As we have discussed in the previous blog, hydraulic oil pretty much works like the blood for any hydraulic system. Take the hydraulic version of the Tata Hitachi wheel loader in Jharkhand, it wouldn’t be able to function without hydraulic oil.
Not only does it transfer energy within the hydraulic system, but it also has a variety of other functionality. In this blog, we will be covering 2 important aspects. We will talk about the incompressibility of hydraulic oil. But more importantly, we will be looking at the various uses of this oil. Let’s begin.
The incompressibility of Hydraulic Oil
Just as viscosity is a very important property of hydraulic oil, Incompressibility is equally important. It is key to the functioning of hydraulic fluid. Technically speaking, the capacity of an element to be flattened or reduced in size under changes in pressure is called its compressibility.
Therefore, if we talk in the context of hydraulic oil, it is incompressible in nature. In other words, even under very high pressure, it doesn’t change its volume. But why is it in such a big deal? Because it increases the efficiency of the machine. The output is much effort when compared to other heavy machinery oils. It also reduces machine fatigue and cavitations. Remember this point next time you have second thoughts about going for hydraulic machinery.
Uses of Hydraulic Oil
After covering the various aspects of hydraulic oil, let’s talk about the main point- its usability. Hydraulic fluids are widely used for various types of applications. We have listed below 10 of its applications to give you an idea.
-
This oil makes excellent brake oil for automobiles. A good brake oil ensures that the car comes to a smooth stop. Therefore, it is essential for the safety of a car. Glycol ether or refined mineral oils form the perfect base for this utility.

According to Tata Hitachi dealers, bulldozers, excavators, cranes, lifts, uses a hydraulic system. Under high pressure and heavy load condition, this oil proves to be the best choice due to its high viscosity and anti-wear additives. Its anti-freeze additives make them perfect for snow-plow.

As aviation covers a wide range of temperatures and conditions, hydraulic oil is a huge application. The aviation industry uses in flight control, landing gears, wing movements, brakes, etc. A high viscosity index and incompressibility really come in handy.

Hydraulic oils such as water-glycol or phosphate ester synthetics are most suitable for operations that produce excessive heat. Military and metal industry uses it for die casting machines and furnace hydraulic systems.
