Features and Benefits

•  Excellent chemical and oxidation stability help reduce maintenance downtime and costs by contributing to system cleanliness and deposit reduction, which can enable long oil and filter life

•  High resistance to foaming and rapid air release prevent pump cavitation, noisy and erratic operation, which can help reduce pump replacement and increase pump efficiency

•  Reduces varnish formation potential, which can help to increase turbine operation reliability and reduce maintenance costs



Mobil DTE 732 M is a high performance turbine oil designed for use in non-geared gas & steam turbine and turbine compressor applications. Specific applications include:

     •  Steam Turbines – all non-geared

     •  Gas Turbines – all non-geared, including 501F & G series, 701F & G Series

     •  Turbine Compressors – all non-geared
