ExxonMobil Introduces New High-Performance Turbine Oil

New Mobil DTE 700 Series Turbine Oil Can Be Used in Both Gas and Steam Turbines

FAIRFAX, Va.--(BUSINESS WIRE)--

Celebrating a significant milestone in its more than 50-year history of delivering advanced turbine oils to the industrial marketplace, ExxonMobil today announced the global introduction of its new high performance Mobil DTE 700 Series turbine oil.

Formulated with carefully selected basestocks and additives, Mobil DTE 700 is designed for use in light- and moderate-duty gas turbines, as well as steam turbines. Mobil DTE 700 meets or exceeds 19 major industry and OEM's specifications for gas and steam turbine oils, including those of Alstom, GE, Mitsubishi Heavy Industries (MHI) and Siemens.

In extensive testing, Mobil DTE 700 demonstrated exceptional demulsibility retention, oxidation stability and deposit control, three of the most important performance characteristics for turbine oils. In fact, Mobil DTE 700 is one of the few lubricants that have passed the new MHI Dry-Turbine Oil Stability Test, which is designed to measure the deposit control capabilities of turbine oils.

"As the demand for energy continues to increase around the world, today's leading turbine manufacturers are responding to the market needs by developing more efficient and powerful turbine systems," said Glen Sharkowicz, product technical advisor, ExxonMobil Lubricants & Specialties.

"With its balanced formulation, exceptional performance, and ability to be used in both gas and steam turbines, Mobil DTE 700 can help companies maximize the productivity of their turbines."
