more you change,if you do it once a year or so it keeps systems oil fresh

Also I've seen these additives that supposedly seal leaks in the system, I've a very slight leak coming from the steering box, so I may be an opportunity to use that when I refill
