As you probably have noticed, today’s hydraulic systems are much smaller, run at more extreme temperatures and work harder than ever before. On top of those challenges, many hydraulic systems have to operate through a wide temperature range.
Finding the right hydraulic fluid can make a big difference in ensuring peak performance throughout extreme temperatures and conditions as well as helping to reduce downtime and extend drain intervals. Fortunately, just like our hydraulic systems, the hydraulic fluids we use in them have come a long way in terms of performance. Knowing what to look for is key to getting the right fluid for your system needs.
A number of important factors come into play when choosing the right hydraulic fluid. Of course, you want to make sure the fluid you choose meets OEM specifications and adheres to best practices. You also want to ensure you have a strict maintenance and service protocol to keep your equipment running at its best.

The importance of a high viscosity index…
One important characteristic to look for in a hydraulic fluid is the Viscosity Index (VI)—an important indicator of the oil’s ability to resist changes in viscosity due to temperature variations. The higher the VI, the less the oil’s viscosity will be affected by temperature changes.
For hydraulic equipment that is subject to a wide range of operating temperatures, high-VI fluids are essential to reduce internal pump leakage, eliminate sluggish operation and increase overall operating efficiency.
Return on Investment
HYDREX keeps your operation running smoothly. It lasts up to three times (3X) longer and offers up to two times (2X) better wear protection than the leading hydraulic oil brand. HYDREX also resists oxidative breakdown—which prevents harmful sludge buildup. So, when you use the right fluids in conjunction with your preventive maintenance program, protecting your investment isn’t as daunting as you may think.
