Hey Paul, The hydraulic shop was very adamant about changing the fluid, but I forget why. Maybe the 10 weight has a higher viscosity than power steering fluid? The Navtec owner's manual states the same fluid. I'll send it to you in a separate email. My system has a single -10 Navtec cylinder, a remote hand pump, and reservoir and one guart was more than enough to fill the system, so it was an easy change, IIRC. Chuck
