This is a very general question. I am familiar with hydraulic or "bottle" jacks, and I think this is what your question is about. Hydraulic jacks have a pump to force hydraulic fluid into a hydraulic cylinder, which forces it to extend. This action is what raises whatever load you place it under. The fluid is usually pretty specific to the jack. Go to your local hardware store and ask for hydraulic jack oil. I have seen people use transmission fluid in a pinch (way out on the farm, miles from the store).
