INTRODUCTION

The Fluid That Moves the World

There is something quietly extraordinary about hydraulic oil. It flows through the steel veins of the world's most powerful machines — excavators tearing into mountainsides, aircraft wings folding with precision, steel mill presses shaping raw metal into civilization's building blocks — yet it rarely receives the recognition it deserves. Hydraulic oil is not merely a lubricant. It is the silent force multiplier that makes modern industrial life possible.

At its core, hydraulic oil is a precisely engineered fluid designed to transmit power, protect mechanical components, dissipate heat, and carry away contaminants — all simultaneously, and often under extreme pressure and temperature conditions. These specially formulated fluids prevent corrosion, transfer heat, remove contaminants, and lubricate equipment, engineered to perform reliably under pressure differentials, operational stresses, and wide temperature variations.

"When pressure is applied to an incompressible fluid, the pressure is the same in all directions." — Blaise Pascal, 1653

HISTORY

A History Forged in Industry

The Word Itself — Where “Hydraulic” Comes From

Before the machines, before the presses and pipelines, there was a word — and that word carries within it an entire civilisation’s understanding of water and power. "Hydraulic" is one of those rare technical terms whose etymology tells its own story, bridging ancient Greek ingenuity and modern engineering.

 

Greek Root	Transliteration	Meaning	Wider Language Family
ὕδωρ  (hydōr)	hýdōr	Water	Proto-Indo-European *wed- — same root as: water, wet, wash, vodka, hydrant, hydrogen
αὐλός  (aulós)	aulós	Pipe / Tube / Hollow Reed	Also denotes the ancient Greek flute — a hollow channel through which air (or fluid) flows
ὑδραυλικός  (hydraulikós)	hydraulikós	"Of the Water Pipe"	Originally described the hydraulis — the water-powered pipe organ invented by Ctesibius of Alexandria (~270 BC)

The word's journey from ancient Greek to modern English followed a clear path: from Greek ὑδραυλικός (hydraulikós) into Latin as hydraulicus, then into French as hydraulique, and finally into English around 1600 — where it initially meant “about fluids in motion.” The Romans extended the term beyond music to describe all manner of water-powered engines, and by the Industrial Revolution, it had become the defining word for an entire branch of engineering.

Remarkably, the word “hydraulic” was born not from warfare or farming — but from music. The hydraulis, invented by the Greek engineer Ctesibius of Alexandria around 270 BC, was a pipe organ powered by water pressure — the world’s first keyboard instrument and, in essence, the world’s first application of fluid pressure to do mechanical work. From that water-driven musical pipe of ancient Alexandria to the hydraulic oil-filled systems powering the world’s greatest machines today — the word has carried its meaning faithfully across more than two thousand years.

A Timeline of Hydraulic History

~270 BC  Ctesibius — The Hydraulis, First Fluid-Powered Machine

The Greek engineer Ctesibius of Alexandria invented the hydraulis — a water-powered pipe organ and the world's first keyboard instrument. It used pressurised water to force air through pipes, producing music. This was the earliest known machine to harness fluid pressure for mechanical work, and the instrument that gave 'hydraulic' its name.

Ancient Times: Water as the Original Hydraulic Fluid

Ancient Egyptians and Greeks used water as a hydraulic fluid for irrigation and flood control. Water power was used in Mesopotamia and Egypt since 6000 BC, and the first water clock appeared around 2000 BC. Water was abundant, free, and effective enough for basic force transmission tasks.

1653 Pascal Lays the Scientific Foundation

French mathematician Blaise Pascal (1623–1662) presented what became known as Pascal’s Law: “When pressure is applied to an incompressible fluid, the pressure is the same in all directions.” This single insight would take over a century to find its full industrial expression, but when it did, it changed everything.

1738 Bernoulli Puts Theory into Practice

Swiss mathematician Daniel Bernoulli bridged the gap between Pascal’s theoretical law and real-world engineering, becoming the first to use pressurised water practically in mills and pumps — demonstrating that fluid pressure could be harnessed as a genuine and controllable mechanical force.

1795 Joseph Bramah & the First Hydraulic Press

English inventor Joseph Bramah (1748–1814) patented his “Hydrostatic Machine” — the Bramah Press — applying Pascal’s Law to create the world’s first practical hydraulic press. It automated printing presses, cranes, cutting and stamping machines. The hydraulic age had truly begun.

