Hydraulic oil is an important component of every hydraulic machine, allowing the transmission of power within hydraulic systems, which enables machines to move heavy loads with minimal effort. It also serves as a lubricant, coolant, and sealant within the hydraulic system.
However, hydraulic oil is susceptible to oxidation. Hydraulic oil oxidation happens when the oil undergoes a chemical reaction with oxygen, permanently changing its molecular structure and properties. This leads to increased viscosity, the formation of sludge and deposits, and corrosion. Unmitigated oxidation can decrease efficiency, increase maintenance costs and cause system failures.
To prevent such issues, this article will discuss the causes and effects of hydraulic oil oxidation and provide practical strategies to minimize its impact.
Hydraulic Oil Oxidation: Meaning and Causes
Hydraulic oil oxidation is a chemical reaction when oil reacts with oxygen, forming harmful byproducts. Oxidation is a reaction with several factors that can accelerate its occurrence, such as:
High Temperatures
High temperatures significantly increase the oxidation rate of hydraulic oil. Thus, it is crucial to maintain optimal operating temperatures to prevent rapid degradation and ensure system longevity.
Presence of Water
Water in hydraulic oil can significantly accelerate oxidation, as water molecules facilitate the reaction. This can lead to faster degradation and damage to system components. Thus, preventing water ingress and maintaining a dry system is essential to preserving the oil’s integrity and ensuring optimal performance.
Contamination
Contamination with particulate matter can significantly increase the oxidation rate of hydraulic oil, as these contaminants often act as catalysts for the oxidation reaction. This accelerated oxidation can lead to potential damage to the hydraulic system. Therefore, implementing effective filtration and maintaining a clean system is crucial to preserving oil quality and ensuring reliable operation.
Exposure to Oxygen
Exposure to oxygen is a fundamental cause of hydraulic oil oxidation, as this component is the catalyst for the oxidation process. Prolonged or excessive exposure can lead to rapid oil degradation and reduced system efficiency.

What Happens to Oxidized Hydraulic Oil
Oxidized hydraulic oil can cause various issues affecting machinery performance. The primary negative impact is reduced lubrication properties, which leads to increased friction and wear on moving parts.
This increased wear can cause premature component failure, resulting in costly repairs, extended downtime, and even system failure.
Moreover, oxidized hydraulic oil can also lead to the following:
- Reduced Machinery Efficiency: Oxidized oil can lead to increased friction, reduced lubrication, and decreased hydraulic system performance.
- Corrosion: Oxidation byproducts can corrode metal components, leading to premature wear and system failure.
- Increased Wear: Oxidized oil can cause excessive wear on moving parts, increasing maintenance costs and downtime.
- System Failure: In extreme cases, oxidized oil can lead to complete system failure, resulting in significant losses and downtime.
Additionally, oxidized oil can lead to increased viscosity, which restricts oil flow and causes clogging of filters, strainers, and valves. This can further exacerbate the issues by reducing the system’s overall efficiency.
