2. Understanding hydraulic oil categories

Before diving into the risks and benefits of mixing hydraulic oil grades, it’s important to understand what hydraulic oil grades are and how they differ from one another.

Hydraulic oil grades are determined by a rating system developed by the Society of Automotive Engineers (SAE) based on the oil’s viscosity or thickness and flow properties. The viscosity rating of hydraulic oil is measured in centistokes (cSt) at 40°C and 100°C. The two most common hydraulic oil grades are 32 and 46.

Grade 32 hydraulic oil has a lower viscosity and is thinner than grade 46, which means it flows more easily and is more suitable for use in colder temperatures. On the other hand, grade 46 hydraulic oil is thicker and has a higher viscosity, making it more suitable for use in higher temperatures and heavy-duty applications.

It is important to select the correct grade of hydraulic oil for your equipment and its operating conditions to ensure optimum performance and longevity. Using the wrong grade of hydraulic oil can lead to equipment failure or damage, increased wear, and reduced performance. Now that we have a basic understanding of hydraulic oil grades, let’s explore the risks and benefits of mixing 32 and 46 grades.

3. Why mixing different grades of hydraulic oil is an issue

Mixing different grades of hydraulic oil can create many problems that can damage your hydraulic system and cause expensive repairs. The main reason mixing different grades of hydraulic oil is an issue is that different grades have different viscosity indices.

Viscosity refers to the thickness or thinness of a liquid, and the viscosity index measures the change in viscosity with temperature. Mixing different grades of oil can lead to changes in the viscosity and viscosity index of the oil, which can ultimately lead to problems such as poor lubrication, reduced oil flow and increased wear in the hydraulic system.

In addition, mixing different grades of hydraulic oil can also lead to chemical incompatibilities, which can cause the oil to break down and form sludge, clogging filters and reducing system performance.

It is important to understand that different grades of hydraulic oil are formulated for specific applications and mixing them can compromise the performance of the hydraulic system. Therefore, it is recommended that you avoid mixing different grades of hydraulic oil and instead select the correct grade of oil for your particular hydraulic system to ensure optimal performance and longevity.
