Hydraulic Oil: What It Is, What It Does, and Where Is It Needed

Most vehicles have several fluids that are required to complete the different functions that the vehicle requires to work properly. We have often discussed the importance of motor oil and its function as a valuable lubricant that protects the engine. However, there are other important fluids that also play an important role in helping your engine, and the vehicle as a whole, to properly function. Today, we want to focus on hydraulic oil and what it does.

What Is Hydraulic Oil and Why All Hydraulic Systems Need It

Hydraulic oil also known as hydraulic fuel can be considered a lubricant, but it is in fact much more than that. What makes hydraulic oil unique, is its ability to efficiently transfer power from one point to another. Its dual function is crucial to properly conduct power throughout the hydraulic systems. A hydraulic system is basically a system that works by transferring  the force that is activated at one point to another point. It does this with the help of a fluid that is not compressible. That fluid is the hydraulic oil.

3 Common Types of Hydraulic Fluids That Your Vehicle Requires

  1. Brake Fluid. One of the systems that require a type of hydraulic fluid is the brake system. The brake system is a hydraulic system that requires brake fluid, a form of hydraulic oil, in order to work. Brake fluid is created to withstand higher levels of heat because intensified heat can cause it to become compressible. It is absolutely necessary that a hydraulic system (such as the brake system,) is able to rely on an incompressible fluid. If brake fluid is confronted with a tremendously elevated temperature it can begin to turn into gas and become compressible, which can lead to the brakes failing. That is why it is so crucial that your vehicle relies on a highly resistant brake fluid to maintain your brake system functioning at its best. AMSOIL offers truly resistant lubricants and other quality products that your vehicle needs. Contact Mooresville Synthetic Oil today and start using the most durable brake fluid and other hydraulic oils that not only serve their function but that can also enhance the performance of your vehicle.
  2. Clutch fluid. Clutch fluid can also be considered hydraulic oil. It is the fluid needed to change gears and is more commonly referred to as transmission fluid. In many cases, the transmission fluid can actually be brake fluid itself but it does have its own hydraulic cylinder. It is necessary that you verify with your manufacturer what kind of fluid it contains and needs. In most cases, you should not have to add more fluid but if there is a leak or any other problem begins to present itself then it might be necessary and it is good to know what kind it requires and whether brake fluid will really do the job.
  3. Power-steering fluid. Another important kind of hydraulic fluid that works to assist your vehicle is the power steer fluid.  As you already know, the power steering system is responsible for being able to steer your vehicle with ease and efficiency. This system also relys on a hydraulic oil commonly known as power steering fluid which can many times be a mineral based oil.

Other Properties of Hydraulic Oil

As we already mentioned the hydraulic oil has lubrication properties. It also contains other properties that most lubricants contain. Such as wear protection, anti-oxidation properties, and temperature stability. Its main function, however, remains in power conduction. Among its secondary functions is contamination containment. Hydraulic fluid protects the hydraulic system from contamination and helps avoid filth from damaging it. It is assisted by a filter that contains all the trapped contaminants.

Heat and Hydraulic Fluid

Heat can be quickly transferred through fluids and because of this, it is perfect for conducting of thermal energy. When there is hydraulic energy being generated but not used in the hydraulic system for imperative functions the result is heat. When the heat intensifies and very high temperatures are reached it becomes necessary for it to cool by being carried away from the components. Depending on the quality of the hydraulic fluid it may be able to withstand more intensified temperatures. To read more about hydraulic power and the common problems and solutions, click here.
