Mobil DTE 732 M2
Mobil DTE 732 M2 is a next-generation high-performance turbine oil specifically developed for use in Mitsubishi Heavy Industries (MHI) non-geared gas and steam turbines, including applications with advanced bearing materials such as PEEK. Formulated with high-quality base oils and a carefully balanced additive system, it is engineered to meet demanding high-temperature turbine requirements while delivering extended service life and reliable performance.
One of the key advantages of Mobil DTE 732 M2 is its excellent oxidation and chemical stability. The formulation resists degradation under high temperature operating conditions, helping to reduce deposit and varnish formation. This contributes to cleaner systems, improved turbine reliability and extended oil and filter life.
Mobil DTE 732 M2 also offers strong resistance to foaming and excellent air release properties. These characteristics help prevent pump cavitation, noisy operation and system instability, ensuring smooth and efficient turbine performance while reducing equipment wear and maintenance requirements.
Another important benefit of Mobil DTE 732 M2 is its ability to minimise varnish formation. This helps maintain system cleanliness and supports long-term operational reliability, particularly in high-temperature turbine environments where deposit control is critical.
Mobil DTE 732 M2 is recommended for use in non-geared gas and steam turbines, including heavy-duty and multi-shaft turbine systems, as well as turbine compressors. It is particularly suited to applications requiring compliance with Mitsubishi Power specifications such as MS04-MA-CL005, CL001 and CL002, ensuring compatibility with modern turbine designs and operating requirements.
Physical characteristics include a kinematic viscosity of approximately 31.0 mm²/s at 40°C and 5.8 mm²/s at 100°C, with a viscosity index of around 131. Mobil DTE 732 M2 has a flash point of approximately 233°C and a pour point of approximately −15°C. It also offers excellent oxidation resistance, with a turbine oil stability life of approximately 10,000 hours and strong resistance to rust and corrosion, supporting long-term reliable operation.
