I suppose that TCH is Transmission Converter Hydraulic.
you can not mix hydraulic oil in engine oil because if you do a fire will occure and then you will blow up in a million pieces.
ISO 46 refers to the viscosity grade of hydraulic oil as defined by the International Organization for Standardization (ISO). The number 46 indicates the oil's kinematic viscosity at 40°C, which is approximately 46 centistokes (cSt). This viscosity level is suitable for various hydraulic systems, providing adequate lubrication and performance under moderate temperatures and pressures. ISO viscosity grades help ensure compatibility and effective operation in hydraulic machinery.
C stands for cup of oil
Servo 46 is a hydraulic oil that typically has a viscosity of ISO 46. This means it has a viscosity range of 41.4 to 50.6 cSt at 40°C. It is a medium-viscosity oil suitable for a wide range of hydraulic applications.
The numbers 68 and 46 in hydraulic oils indicate viscosity at 40°C. A 68-grade oil is thicker than a 46-grade oil, affecting flow and performance. Choosing the right viscosity is essential for system efficiency.
Depends on the fire point stated in techincal data sheet for particular item. Generally , Motor Oil start flashing at 220 - 240 degree celsius. Hydraulic Oil flashing at 200 - 200 degree celsius. Jet fuel flash point , 38 C . Open air burning at 260 - 315 C
AW40 hydraulic oil is thicker than AW32 hydraulic oil. The numbers in the designations refer to the viscosity of the oil, with a higher number indicating a thicker oil. Specifically, AW32 has a viscosity of approximately 32 centistokes at 40°C, while AW40 has a viscosity of about 40 centistokes at the same temperature. Therefore, AW40 provides better performance in higher temperature applications where thicker oil is needed.

The flash point of synthetic hydraulic oil typically ranges between 200°F to 400°F (93°C to 204°C), depending on the specific formulation and additives used. This property indicates the temperature at which the oil can produce enough vapor to ignite in the presence of an open flame. It's essential for safety and operational considerations in hydraulic systems, as higher flash points generally indicate better thermal stability and safety in high-temperature applications. Always refer to the manufacturer's specifications for precise flash point values.
One of the heathiest oil is the olive oil. See the related link below. (Click on "Olive oil link)
The flash point of ISO 32 hydraulic oil typically ranges from approximately 200°C to 220°C (392°F to 428°F). This high flash point indicates a relatively low risk of ignition under normal operating conditions. However, specific values can vary based on the formulation and additives used in the oil, so it's always best to consult the manufacturer's data sheet for precise information.
