What is the difference between ISO 68 and ISO 100 hydraulic fluid?
ISO 68 Hydraulic Oil – ISO VG 68 Hydraulic Fluid is designed for use in systems which require a large load-carrying ability. ISO 100 Hydraulic Oil – ISO VG 100 Hydraulic Fluid tends to be used in industrial machinery with heavy loads. Please note that the above examples are just a rough guide and some grades may cross over.
What is the best cross reference for hydraulic fluid?

Cross reference ISO VG 32 Grade Hydraulic Fluid Cross reference ISO VG 46 Grade Hydraulic Fluid
What are the different types of hydraulic oil?
ISO 22 Hydraulic Oil – ISO VG 22 Hydraulic Fluid is generally used in airlines for air tools etc. ISO 32 Hydraulic Oil – ISO VG 32 Hydraulic Fluid is ideal for use in high-powered machine tools. ISO 46 Hydraulic Oil – ISO VG 46 Hydraulic Fluid is normally required for industrial plant working under high-pressure etc.

What is ISO 22 hydraulic oil?
Hydraulic 22 is part of Crown Oil’s range of premium-grade mineral-based hydraulic oils with good anti-wear properties providing protection in the most demanding of systems while still meeting ISO standards for hydraulic oil. This hydraulic fluid is rust, corrosion and oxidation inhibited.
What weight is ISO 22?
ISO 22 HVI Hydraulic Oils are similar in thickness to SAE 5W at operating temperature.
What ISO is universal hydraulic oil?
ISO 68 Hydraulic Oil – ISO VG 68 Hydraulic Fluid is designed for use in systems which require a large load-carrying ability.
What viscosity is ISO 22?

What does ISO mean on hydraulic oil?
International Standards Organization Viscosity GradeISO VG stands for “International Standards Organization Viscosity Grade” and is reported in numbers ranging from 2 all the way up to 1500. This number is critical because a lubricant’s viscosity is the single most important factor when selecting the right oil for your machinery.
Is 022 hydraulic oil?
AW 22 Hydraulic Oils contain a zinc anti-wear additive that is designed to protect hydraulic systems and equipment by reducing wear. The quality of the base oil controls corrosion, oxidation, and suppresses foam and aeration. AW 22 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 22.
What is the difference between 22 and 32 hydraulic oil?
ISO 22 Hydraulic Oil – ISO VG 22 Hydraulic Fluid is generally used in airlines for air tools etc. ISO 32 Hydraulic Oil – ISO VG 32 Hydraulic Fluid is ideal for use in high-powered machine tools.
What is the difference between universal tractor fluid and hydraulic fluid?
They are designed for applications in different tractor and heavy-duty machinery components. Hydraulic oil transfers power, while tractor fluid lubricates the moving parts within a transmission. Choosing the right tractor fluid and hydraulic oil can have an effect on the performance of your equipment.
Does it matter what hydraulic fluid you use?
Most hydraulic systems can operate using many different fluids, including multigrade engine oil, automatic transmission fluid and more conventional antiwear (AW) hydraulic oil. Which oil or fluid you choose depends on your equipment and how you plan to use it.
What is the difference between SAE and ISO?
There is no significant difference between ISO (International Standards Organisation) or SAE (Society of Automotive Engineering). Both organisations provide test standards to allow the ability to reliably compare published filter ratings among manufacturers.
What are the ISO viscosity grades?
The ISO viscosity classification uses mm2/s (cSt) units and relates to viscosity at 40oC. It consists of a series of 18 viscosity brackets between 1.98 mm2/s and 1650 mm2/s, each of which is defined by a number. The numbers indicate to the nearest whole number, the mid points of their corresponding brackets.
What is the viscosity of hydraulic oil?
The viscosity of a hydraulic fluid is a critical element in the transfer of hydraulic power. The ideal viscosity range for a fluid—and thus its highest efficiency—is usually between 10 and 100 mm²/sec, depending on the application.
What is the weight of hydraulic fluid?
The density of hydraulic oils is about 0.8-0.9 g/ml or 800-900 kg/m3. How much does hydraulic oil weigh per gallon? As a rule of thumb, the average hydraulic oil weighs about 6.7-7.5 pounds per gallon.
What is ISO 32 hydraulic fluid?
Hydraulic 32 is part of Crown Oil’s range of premium-grade mineral-based hydraulic oils with good anti-wear properties providing protection in the most demanding of systems while still meeting ISO standards for hydraulic oil. This hydraulic fluid is rust, corrosion and oxidation inhibited.
What kind of oil do you put in a dump trailer?
Use a good grade of non-foaming hydraulic fluid with anti-corrosion and anti-wear additives such as Napa AW-68 hy- draulic fluid.
Can you use thicker oil in hot weather?
In very cold weather, you may want to use a thinner hydraulic oil, because the cold thickens your oil. However, even if it is extremely hot, you should not use a thicker oil.
Can ISO 46 replace SAE oil?
You may notice that ISO 46 can replace both 15W and 20W SAE oils. This is because the ISO specifications are broad, and they overlap with SAE weights in some cases. If your tractor or truck calls for 20W hydraulic oil, it may be best to use the thicker ISO 68 in hot temperatures and thinner ISO 46 in cold weather.
