Where true fluid power comes from

Hydraulic oil for simplified maintenance and less downtime

Machines use oil as hydraulic oil system with precision crafted components to drive a variety of power sources…. After thousands of hours, most equipment is on borrowed time. Major repairs to hydraulic systems are guaranteed to be thousands of dollars whether it’s a hydraulic pump or piston, valves, or bearings. And while the repair bill is a hit to the bank account, it’s compounded by time that machine is no longer earning income.

Hydraulics require proper maintenance. The functions of hydraulic oil deteriorate with the extreme pressure it’s under and contamination by moisture. By employing synthetic hydraulic oil made by the most recognized name in synthetics – AMSOIL – you’ll have less maintenance and downtime and your equipment will keep producing with lower overall costs.

How clean is your hydraulic fluid?

Hydraulic fluid pump

A Bobcat hydraulic system employs a large filter to remove contaminants and moisture that could otherwise damage pumps and gears. Minute particles suspended in oil are highly abrasive, as you’re aware, and etch the polished faces of moving and stationary parts like valves and shafts. Over time, that wear reduces the pressure it can withstand and can no longer hold a seal as well. Then it’s a fast road to failure.

Clean hydraulic oil depends on premium oil filtration, and starting out with the best synthetic hydraulic fluid is a wise idea. AMSOIL includes zinc-based anti-wear and antioxidant additives that resist immense pressure, making them perfect for high- and low-pressure vane and gear pumps and axial piston pumps.

Hydraulic oil for cold weather

AMSOIL synthetic base oils have low pour points and don’t use paraffin for lubricants that gel up in cold weather. AW (anti-wear) Series Oils are ideal for cold-weather applications even without preheating, extreme temperature ranges, and water separates easily from the hydraulic fluid itself. For the end user, that means longer intervals between replacement and lower water contamination that can pit and rust internal surfaces.

AMSOIL offers a wide range of hydraulic oils with a high viscosity index that include:

  • AMSOIL Synthetic Anti-Wear Hydraulic Oil in ISO 22, ISO 32, and ISO 46
  • Synthetic Multi-Viscosity Hydraulic Oil in ISO 22, ISO 32, ISO 46, and ISO 68
  • Biodegradable Hydraulic Oil in ISO 46 for environmentally sensitive applications
  • Hydraulic Filters by Donaldson® and WIX®
  • Hydraulic Tractor Transmission Fluid

Customer Review:

“So far, I am impressed. The test of time will be the deciding factor. This hydraulic oil differs in appearance and viscosity from traditional hydraulic oils. I have trusted AMSOIL for 30 years and use their oils in all my equipment (boats, mowers, 2-cycle, etc.) If it uses oil, it runs on AMSOIL.”
