Manufacturing plants around the world struggle while they plan to bulk-buy their lubricants for industrial-scale machines and their hydraulic systems. Their trouble increases when they get to the market and realize there are hundreds of options available. While each brand claims that their product is better than the rest, anyone is bound to be confused, especially when there is ample money involved. Therefore, we have been able to shortlist below the best characteristics of a lubricant you should buy in bulk for your machinery.

A High Boiling Point And Low Freezing Point

Lubricants used in machines which operate under high heat and pressure have a short time to rest. They must use oils that have a high boiling point, as they endure the extreme heat and friction while machines are operational. Similarly, when they have a low freezing point, they will not get saturated early enough, which can cause them to lose their absorption qualities. In this sense, when the lubricant is having a high resistance to a wide range of temperature changes, it usually gives better results.

A High Viscosity Index

Lubricants that have a high viscosity index are better in industrial performance. Viscosity is the thickness and the ability to support the lubrication protection in a hydraulic machine. A lubricant that has a high viscosity index has a longer life and allows the machine to perform better. Lubricants that have a low viscosity should be changed more often, as their capacity to maintain protection is reduced. This also means they cost more in the long run.

Thermal Stability

Thermal stability means how fast the lubricant can decompose when exposed to extreme temperatures. Although, there are other aspects as well that increase the decomposition rate of the lubricants but the thermal stability characteristic deals with the temperature only. In this sense, lubricants that have higher thermal stability are better for industrial-grade usage.

Hydraulic Stability

Hydraulic stability means how well the lubricants perform in terms of chemical decomposition. Chemical decomposition is as damaging to the lubricants as extreme temperature and pressure. Hydraulic stability also shows how good a lubricant can perform in the presence of water particles in the lubricant. Lubricants that have higher hydraulic stability perform much better.


Demulsibility is the level of water vapours present in the lubricant. Less water vapours means better performance. Lubricants that have a lower demulsibility level are much more efficient and productive than the ones that have a higher level. When the water vapour increase in the lubricant, it starts to decompose rapidly, causing the lubricant to lose its protection in the hydraulic systems.

Corrosion Prevention

Industrial-grade lubricants are produced to perform in a heavy-duty setting. For this reason, manufacturers include additives in the lubricants so they can resist corrosion over time. Corrosion and decomposition both weaken the protection attributes of the lubricants with these extra additives; a lubricant can fight corrosion and decomposition for a long time.

High Resistance To Oxidation

Oxidation is a process of lubricant decomposition. Oxidation rates increase as the lubricant experiences high temperatures, presence of catalysts, water and acid in industrial-grade lubricants. In this sense, it’s a good idea to bulk buy lubricants that have a high resistance to oxidation.
