I have looked through my instruction manuals but I have not found details on filling the hydraulic fluid for my suspension. I check the resevior and found that it was barely at the tip of the bottom of the dip stick. I wanted to know what is the procedure for filling it. Do I do it with the engine running or off? The manual did say that it holds 2 quarts but do I have to have the engine running to pump the fluid to the rear and give me the correct level on the dip stick. What other brands of fluid are compatible?

Thank You
