When to Change Hydraulic Fluid in Mobile and Industrial Hydraulic Machinery

Everyone’s feeling the high price of oil right now. One result of increased costs is that changing the oil in your hydraulics pumps is the last thing on many people’s minds. Don’t let economics get in the way of proper equipment care practices. Understand the signs of when you should change your hydraulic oil to protect your machinery and internal components.

Oil Degradation

Oil breaks down over time like all other objects. Your machinery documentation should give you an estimated lifespan of oil in the system. Machinery that undergoes heavy usage will require more frequent lubricant replacements.

Loss of Oil Additives

Extra additives also break down over time, but at a different rate than oil. Some additives last longer than the oil’s lifespan, while others will wear out quickly with continuous usage. Your safest bet is to test a fluid sample and look for any deficiencies. Eventually, you’ll get a feel for when you need more additives.

Temperature Changes

Your hydraulics machinery will vary in performance depending on the season, especially mobile equipment. Hydraulic fluid is sensitive to temperature changes. Letting your machine sit idle in a cold environment will have consequences. Thick oil is difficult for the machine to pump, which could result in leaks, damage, or destruction of internal components.

Find an oil with the right viscosity index to suit your climate. Higher levels of viscosity index mean the oil doesn’t change viscosity easily. That metric alone isn’t always enough information to tell you how the fluid performs at low temperatures, even if its pour point is -30 degrees Celsius.
