Can you use ISO 32 as hydraulic oil?
Application. Catalys Hydraulic AW ISO 32 is used in any hydraulic system of fixed or mobile equipment when ISO grade 32 is recommended.
ISO VG – ISO Grade (where ISO is the International Standards Organisation) – the higher the VG number the more viscous the fluid is. The VG number tells you which hydraulic oil is thicker. This is sometimes referred to as the hydraulic oil weight.
32 is thinner, No. 46 is medium and No. 68 is thicker. Generally speaking, if the temperature is low in winter, use #32 & #46 hydraulic oil with a lower viscosity, and use #68 hydraulic oil with a higher viscosity in summer.
SAE 10W is equivalent to ISO 32, SAE 20 is equivalent to ISO 46 and 68, and SAE 30 is equivalent to ISO 100.
Doing so could compromise the additive performance of both constituents, cause corrosion of component surfaces and lead to increased mechanical wear.
Hydraulic equipment used indoors under normal service conditions generally use a conventional antiwear hydraulic oil with the appropriate viscosity. The most commonly used viscosities are ISO 32, 46, or 68, since these are able to lubricate and protect the system under the normal range of operating temperatures.
AW-32 is neither "better nor worse" than AW-46. The numbers refer only to the viscosity, not to the quality. Quality of the oil is determined by the manufacturer. For Atlas above ground lifts, AW-32 (lower number than AW-46) will flow "better" in colder weather than AW-46.
A: PowerCare AW ISO 32 is not equivalent to the listed products as it is an ISO 32 grade. The other products are thinner and an ISO 22 grade.
ISO 3448 Viscosity class | Kinematic viscosity at 40°C [mm2/s = cSt] | |
---|---|---|
ISO VG 22 | 22 | 24.2 |
ISO VG 32 | 32 | 35.2 |
ISO VG 46 | 46 | 50.6 |
ISO VG 68 | 68 | 74.8 |
Mixing oils with different additive packages is never recommended. Doing so could compromise the additive performance of both constituents, cause corrosion of component surfaces and lead to increased mechanical wear.
Does it matter which hydraulic oil I use?
The main factor when choosing an oil is the viscosity or how thick the oil is in specific conditions. If you select the wrong viscosity grade for your system, you'll find that your hydraulic system doesn't work very efficiently. Ideally, you want to match the viscosity grade to the operating temperature of your system.
CAN I MIX HYDRAULIC FLUIDS? As far as possible, it is always best to avoid mixing different hydraulic fluids. This is because the technical properties could be spoiled by chemical reactions between different additives.

Most hydraulic systems will operate satisfactorily using a variety of fluids. These include engine oil, automatic transmission fluid and oil formulated specifically for the hydraulic compartment.
Hydraulic Jack Oil
This heavy-duty, high-pressure oil protects hydraulic jacks from corrosion and wear.
Common applications for ISO 32 hydraulic oil include: Lifts. Forklifts. Agricultural machinery.
Vegetable oil advantages
Vegetable seed oils hold several advantages over standard mineral oil when used as a hydraulic fluid: Higher flash and fire points — The ASTM D92 Open Cup Flash point of vegetable oils exceeds 320° C.
To answer the original question- Yes, Power steering fluid can be used in a hydraulic jack.

Is there a difference between hydraulic fluid and hydraulic oil?
In summary, hydraulic oil is a type of hydraulic fluid. However, unlike hydraulic oils, hydraulic fluids are used in automatic transmissions and are an alternative to hydraulic oil when flammability is a potential issue involved in operating environments.
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.
- Select the right viscosity at the given operating temperatures to ensure the highest efficiency and to meet the system requirements.
- Select the suitable AW additives: Zn or Zn free anti-wear protection additives.
- Check on viscosity index.
- Petroleum-based or mineral-based fluids are the most widely used fluids today. ...
- Water-based fluids are used for fire-resistance due to their high-water content. ...
- Synthetic fluids are man-made lubricants and many offer excellent lubrication characteristics in high-pressure and high- temperature systems.
R&O stands for rust and oxidation - mineral oils with improved anti-rust and anti-oxidation properties. The ISO classification for these oils is HL. AW stands for anti-wear - R&O oils with an anti-wear additive package. The ISO classification for these oils is HM.
SAE 30 Non-Detergent Lubricating Oil is recommended for use in air compressors and hydraulic systems where the use of non-detergent oils is specified.
#AW 32 hydraulic oil. #AW 46 hydraulic oil. #AW 68 hydraulic oil. #AW Hydraulic oil. #AW Oil.
AW 32 hydraulic fluids have an International Standards Viscosity Grade or ISO VG of 32. This is the thickness of the fluid tested at 40 degrees Celsius. ISO VG 32 has good cold weather flow capabilities and its thickness is equivalent to a SAE 10 weight lubricant.
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.
R&O or RO stands for rust and oxidation - hydraulic oils with improved anti-rust and anti-oxidation properties. The ISO classification for these oils is HL. AW stands for anti-wear. These are RO hydraulic oils with an anti-wear additive package. The ISO classification for these oils is HM.
Is there a universal hydraulic fluid?

With hydraulics, there are three grades for considerations - the viscosity grade and the hydraulic oil type grade 32-46-68. These specifications are typically determined by the weight and viscosity of the oil.
If the Bobcat calls for an industrial grade ISO 32 anti-wear hydraulic oil then, yes it wi… Quality Oil & Gas Co.
In an ideal world, hydraulic fluid would only need to be replaced. However, there are situations in which the hydraulic system really needs to be flushed. A hydraulic flush purges the entire hydraulic system of sludge, contaminants (including water, air, and particulate matter), and degraded hydraulic fluid.
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.
A premium quality Hydraulic oil formulated from solvent refined mineral base oils with additives to provide excellent protection against oxidation, corrosion, wear and foaming.
SAE 30 Non-Detergent Lubricating Oil is recommended for use in air compressors and hydraulic systems where the use of non-detergent oils is specified. Non-detergent oils are also effective for the lubrication of bearings and chains in non-critical once-through systems and as a general purpose shop lubricant.
"Is it all right to mix an R&O hydraulic oil with an AW hydraulic oil in a hydraulic application?" Mixing oils with different additive packages is never recommended. Doing so could compromise the additive performance of both constituents, cause corrosion of component surfaces and lead to increased mechanical wear.
Can I use 46 hydraulic oil instead 32?
Yes as above no problems mixing them. 46 is just a bit thicker so better if you have an older machine that leaks a bit here and there.