1808 Mary Randall Vickers — A Legacy Begins

Left a widow with eight children, Mary Randall Vickers courageously continued the family business — guided by her Methodist values of honesty, loyalty, and kindness. She boldly invested in a steam engine and entered a business partnership. When her son Benjamin Randall Vickers joined her, their fortunes changed decisively. The foundation of what would become one of the most respected names in lubricant history was laid.

1828 Vickers Oils — Trading Begins in Leeds

Benjamin Randall Vickers started trading in Leeds as an agent for oils and soaps, serving local woollen and worsted yarn processors. In the late 1850s, oil manufacturing and refining began, supplying textile and leather manufacturers. Insurance companies demanded oils passing a combustibility test Vickers had developed — an early example of setting industry standards.

1882 Vickers Invents the First Marine Lubricant

A sea voyage to America inspired Benjamin Threlfall Vickers to develop an oil that could lubricate ships’ propellers even in contact with seawater. This New Engine Oil (NEO) became the forerunner of today’s world-leading HYDROX BIO marine lubricant grades.

Early 20th Century Water Gives Way to Mineral Oil

Scientists replaced water with mineral oil as the hydraulic base stock of choice. Its higher boiling point, natural lubrication properties, and resistance to corrosion made it vastly superior for the increasingly sophisticated machines of the industrial age. The modern era of hydraulic oil had truly arrived.

WWI & WWII War Accelerates Hydraulic Innovation

Demand for high-pressure fluid power components surged — particularly in naval manufacturing during WWI — leading to the establishment of an entire dedicated industry. By WWII, hydraulic systems were embedded in aircraft controls, naval gun turrets, and heavy military machinery.

2002 Vickers Oils — World’s First Biodegradable Sterntube Oil

After years of R&D, Vickers Oils launched HYDROX BIO — the world’s first commercially available biodegradable stern tube lubricant. It quickly became the industry standard. In 2013, the US EPA mandated such Environmentally Acceptable Lubricants (EALs) for vessels in US waters — validating what Vickers had pioneered over a decade earlier.

Today Vickers Oils — 6th & 7th Generation, 60+ Countries

Vickers Oils remains a private, independent company led by the 6th and 7th generations of the founding family, delivering high-performance specialty lubricants to over 60 countries worldwide, maintaining its founding values of technical excellence, customer service, and environmental responsibility.

Understanding Hydraulic Oil Standards

Hydraulic oil is governed by a layered system of international, national, and OEM-specific standards. Understanding these standards is essential for selecting the right fluid, maintaining equipment warranties, and ensuring optimal system performance. There are two complementary frameworks every engineer and buyer must understand: ISO Performance Categories (what additives and properties the oil has) and ISO Viscosity Grades (how thick the oil is).

 

Framework 1 — ISO 6743-4: Performance Category Classification

The International Organization for Standardization’s ISO 6743-4 is the global reference standard for classifying hydraulic fluids by their formulation and performance characteristics. Each category is designated by a two-letter code under the “Family H” (Hydraulic Systems) classification. The five primary mineral-oil categories are governed by ISO 11158:2023.

ISO HH — Base Mineral Oil

HH BASE MINERAL OIL The most basic category — pure refined mineral oil with no performance additives whatsoever. No antioxidant, no rust inhibitor, no anti-wear protection. Largely obsolete in modern industrial practice. ⚙ Application: Low-pressure, non-critical legacy systems only

 

ISO HL — Inhibited Mineral Oil

HL INHIBITED MINERAL OIL Refined mineral oil with anti-oxidation and anti-rust (corrosion inhibitor) additives. Resists oil degradation and protects metal surfaces from rust. No anti-wear additive. ⚙ Application: Light-duty hydraulic systems, machine tools, low-pressure circuits

ISO HM / HLP — Anti-Wear Hydraulic Oil

HM / HLP ANTI-WEAR HYDRAULIC OIL HL properties PLUS anti-wear (AW) additives — typically zinc dialkyldithiophosphate (ZDDP). This is the most widely used hydraulic oil in the world, offering comprehensive protection for high-pressure systems. ⚙ Application: Industrial presses, excavators, manufacturing machinery, mobile hydraulics

