Is Hydraulic Oil Better: 32 or 46
When it comes to hydraulic oil, many people find themselves pondering the eternal question: is 32 better or is 46? It’s a tough call, like choosing between chocolate or vanilla ice cream. But fear not, fellow gearheads, because I’m here to break it down for you in this epic showdown.
What’s in the Numbers, Anyway
The numbers 32 and 46 actually refer to the viscosity of the hydraulic oil. Viscosity measures the oil’s resistance to flow and is indicated by a number followed by “W” for winter or a range of numbers. Think of it as the thickness of the oil.
The Case for 32: The Lightweight Contender
Hydraulic oil 32, like a spry flyweight boxer, is thin and nimble. It has a lower viscosity, making it more suitable for applications where your equipment operates in colder temperatures. It flows easier, allowing for faster startup and better performance in low-temperature conditions. Plus, it’s like the espresso shot of hydraulic oils, providing quick and efficient lubrication.
The Case for 46: The Heavyweight Champion
On the other hand, hydraulic oil 46 is the heavyweight champion of the hydraulic oil world. It has a higher viscosity, making it thicker and more capable of handling heavy loads and higher temperatures. This robust oil shines in hot environments where it can withstand the heat and keep your equipment running smoothly like a well-oiled machine. It’s like the dependable and steady partner you can always count on.
The Final Verdict: It Depends!
Now, before we declare a winner, let me burst your bubble: there’s no “one size fits all” answer. The choice between hydraulic oil 32 and 46 depends on various factors, such as the operating temperature, load requirements, and OEM recommendations.
If you live in a colder climate or your equipment requires swift startup in chilly conditions, 32 might be your go-to option. However, if your equipment operates in higher temperatures or carries heavy loads, 46 is the heavyweight champion you’re after.
The Secret Sauce: Manufacturer’s Recommendations
Remember, the key to finding the best hydraulic oil lies in the Manufacturer’s Manual. Those folks know their equipment inside out, so it’s always a good idea to consult their recommendations. They are like the wise sages who hold the ancient wisdom of the oil gods, guiding you towards the perfect hydraulic oil for your specific needs.
Conclusion: The Battle Rages On
So, my gearhead comrades, the battle for hydraulic oil supremacy between 32 and 46 continues. While you may have hoped for a clear-cut winner, the truth is, it depends on the unique circumstances of your equipment. Whether you go for the lightweight agility of 32 or the heavyweight stamina of 46, consult your Manufacturer’s Manual and let it be your guide in this epic duel. May your hydraulic systems always operate smoothly and your gear stay well-oiled, my friends!
FAQ: Is Hydraulic Oil Better 32 or 46
Last updated: October 2023
Here are some frequently asked questions about hydraulic oil weight and viscosity, specifically comparing ISO 32 and ISO 46 hydraulic oils.

When comparing AW32 and AW46 hydraulic oils, AW46 is the thicker option. The “AW” stands for “anti-wear,” indicating that it contains additives to protect against wear and tear.
What Does ISO VG 46 Mean
ISO VG 46 is a viscosity grade classification established by the International Organization for Standardization (ISO). It signifies that the hydraulic oil has a nominal viscosity of 46 centistokes at 40 degrees Celsius.
Is ISO 46 the Same as AW 32
No, ISO 46 and AW 32 hydraulic oils have different viscosity ratings. ISO 46 is thicker than AW 32, meaning it has a higher viscosity. The choice between the two depends on the specific requirements of your hydraulic system.
What Grade Oil is Best for Hydraulics
The best grade oil for hydraulics depends on various factors such as the equipment manufacturer’s recommendations and the operating conditions. It’s crucial to consult the equipment manual or contact the manufacturer to determine the ideal oil grade for your hydraulic system.
What is the Difference Between ISO 32 and ISO 46
The primary difference between ISO 32 and ISO 46 hydraulic oils lies in their viscosity ratings. ISO 32 is thinner and has a lower viscosity compared to ISO 46. The choice depends on the operating temperature, system requirements, and equipment specifications.
What Viscosity is AW 32 Hydraulic Oil
AW 32 hydraulic oil has a viscosity rating of 32 centistokes at 40 degrees Celsius. It is a lighter weight oil suitable for systems operating within specified temperature ranges.
Is ISO 32 and AW 32 the Same
Although both ISO 32 and AW 32 hydraulic oils have the same viscosity rating, they might have different performance characteristics. ISO 32 indicates the viscosity grade, while AW 32 suggests that the oil includes anti-wear additives.
What Happens if You Use the Wrong Hydraulic Fluid
Using the wrong hydraulic fluid can lead to various issues, such as diminished performance, increased wear and tear, reduced efficiency, and potential damage to the hydraulic system components. It is crucial to use the recommended hydraulic fluid for optimal operation and longevity.
What is AW 46 Hydraulic Fluid
AW 46 hydraulic fluid is a medium weight oil with anti-wear properties. The “AW” designation indicates that it contains additives to protect against wear, making it suitable for hydraulic systems operating under moderate conditions.
Is ISO 46 the Same as AW46
No, ISO 46 and AW46 hydraulic fluids are not the same. While both have a comparable viscosity rating, AW46 includes anti-wear additives that distinguish it from ISO 46, providing increased protection against wear and tear.
