Where is turbine oil used?

Turbine oil is used in turbine engines such as those in power plants, aircraft, and ships. It is also used in industrial turbines, hydraulic systems, and other machinery that require high-performance lubrication to reduce wear and heat.

What is the difference between turbine oil and hydraulic oil?

Turbine oil is designed for use in turbine engines, providing lubrication, cooling, and corrosion prevention. Hydraulic oil is used in hydraulic systems to transmit power and lubricate components, typically offering different viscosity and chemical properties suited for pressure systems.

What is the viscosity of turbine oil?

The viscosity of turbine oil typically ranges from 2 to 10 cSt (centistokes) at 40°C. The exact viscosity depends on the specific type of turbine oil and its intended application.
