Once drained, replace the plug, fill the reservoir with the new fluid through the filler plug, and pump the jack several times to purge air bubbles from the system. For floor jacks used in garages that experience temperature swings, a 10W-30 or 15W-40 is often the ideal balance.

This guide breaks down the science behind hydraulic fluids, the specific requirements for different jack models, and the step-by-step process for changing your fluid. These fluids contain additives and detergents designed for engines, not hydraulic pumps, and can cause foaming or seal degradation over time.
Too thin, and the jack will leak and lose pressure; too thick, and the pump will become stiff and difficult to operate, especially in cold environments. If your jack is stored in a cool workshop, a lighter 5W-20 might ensure easier priming, while hotter environments might require a 30-weight to prevent thinning.
