Hydraulic oil is an incompressible fluid that transmits power within hydraulic equipment and machinery. It is available as synthetic or mineral based. It also acts as a coolant, sealant and lubricant. Therefore, it is largely used in hydraulic machinery to reduce friction between different parts and extend the life of the machine.
What is Hydraulic Oil Analysis?
Hydraulic fluid analysis is a crucial step that a hydraulic fluid supplier must take before supplying it to another company for use. A sample should be sent to the lab to find out if the oil is good or needs to be changed. This process will provide assurance on the sustainability and longevity of their equipment if users use this oil. Because if the oil is not of good quality, it can damage the user's expensive machinery.
High quality hydraulic oil ensures:
- It will minimize the wear and tear of your machine.
- Hydraulic fluid will reduce the possibility of any damage to the product or machine.
- It will reduce the possibility and risk of injury, as well as the cost of related claims and damages.
Hydraulic Oil Properties and Functions
Hydraulic oil has excellent qualities such as chemical stability, purity and correct composition. Therefore, it is highly demanded in the market.
The main function of hydraulic oil is to transmit power. However, it has many more functions such as the protection of hydraulic machine parts.

What are the Uses of Hydraulic Oil?
Hydraulic oil is mainly used to transfer power. The areas where it is used are as follows:
Automotive Lifts
Hydraulic fluid is required to power car lifts or jacks. Machinery used for automotive lifts mainly relies on quality hydraulic fluid for better performance and safety. In this type of automotive lifts, the viscosity grade is high due to the higher pressure.
Marine and Passenger Ships
Hydraulic oil is used for stabilizers in watercraft and mainly on a cruise ship. This helps reduce the number of rolls that can affect cruise stability and cause seasickness. Hydraulic oil is also required for a number of other applications in watercraft.
Planes
Aviation control systems use hydraulic fluid. Therefore, the oil must be extremely reliable. It is also used in aircraft jacks, aircraft hangar doors and aircraft controls.
Aircraft
It is achieved by means of high pressure hydraulic fluid for air tools and compressors. Therefore, it has an anti-wear additive feature for safety and protection.
Log Separator
The cutting mechanism of a log splitter needs more power than the equipment can split the log easily. This power is obtained thanks to the hydraulic fluid.
Tractors
Hydraulic oil is essential for operating hydraulic brakes and hydraulic systems used in agricultural machinery and vehicles. When using hydraulic fluid for an expensive agricultural machine and vehicle, such as a tractor, it is essential that you purchase it from a well-known hydraulic oil supplier.
Snow Plows
A snowplow blade can be used for tilting, lifting, etc. Hydraulic fluid must be used for strong different angle movements. Thanks to the anti-freezing additives, the oil is prevented from becoming useless by freezing.
