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 technology.

For 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:


Features Advantages and Potential Benefits
Meets or exceeds both gas turbine and steam turbine requirements of key builders Avoids lube misapplication and costly change-out
Reduces inventory costs
Excellent thermal/oxidation stability Reduced downtime, more reliable operation
Extended oil charge life; lower product costs
Excellent antiwear protection Excellent protection for geared turbines (gas- and steam-), lower maintenance and replacement costs
Extended equipment protection and reduced replacement costs
Excellent demulsibility Efficient system operation and reduced maintenance


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.
