Clean lubricating oil: the key to optimal performance
Optimal performance and a long service life for machines are crucial to a company's productivity and competitiveness. One of the most important factors in achieving this is keeping the lubricating oil clean. Maintaining oil cleanliness is a critical necessity for ensuring efficient operation, minimising downtime and reducing the cost of repairs and replacements. A consistent focus on oil quality is therefore not just good practice, but an essential part of effective machine maintenance.
The invisible enemies of your oil
Oil contamination is one of the main causes of machine failure and reduced performance. To tackle this problem effectively, it is important to understand the different types of contamination and where they come from.
Contamination can take many forms. Here we take a closer look at some of the most common sources.
Particles: this includes dust, metal shavings and other solids that can cause wear on machine components.
Water: even small amounts of water can lead to corrosion and degradation of the oil.
Air bubbles: can cause cavitation and reduce the lubricity of the oil.
Chemical contaminants: include fuel, coolant and other chemicals that can change the properties of the oil.
Where does contamination come from?
Contamination can come from many sources, and identifying them is essential to keeping the oil clean. Look out for signs of contamination from:
External ingress: through leaking seals, breathers or during filling.
Internal generation: wear on components, chemical reactions or oxidation of the oil.
Maintenance-related contamination: inadequate cleaning during oil changes or the use of contaminated equipment.
Strategies for clean lubricating oil
There are some overall strategies you can follow to keep your oil as clean as possible.
Focus on filtration
A robust filtration system is essential for removing particles and other contaminants from the oil. Choose filters with the right pore size and capacity for your specific application.
Use both suction filters and pressure filters for optimal protection.
Consider introducing bypass filtration for continuous cleaning of the oil.
Replacing filters regularly is essential to maintaining their effectiveness.
The hidden threats of water
Water in the oil can have serious consequences for the performance and service life of your machine.
Install effective seals and gaskets to prevent water ingress.
Consider installing a water separation system, especially in environments with high humidity.
Regularly checking the water content of the oil can help detect problems early.
From drum to tank
Correct storage and handling of oil is essential to prevent contamination before the oil even reaches the machine.
Store oil drums indoors and away from direct sunlight and heat sources.
Use clean pumps and hoses when transferring oil.
Introduce a "first in, first out" system to make sure older oil is used first.
The oil health check
Oil analysis is a powerful tool for monitoring the condition of the oil and the health of the machine.
Set up a programme of regular oil analysis.
Analyse for particle count, water content, viscosity and other relevant parameters.
Use the results to adjust maintenance intervals and identify potential problems early.

Knowledge and training are a good investment
Well-informed and well-trained colleagues are the key to maintaining clean oil systems. It is therefore a good investment to train your colleagues in correct procedures for oil handling and filling.
Teach them the importance of reporting abnormal conditions or suspected contamination.
Keep everyone up to date on the latest best practices in oil care.
Advanced oil care
For companies that want to take their oil care to the next level, there are several advanced techniques:
1. Electrostatic oil cleaning
This technology uses an electric field to remove even microscopic particles and water molecules from the oil. It is particularly effective at removing contaminants that conventional filters cannot capture.
2. Vacuum dehydration
A process that effectively removes dissolved water and gases from the oil. This is especially useful in hydraulic systems and transformers, where even small amounts of water can be harmful.
Real-time monitoring
Introducing real-time monitoring of oil condition can provide instant insight into the health of the oil and the performance of the machine. This enables proactive maintenance and can prevent unexpected breakdowns.
The benefits of clean lubricating oil
Keeping your oil clean not only has technical advantages, but also significant financial and environmental benefits.
Clean lubricating oil reduces operating costs, extends the service life of the machine and reduces the need for repairs and replacements. Energy efficiency increases, because machines running on clean oil operate more efficiently and use less energy. And finally, extending the life of the oil reduces the need for disposal and for production of new oil, which lowers the overall environmental footprint.
Future-proof oil care
Keeping oil clean is a continuous process that requires attention and commitment. By implementing the right strategies and techniques, companies can achieve significant benefits in the form of improved machine performance, reduced costs and greater operational reliability.
By following these guidelines and continuously evaluating and improving your oil care practices, you can make sure your machines and equipment always perform at their best. Ultimately, it is about creating a culture of proactive maintenance and oil care that runs through the entire organisation.
