What is HLP 32 oil?
Servosystem HLP oils are high performance hydraulic oils. These oils provide superior antiwear protection, excellent oxidation and thermal stability, outstanding hydraulic stability and good demulsibility. These oils are recommended for sophisticated high performance electro-hydraulic or numerically controlled systems.
How many types of hydraulic oil are there?
There are three main types of hydraulic oils, as described below.
Can you mix ISO 32 and ISO 46?
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. Trending of some oil analysis properties also will be compromised.
How do I choose a hydraulic oil?
Conclusion: how to select the right hydraulic fluid?
- 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.
Which grade oil is used in hydraulic?
Hydraulic oil is used for many of the same reasons as oil but has wider use in automobile systems like automatic transmissions, as well as power brakes and steering. Aircraft systems also require hydraulic fluids….Everything you wanted to know about Hydraulic Oil.

What does VG stand for in hydraulic oil?
viscosity grade
Now to the numbers: 22, 46 and 315 refer to the viscosity grade (VG) of the oil; 22 and 46 are ISO grades and refer to the oil’s kinematic viscosity in centistokes at 40 degrees Celsius, plus or minus 10 percent. So, an ISO VG 46 hydraulic oil has a viscosity of between 41.4 and 50.6 centistokes at 40 degrees Celsius.
