Everything You Need to Know About PAO Fluids in the Aviation Industry

Polyalphaolefin (PAO) fluids are synthetic lubricants widely used in the aviation industry due to their excellent performance in a wide range of operating conditions. PAO fluids are made from hydrocarbon-based molecules with uniform molecular structure, which leads to their outstanding lubrication properties.

PAO fluids have many advantages over mineral oils, such as better low-temperature performance, lower volatility, and better thermal stability. These benefits make PAO fluids ideal for use in various aviation applications, including aircraft engines, hydraulic systems, and landing gear.

One of the main advantages of PAO fluids is their excellent low-temperature performance. They remain fluid at very low temperatures, making them ideal for use in cold environments. In addition, they have a low pour point, which means they will not thicken or solidify in cold temperatures. This makes them suitable for use in areas such as the Arctic, where temperatures can fall to extremely low levels.

PAO fluids also have a lower volatility than mineral oils, which means they evaporate less and maintain their viscosity and lubrication properties for a longer time. This makes them ideal for use in high-temperature environments such as aircraft engines and hydraulic systems.

Another advantage of PAO fluids is their excellent thermal stability. They are resistant to oxidation and thermal degradation, which means they can maintain their properties and lubricating performance in high-temperature environments. This makes them ideal for use in aircraft landing gear, which is subjected to high temperatures during landing and takeoff.

PAO fluids are also less likely to react with metals and other materials, which can lead to corrosion and damage to equipment. They have a higher flash point than mineral oils, which means they are less likely to ignite in high-temperature environments.

In conclusion, PAO fluids are an excellent choice for use in the aviation industry due to their excellent low-temperature performance, lower volatility, better thermal stability, and resistance to corrosion. They are widely used in aircraft engines, hydraulic systems, and landing gear, and are an essential component of modern aviation maintenance and repair operations.


Summary: PAO fluids are synthetic lubricants widely used in the aviation industry due to their excellent performance in a wide range of operating conditions. They have many advantages over mineral oils, such as better low-temperature performance, lower volatility, and better thermal stability, making them ideal for use in aircraft engines, hydraulic systems, and landing gear. PAO fluids are an essential component of modern aviation maintenance and repair operations.
