Mobil DTE 800 Series
Superior Performance Turbine Oils
Product Description
Mobil DTE 832 and 846 are superior performance turbine oils designed for use in steam turbines, gas turbines
and combined cycle gas turbine (CCGT) applications under the most severe operating conditions. These
progressive products are based on high quality hydrotreated basestocks for exceptional thermal/oxidation
resistance along with specially chosen additives engineered to provide the deposit control and “keep-clean”
performance required by severe duty gas turbines as well as excellent water separability needed for steam
turbine operation. The formulations also include a non-zinc antiwear system to meet the load carrying requirements
of geared turbines.In addition to meeting the separate requirements of modern steam and gas turbine designs,
Mobil DTE 800 Series are excellent choices for combined cycle applications that require a single oil for a gas
turbine and a steam turbine run in tandem. Simultaneously meeting both deposit control and water separation
requirements is the key performance highlight of this advanced lubricant technology. The excellent
thermal/oxidative resistance of Mobil DTE 832 and 846 ensures that they can be operated in the most severe
turbine environments.The performance features of Mobil DTE 800 Series oils translate into excellent equipment
protection, reliable operation, with reduced down-time and extended oil charge life. These products also provide
the ultimate flexibility to the operator because they can be used in all turbine types: steam, gas and
Features and Benefits
Mobil DTE brand mineral-based products have been the choice for turbine operators worldwide for more than
one hundred years. During that period our company’s scientists have maintained the strongest ties with turbine
equipment builders and operators to ensure that the needs of new turbine designs are met or exceeded by our
lubricants. This has required a continual upgrading of Mobil turbine oils and the application of the most appropriate
modern base oil and additive technologyFor modern stationary gas turbines that operate at high power outputs,
exceptional protection against thermal/oxidative degradation and deposit control are key requirements. Severe
operation causes thermal stressing of the lubricant that can result in filter plugging, servo valve deposits or short
oil life. For modern steam turbines, a high level of oxidation resistance is required as well as good water
separability in cases of steam leaks. For combined cycle operation, it is necessary for the lubricant to meet the
needs of both turbine types DTE 800 Series oils offer the following features and potential benefits:

Mobil DTE 832 and 846 are superior performance turbine oils designed for use in steam and gas turbine oil
systems, direct- or gear-coupled and turbine speed control mechanisms. Specific applications include:
• Combined cycle (CCGT) electric power generation applications including those with a common circulation
system for the steam turbine and gas turbine.
• Lubrication of steam turbine or gas turbine units used for electric power generation, natural gas pipeline
transmission, process operations and cogeneration plants.
