Where To Buy Hydraulic Oil [TOP]
Most hydraulic systems can operate using many different fluids, including multigrade engine oil, automatic transmission fluid and more conventional antiwear (AW) hydraulic oil. Which oil or fluid you choose depends on your equipment and how you plan to use it.

While it is not possible to make one definitive recommendation that covers all types of hydraulic equipment in all applications, there are a few key questions to ask yourself when selecting a hydraulic fluid.
If the hydraulic system is required to operate in freezing temperatures in winter and tropical conditions in summer, then it will likely need multigrade oil to maintain viscosity within permissible limits across a wide operating temperature range.
If fluid viscosity can be maintained in the optimum range, typically 25 to 36 centistokes, the overall efficiency of the hydraulic system is maximized (less input power is given up to heat). This means that under certain conditions, the use of a multigrade can reduce the power consumption of the hydraulic system.
There are some concerns when using multigrade fluids in hydraulic systems. The viscosity index (VI) improvers used to make multigrade oils can have a negative effect on the air separation properties of the oil.1
This is not ideal, particularly in mobile hydraulic systems which have a small reservoir with poor deaeration characteristics. The high shear rates and turbulent flow conditions often present in hydraulic systems destroy the molecular bonds of the VI improvers over time, resulting in loss of viscosity.
If the hydraulic system has a narrow operating temperature range and it is possible to maintain optimum fluid viscosity using a monograde oil, it is recommended not to use a multigrade for the reasons stated above.
DIN 51524; HLP-D fluids are a class of antiwear hydraulic fluids that contain detergents and dispersants; the use of these fluids is approved by most major hydraulic component manufacturers. Detergent oils have the ability to emulsify water and disperse and suspend other contaminants such as varnish and sludge.
The presence of ZDDP is not always seen as a positive because it can chemically break down and attack some metals and reduce filterability. Stabilized ZDDP chemistry has largely overcome these shortcomings, making it an essential additive to the fluid used in any high-pressure, high-performance hydraulic system, such as those fitted with piston pumps and motors.
Skydrol PE-5 is the first name in aviation hydraulic fluids. A Type V, fire-resistant hydraulic fluid specifically formulated to meet the changing needs of the aviation industry, PE-5 offers the longest fluid life of any phosphate ester fluid available today, even under high moisture conditions. With PE-5, you can experience less frequent fluid replacement, reducing disposal volume and decreasing your environmental footprint. Learn more about Skydrol PE-5.
For a lighter-weight hydraulic fluid, you need Skydrol 5. With its lighter weight due to a lower density, you can save fuel and see an overall cost savings. At higher temperatures, you may experience erosion, but Skydrol 5 is the first aviation hydraulic fluid demonstrating erosion-resistance at higher temperatures so that you can experience decreased maintenance and downtime. Learn more about Skydrol 5.
A long service history means a proven track record for a product. Skydrol 500B-4 boasts the longest service history in phosphate ester products, and it is the only commercially available standard-density aviation hydraulic fluid. 500B-4 also offers improved erosion resistance, as it contains the same anti-erosion additive and acid scavenger as LD-4.

Mobil Aero HF Series aviation hydraulic fluids are designed to meet the demanding requirements of commercial and military aircraft applications. These high quality formulations have a long history of excellent performance and provide long, trouble-free service over a wide range of operating conditions. Product features and potential benefits include:
Mobil Aero HFA is a premium quality fluid that meets the quality requirements of the U.S. Military specification MIL-H-5606A (now obsolete). It has a very high VI and is suitable for use at temperatures down to -54 ºC (-65 ºF). While this quality fluid is no longer used by the U.S. Military, it is still used in some older, small private, and commercial aircraft. It is also used in industrial and commercial equipment requiring good fluidity at very low temperatures, where Mobil Aero HFA provides long, trouble-free service over a wide range of operating conditions.
Mobil Aero HF is a premium quality fluid that is approved against the most current version of U.S. Military specification MIL-PRF-5606. It has physical properties very similar to Mobil Aero HFA, and also meets "super-clean" requirements required by modern aircraft hydraulic systems. It is intended primarily for military aircraft, but it is also used as a hydraulic fluid for small private and commercial aircraft, and as a strut fluid in landing gear of large commercial aircraft. It is a NATO Code Number H-515 fluid.
As the pressure in a hydraulic system increases, so does the heat. Without proper cooling, the hydraulic system could overheat and damage the components. Keeping the system properly cooled can extend the hydraulic fluid life, as well as prevent expensive damage to system components. Shop our full selection of thermal transfers and cooler fans below.
