Most customers asked the question：”How to select the right hydraulic oil? ” That is a common question, but easy to be ignored. Selecting the appropriate hydraulic oil is crucial to ensure the optimal performance and longevity of your machinery.

Most lubricant mis-specifications don't lead to sudden and catastrophic failure, but rather they shorten the average life of the lubricated components. In the market, there are plenty of options when it comes to lubricant selection. Generally, the operators will purchase specific hydraulic oil from their machine manufacturer or machine manual. But how do you know if you're using the right hydraulic oil?

a. Understand Your Equipment:
Begin by understanding your machinery's requirements. Factors like system type, load capacity, operating temperature range, and pressure levels play a vital role in determining the right hydraulic oil viscosity, additives, and performance specifications.

b. Viscosity Matters:
Hydraulic oil viscosity directly impacts your equipment's performance. Choose a viscosity grade that aligns with your machinery's operating temperature range. Lower viscosity oils work better in colder environments, while higher viscosity oils are ideal for high-temperature conditions.

c. Compatibility with Additives:
Different hydraulic systems demand specific additives. Antioxidants, anti-wear agents, anti-foaming agents, and corrosion inhibitors are commonly found additives. Ensure that the hydraulic oil you select is compatible with your system's requirements.

d. OEM Recommendations:
Always refer to the manufacturer's recommendations. Original Equipment Manufacturer (OEM) guidelines provide valuable insights into the ideal hydraulic oil specifications for your machinery.

With hydraulic oil (Industrial lubricant), there are three grades for considerations - ISO 32, ISO 46, ISO 68. These specifications are typically determined by the weight and viscosity of the oil. Type of fluid is best for a particular equipment Data Sheet to show how to select the right hydraulic oil for your machinery.

When selecting the appropriate viscosity grade, look for the optimum viscosity required by the hydraulic pump. Check the operating temperature of the pump and see if it falls between the temperature ranges of the lubricant in question. If not, you may need to increase or decrease the viscosity of the lubricant to achieve the desired, optimum viscosity.

If you use oil with a viscosity that’s too high for the climate in which the machine must operate, the oil won't flow properly or lubricate adequately during cold start. If you use oil with a viscosity too low for the prevailing climate, it won’t maintain the required minimum viscosity, and therefore adequate lubrication, on the hottest days of the year.

As you can see, selecting the proper hydraulic oil for the application is not a hard task, but it does require time to research the application, determine the resulting cost and decide which fluid type is best. Just because a machine will run with a particular product doesn't mean that product is optimum for the application.
