If a hydraulic oil foams, this can be prevented to a certain degree with an antifoam additive. However, it is important to note that more of this additive does not equate to better foaming behavior. Therefore, the unauthorized use of antifoam additives is rather discouraged and it is recommended to change the hydraulic oil completely. This ensures that the hydraulic oil in the system is clean again and that its functionality is not affected by mixing with other components.
There are many reasons why foaming can occur in the hydraulic system. Often the reason is a change in the surface tension of the oil. Such a change can occur due to mixing of differently formulated oils, impurities or oil oxidation. However, the operating temperature and its effect on viscosity, as well as the type of air intake, can also be the reason for the formation of foam. Often, excessive use of additives also promotes the formation of foam.
The Midland hydraulic oils all contain so-called anti-foam additives in the perfect dosage, so that there will certainly be no foam formation after an oil change.

More questions about Hydraulic Fluid
Due to this variety of tasks, there are different hydraulic oils depending on the application area. The DIN 51524 standard classifies hydraulic oils by defining minimum requirements.
Hydraulic fluids perform a wide range of tasks. Depending on the application area, these may vary further. Basically, however, the following are the main tasks of hydraulic oils:
- Transmission of power in the hydraulic system
- Lubrication
- Protect against corrosion, wear, and deposits
- Cooling and cleaning In addition
Foam in the hydraulic system is known to be something that is not desirable. The reason for this is that the foam can cause the oil temperature to heat up unnecessarily. In addition, the foam can cause oil loss, which leads to insufficient lubrication.
No, engine oils should not be used in the hydraulic system because they are designed for different tasks and thus cannot normally perform the tasks of the other.