ISO HV / HVLP — High Viscosity Index Oil

HV / HVLP HIGH VISCOSITY INDEX OIL HM properties PLUS viscosity index (VI) improvers. Maintains stable viscosity across a wide temperature range — critical where ambient temperatures fluctuate dramatically between startup and operating temperature. ⚙ Application: Mobile equipment in cold climates, outdoor machinery, construction in variable temperatures

 

ISO HG — Anti-Stick-Slip Oil

HG ANTI-STICK-SLIP OIL HM properties PLUS friction modifier additives that prevent "stick-slip" motion in hydraulic slideways and guide surfaces. Specialised use for precision machine tools with combined hydraulic and slideway systems. ⚙ Application: CNC machine tools, slideway systems, precision manufacturing equipment

HF Series — Fire-Resistant Fluids

HFA / HFB / HFC / HFD FIRE-RESISTANT FLUIDS A family of fire-resistant hydraulic fluids: HFA (oil-in-water emulsions), HFB (water-in-oil emulsions), HFC (water glycol solutions), and HFD (anhydrous synthetic fluids such as phosphate esters). Each trades some lubricity for fire safety. ⚙ Application: Steel mills, die casting, foundries, mining, aviation ground support

 

HEES / HETG — Biodegradable Fluids

HEES / HETG BIODEGRADABLE FLUIDS HEES (synthetic ester-based) and HETG (triglyceride/vegetable oil-based) biodegradable hydraulic fluids. Rapidly biodegradable, low aquatic toxicity, and in many cases equal or superior performance to mineral oils. ⚙ Application: Forestry, agriculture, marine, waterway maintenance, environmentally sensitive sites

Key Differences Between Main Performance Categories

Grade	ISO Equiv.	Anti-Oxidant	Anti-Rust	Anti-Wear	High VI	Friction Mod.
HH	ISO HH	✗	✗	✗	✗	✗
HL	ISO HL	✓	✓	✗	✗	✗
HM / HLP	ISO HM	✓	✓	✓	✗	✗
HV / HVLP	ISO HV	✓	✓	✓	✓	✗
HG	ISO HG	✓	✓	✓	✗	✓ (friction)
HLPD	ISO HM+D	✓	✓	✓	✗	Dispersant

 

Framework 2 — ISO 3448: Viscosity Grade Classification (ISO VG)

The ISO VG (Viscosity Grade) system classifies hydraulic oils by their kinematic viscosity, measured in centistokes (cSt) at 40°C. The number in each grade represents the approximate midpoint viscosity at that temperature. Higher numbers mean thicker, slower-flowing oil. The most commonly used grades in hydraulic systems are ISO VG 32, 46, and 68 — together covering the vast majority of industrial and mobile applications worldwide.

ISO VG Grade	Viscosity @ 40°C (cSt)	Temperature Range	Primary Applications
ISO VG 15	~15 cSt	Very cold: −20°C to +20°C	Power steering, spindle hydraulics, high-speed circuits
ISO VG 22	~22 cSt	Cold: −10°C to +30°C	Small high-speed tools, precision servo systems, cold-climate startup
ISO VG 32	~32 cSt	Cool to moderate: 0°C to 40°C	Machine tools, textile machinery, light industrial systems, cold-climate mobile equipment
ISO VG 46	~46 cSt	Moderate: 10°C to 55°C	MOST WIDELY USED GRADE GLOBALLY. Industrial presses, construction equipment, manufacturing machinery, and general-purpose mobile hydraulics
ISO VG 68	~68 cSt	Warm to hot: 20°C to 70°C	Heavy-duty presses, large excavators, slow-speed high-pressure systems, and hot climates
ISO VG 100	~100 cSt	Hot: 30°C to 80°C+	Extreme industrial applications, large slow-moving cylinders, steel mill equipment
ISO VG 150+	150+ cSt	Very hot / heavy load	Specialty high-load applications, offshore equipment, large hydraulic presses

How to Read a Full Hydraulic Oil Designation

A complete hydraulic oil specification combines both the ISO performance category and the ISO VG viscosity grade:

 

ISO VG 46 HM — An anti-wear hydraulic oil (HM) with a kinematic viscosity of approximately 46 cSt at 40°C. This is the single most common hydraulic oil specification found in general industrial use worldwide.

 

ISO VG 32 HV — A high-viscosity-index anti-wear oil in a lighter viscosity grade, suited for cold-climate mobile equipment that must start and operate reliably across a wide temperature range.

