Hydraulic fluid additives are widely used in passenger and commercial vehicles as well as in special vehicles. These products are intended for the protection of hydraulic systems from premature wear, help to increase their working performance and prevent leaks. In passenger cars and commercial vehicles, they are most commonly used in power steering systems. They have a wider area of application in special vehicles.

What are the types of hydraulic fluid additives:

By operating principle:

  • Anti-wear. They protect the system components from abrasive wear and ensure a smoother travel of contacting elements. These additives prevent fluid foaming and corrosion of metals.
  • Detergent. These dissolve deposits on system parts and prevent new ones from forming. Such additives keep dirt particles suspended. They have a positive effect on the performance of the unit, extend its lifespan.
  • Restoring. These products form a durable cermet film on worn out components, thus restoring their original size and shape. They ensure quiet operation of the system, eliminate vibrations and reduce the force needed to turn the steering wheel.
  • Seal swell. They will increase the elasticity of rubber and plastic elements and restore their sizes. This eliminates gaps, thus preventing leaks.
  • Viscosity modifiers. Such additives help to maintain the oil viscosity at extremely high temperatures and are mainly used in special vehicles. They help to improve the performance of hydraulic machinery.

It is quite common for one product to perform several functions.

Features of using hydraulic fluid additives

  1. Study the instructions and follow the manufacturer’s recommendations. Some agents have to be added to the used hydraulic fluid while others are poured into the new one. Some products are to be applied in two stages. At first, they are added to the used oil which is drained after some kilometres travelled, and then they are added to the fresh one.
  2. Use the additives in the proportions recommended by the manufacturer. The concentration of the substance can vary depending on whether the vehicle is passenger or commercial.
  3. Before using the products, you should make sure that they are compatible with the fluid to which they are going to be added.
  4. Avoid using different additives at the same time in order to preserve their effectiveness.
  5. Some products have to be used regularly. This will help to prevent many failures and extend the service life of the hydraulic system by 1.5 - 2 times.
