Hydraulic oil is a non-compressibility fluid used in hydraulic systems to transmit power. It is designed to perform several functions, including lubrication, cooling, cleaning, and sealing. The specific properties of hydraulic oil are critical for the efficient and reliable operation of hydraulic machinery.

These fluids are typically mineral oil-based, but synthetic and vegetable-based hydraulic oils are also available for specialized applications or environmental considerations. Key properties include viscosity, which must remain stable over a range of temperatures to ensure consistent performance. Viscosity index improvers are often added to achieve this. Other important characteristics are oxidation stability, which prevents degradation of the oil over time, and anti-wear additives that protect the moving parts of the hydraulic system from friction and damage.

Hydraulic oils are used in a vast array of equipment, from construction machinery and industrial presses to aircraft controls and power steering systems. The selection of the correct hydraulic oil depends on factors such as operating pressure, temperature, environmental conditions, and the specific requirements of the hydraulic components. Regular maintenance and replacement of hydraulic oil are essential to prevent system failures and extend the lifespan of the equipment.