OEM and Industry-Specific Specifications

Beyond ISO and DIN standards, major hydraulic equipment manufacturers publish their own OEM approval specifications that oils must pass before being approved for use in their equipment. These specifications often include demanding pump bench tests and field trial requirements that exceed ISO minimums. Always check your equipment manual for the required OEM approval before selecting an oil.

 

OEM Specification	Description & Scope
Eaton-Vickers M-2950-S	Mobile hydraulic systems require the demanding Vickers vane pump wear test (35VQ25)
Eaton-Vickers I-286-S	Stationary/industrial hydraulic systems; rigorous pump wear test requirements
Parker Hannifin (Denison) HF-0	Highest tier: full anti-wear, filterability, and full compatibility requirements
Parker Hannifin (Denison) HF-1 / HF-2	Progressive approval tiers for anti-wear hydraulic oils; HF-2 is the most widely specified
Bosch Rexroth RE 90220	Comprehensive specification for piston and gear pump systems, widely used in Europe
Cincinnati Milacron P-68 / P-69 / P-70	Machine tool hydraulic approvals for ISO VG 32, 68, and 46, respectively

DIN 51524 Part 2 (HLP)	German national standard; equivalent to ISO HM; widely used across European OEMs
DIN 51524 Part 3 (HVLP)	High-VI version of HLP; required for variable-temperature mobile systems
ASTM D6158	American standard for mineral-based hydraulic oils, common in North American equipment
US Steel 127 / 136	Industry-specific approvals for steel manufacturing hydraulic applications
ISO 15380	Environmentally acceptable (biodegradable) hydraulic fluids classification
US EPA VGP 2013	Mandates Environmentally Acceptable Lubricants (EALs) in US waters for marine vessels

Types of Hydraulic Oils

Mineral-Based Oils

The most widely used category globally — derived from refined crude oil fractions. Cost-effective and broadly compatible, they perform excellently in construction equipment, agricultural machinery, and standard industrial systems. Their viscosity index typically ranges from 90 to 110. Limitations include lower oxidation resistance at elevated temperatures and environmental concerns due to their non-biodegradable nature.

Synthetic Oils

Chemically engineered for superior performance — offering exceptional thermal stability, wider operating temperature ranges (viscosity index often exceeding 150), and longer service life. Preferred in aviation, high-pressure industrial systems, and extreme-environment applications. Key synthetic types include Polyalphaolefins (PAO), phosphate esters, polyol esters, and polyalkylene glycols (PAG).

Bio-Based & Biodegradable Oils

The fastest-growing segment. Advances in bio-based hydraulic fluid technology have evolved to the point where many bio-hydraulic fluids now offer the same or better performance than conventional petroleum or synthetic hydraulic fluids, while offering a decisive environmental advantage. Vickers Oils, as a pioneer in this space since 2002, has demonstrated that environmental responsibility and high performance are not mutually exclusive.

Key Properties of Hydraulic Oils

Property	Description	Why It Matters
Viscosity	Resistance to flow at operating temperature	Core to pressure transmission and film strength, wrong viscosity causes pump cavitation or excessive heat
Viscosity Index (VI)	Rate of viscosity change with temperature	High VI oils maintain stable performance across temperature extremes — essential for outdoor mobile equipment
Oxidation Stability	Resistance to chemical breakdown under heat	Determines service life; oxidation produces acids, sludge, and varnish that damage system components
Anti-Wear (AW)	Additive film protection under high load	Protects pumps, valves, and cylinders — especially vane and piston pumps operating at high pressure
Corrosion Inhibition	Protection of ferrous and non-ferrous metals	Guards all metal surfaces; of particular importance for yellow metals (brass, bronze) sensitive to certain additive chemistries
Foam Resistance	Ability to release entrained air quickly	Prevents spongy response, cavitation damage, and power loss caused by air bubbles in the fluid
Demulsibility	Water separation capability	Ensures water contamination is expelled rather than emulsified — preventing corrosion and additive depletion
Biodegradability	Rate of natural breakdown in the environment	Environmental and regulatory compliance is increasingly mandated for marine, forestry, and waterway applications
Cleanliness (ISO 4406)	Particle contamination level	Critical for servo valves and precision components, contamination is the leading cause of hydraulic system failure
