Hydraulic oil is a special fluid that assists the functioning of a machine. It is used widely in almost everything, starting with airplanes, farms, trucks, and factories, to mention but a few.
This oil enables mechanisms within machines to circle or rotate, cool them down and transmit force to raise heavy objects such as forklifts lifting large stocks or brakes to stop trucks. However, not all hydraulic oils are similar, and that’s where ISO comes into the picture.
ISO is a shorthand for the International Organization for Standardization. These rules ensure that hydraulic oils are safe and function effectively, as created by this group. With the current ISO standards, it is easier for people to select the right hydraulic oil for their machinery.
In this article, we will learn more about ISO concerning hydraulic oil, why viscosity is the thickness of the oil, and how the standards facilitate the smooth running of the machines.
What is Hydraulic Oil?
Hydraulic oil is a unique fluid type applicable to hydraulic operations’ mechanisms, including flying machines, agricultural lands, big trucks, and industries. It assists in conveying components and cooling them; it aids in ensuring the component’s smooth performance.
In a hydraulic system, the most crucial function of hydraulic oil is transmitting power. Since it does not compress, it carries a lot of force, making it be used in forklifts to lift objects or brakes to stop big trucks.
There is typically some confusion between hydraulic oil and fluid, and there is at least a slight difference. Hydraulic fluids may be additives that include chemicals to avoid forming rust or the inclusion of water to make it less dangerous.
Another is that hydraulic oil is much easier to ignite than new hydraulic fluids, which have been developed to help prevent fire outbreaks.
What is ISO VG?
Viscosity is one of the essential characteristics of oils such as hydraulic oils. All high schools know that it measures the thickness of oil. It is important to note, however, that before 1975, there had been no agreed reference method for determining the viscosity of hydraulic fluids. Due to this, it became very hard for people to choose the right oil to buy for their machines.
Individuals and groups worldwide, including the American Society for Testing and the British Standards Institute, helped develop the ISO VG to correct this. It is common to use this method of determining an oil’s thickness or thinness; therefore, everybody is aware of the system.
Common ISO VG Grades for Hydraulic Oil
Here’s a simple guide to ISO VG grades and what they are usually used for:
- ISO VG 100: Good for big machines that carry heavy loads.
- ISO VG 68: Made for systems that handle heavier-than-normal jobs.
- ISO VG 15: Often used in things like power steering and brakes.
- ISO VG 22: Used for pressurized air tools.
- ISO VG 32: Great for powerful hydraulic tools.
- ISO VG 46: Works well in factories with high-pressure machines.
Why ISO VG Matters
Hydraulic oil changes thickness when temperatures go up or down. When it gets hotter, the oil becomes thinner and flows more easily—like butter melting or oil heating up in a pan. The oil gets thicker and moves slower—like butter or oil in the fridge when it gets colder.
Hydraulic oil sometimes has to deal with really hot or really cold temperatures. If it gets too hot, the oil can break down and leak. It might get too thick or freeze if it gets too cold, damaging the machine.
To stop this from happening, special ingredients are added to the oil to help it stay stable in extreme temperatures. This is measured using something called the Viscosity Index (VI). A higher VI means the oil can handle hotter temperatures without becoming too thin.
Even though ISO VG grades have been around for a long time, picking the right hydraulic oil can still be confusing. It’s also important to check your hydraulic system regularly to ensure the oil is working properly.

What is ISO and Why is it Important?
It is for the International Organization for Standardization, as the name suggests. It is a group that formulates standards and guides to ensure that what people produce, be it goods or services, is safe and functional.
They use these standards everywhere so that people can think similarly. For example, regardless of where a specific item is produced, if conforming to ISO standards, it should function similarly.
How does ISO Affect Hydraulic Oils?
ISO helps ensure hydraulic oils have the right thickness, which is called viscosity. This is important because using the right oil helps machines run smoothly without breaking down. The ISO standards make it easier to choose the correct oil, which helps keep machines working properly for a long time.
What are ISO Viscosity Grades for Hydraulic Oil?
ISO created a system called ISO Viscosity Grades (ISO VG) to show how thick or thin a type of oil is. The grades are numbers like ISO VG 15 or ISO VG 100. A lower number means the oil is thinner, like VG 15, which is good for power steering.
A higher number, like VG 100, means the oil is thicker and is better for heavy machines. These numbers help people pick the right oil for different machines and temperatures.
How do ISO Standards Help Machines Work Better?
ISO standards ensure hydraulic oils meet certain rules, which helps machines work reliably. When machines use the right oil, they run smoothly, even when hot or cold. This means fewer problems, less need for repairs, and a longer machine life. It also helps make sure that machines are safe to use.
Bottom Line
ISO standards are important because they help ensure hydraulic oils work well and keep machines running smoothly. Using the ISO VG grades, people can easily choose the right oil for different types of machines, ensuring they work properly in all kinds of weather.
Whether it’s a tractor, a forklift, or a factory machine, following ISO rules helps everything run safely and last longer. In simple terms, knowing about ISO and its viscosity grades helps you pick the right hydraulic oil.
This way, your machines won’t break down, and you won’t have to spend much on repairs. When you use the right hydraulic oil, you can feel good knowing your machines are working their best.

FAQs
Q1: Why are ISO viscosity grades crucial for the performance of hydraulic systems?
Ans: The thickness of your hydraulic oil, called viscosity, is important for a few reasons. Lubrication means making sure parts can move smoothly without rubbing too much. The right thickness of the oil helps it cover the parts well, protecting them from damage and making them last longer.
Q2: How do ISO standards ensure the quality of hydraulic oils?
Ans: ISO sets rules for how the oils should work well in hot and cold temperatures.
Q3: What should you check for on hydraulic oil labels to verify compliance with ISO standards?
Ans: Look for the ISO VG number on the label. It tells you the oil’s thickness and if it meets ISO rules.
