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.
Increase in oil temperature
The formation of foam in the hydraulic system causes a kind of carpet to form on the surface. This carpet prevents the hydraulic oil from dissipating the heat generated, which is why the oil can heat up unnecessarily.
Oil loss and insufficient lubrication
Furthermore, the foam can swell through much smaller openings. Over time, this leads to oil loss and thus to a lack of lubrication of the various particles. Therefore, foam occurring in hydraulic oil should be stopped as soon as possible.
The Midland hydraulic oils all contain so-called anti-foam additives in the perfect dosage, so that there is certainly no foaming 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
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.
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.
