Demystifying Hydraulic Fluids: AW, HLP, and HVI – Which One Does Your System Need?
By Oscar Lubricants
Hydraulic systems are the backbone of modern industry. From manufacturing plants and heavy-duty construction to agricultural and mobile equipment, hydraulic fluids play a critical role in transferring power, reducing wear, and ensuring efficiency.
But not all hydraulic oils are created equal—and choosing the wrong specification can lead to downtime, component damage, or inefficient operation.
At Oscar Lubricants, we’re committed to helping our clients make informed decisions. That’s why we’ve developed a complete range of hydraulic fluids under the Oscar HydraXP line, covering the most in-demand specifications:
Oscar HydraXP AW – Anti-Wear
Oscar HydraXP HLP – DIN 51524 Part 2 compliant
Oscar HydraXP HVI – High Viscosity Index
Let’s break down the differences so you can choose the right oil for your system.
Oscar HydraXP AW – The Reliable Workhorse
AW stands for Anti-Wear, and these fluids are formulated to protect hydraulic components like pumps, valves, and actuators from metal-on-metal contact and abrasion.
Best for:
-
General-purpose industrial hydraulics
-
Moderate temperature conditions
-
Systems not exposed to high-pressure stress or thermal extremes
Key Benefits:
-
Zinc-based anti-wear additives
-
Foam control for smooth operation
-
Corrosion and oxidation resistance
Oscar HydraXP AW is a cost-effective and proven solution for daily hydraulic operations in workshops, manufacturing lines, and construction equipment.
Oscar HydraXP HLP – Elevated Protection with Industry Compliance
When precision and equipment longevity matter, HLP fluids are a step up. These oils meet DIN 51524 Part 2 standards, meaning they undergo tighter quality control and offer improved performance in demanding environments.
Best for:
-
Industrial equipment with servo-valves and fine-tolerance components
-
Moderate to heavy-duty operations
-
Hydraulic systems requiring shear-stable oils
Key Benefits:
-
Excellent wear protection
-
High oxidation stability
-
Protection against rust and demulsibility (water separation)
Oscar HydraXP HLP is ideal for OEM-approved machinery, ensuring you’re not just protecting equipment—you’re also maintaining warranty compliance
Oscar HydraXP HVI – For Temperature Extremes & Mobile Equipment
HVI stands for High Viscosity Index—a technical measure of how well a fluid maintains its viscosity across a wide temperature range.
HVI fluids are formulated with special viscosity index improvers that allow them to remain stable in both cold and hot environments.
Best for:
-
Outdoor/mobile hydraulic systems
-
Cranes, forklifts, loaders, and agricultural equipment
-
Systems operating across seasons or temperature shifts
Key Benefits:
-
Outstanding flow in cold starts
-
Maintains film strength in extreme heat
-
Reduces energy loss due to viscosity thinning
Oscar HydraXP HVI offers a premium-grade solution where performance and fluid stability are mission-critical.
