Hydraulic oil 46 is one of the most widely used grades in modern hydraulic systems due to its balance between protection, fluidity, and thermal stability. Its performance makes it a standard for industrial machinery and mobile equipment.
At American Petroleum, we offer high-performance AW 46 options for multiple sectors in Puerto Rico.
What is hydraulic oil 46?
Hydraulic oil 46 is a hydraulic fluid classified under the ISO VG standard, with a viscosity close to 46 cSt at 40 °C. This value defines its “thickness” and its ability to lubricate and transmit power within a hydraulic system.
Terms such as hydraulic oil 46, ISO VG 46, or ISO 46 hydraulic oil refer to the same viscosity grade. The difference is in how they are used commercially or technically, but they all describe a medium-viscosity hydraulic oil suitable for demanding operations.
What is ISO 46 hydraulic oil used for?
This oil is widely used in industrial machinery, construction equipment, mobile systems, presses, actuators, and hydraulic cylinders. Its medium viscosity allows for stable flow, good lubrication, and wear protection, even when equipment is operating under pressure or in long cycles.
Key properties of hydraulic oil 46
Hydraulic Oil 46 offers an ideal balance between performance, stability, and protection, making it suitable for a variety of working conditions.
Viscosity of hydraulic oil 46
The number 46 indicates that the oil has medium viscosity. In simple terms, it is neither too thick nor too thin, which helps the hydraulic system respond well both at start-up and during operation.
Density of hydraulic oil 46
The density of this oil is usually between 0.87 and 0.89 kg/L. This influences how it moves within pumps and valves, helping the system to operate stably and efficiently.
Hydraulic oil 46 temperature range
ISO 46 performs well at different temperatures: it does not become too thick in the cold or too fluid in the heat. This maintains equipment protection and reliable performance in different conditions.
ISO 46 hydraulic oil weight
Hydraulic oils do not use SAE grades as in motor oils. The number “46” simply indicates its thickness under test conditions and serves as a reference for choosing the right fluid.
ISO 46 hydraulic oil specifications
Hydraulic oil 46 meets essential requirements for industrial and mobile machinery, such as:
- Stable viscosity under ISO VG classification.
- Anti-wear (AW) additives to protect hydraulic components.
- Good oxidation stability to extend oil life.
- Ability to separate water efficiently (demulsibility).
- Protection against corrosion and rust formation.
- Foam control to prevent loss of efficiency.
- Compatibility with fine filtration systems used in industrial applications.

Hydraulic AW ISO 46 for power generation machinery
ISO 46 is used in hydraulic control systems, actuators, and auxiliary components of power generation equipment. Its stability and wear resistance promote reliable operation in industrial environments.
ISO 46 hydraulic oil for bobcat-type equipment
Many compact units and light machinery use ISO VG 46 in their hydraulic systems. However, it is always necessary to confirm the specific grade in the manufacturer’s manual.
Hydraulic AW 46 for mining equipment
This hydraulic grade is ideal for mining machinery, as it withstands high loads, harsh environments, and long cycles. Its anti-wear capacity helps protect pumps, valves, and cylinders.
Oil 46 for industrial hydraulic equipment
Manufacturing, automated lines, presses, and precision hydraulic systems depend on oils with stable viscosity and good protection. ISO 46 meets these requirements for continuous operation.
Hydraulic oil 46 for construction
Excavators, backhoes, cranes, and other construction equipment operate optimally with ISO 46 oils, as this grade maintains an adequate balance between fluidity, protection, and thermal stability.
