Mobil DTE™ 800 Series

Mobil DTE™ 800 Series turbine oils provide excellent equipment protection, reliable operation and long oil life.

Our Mobil DTE™ 800 Series turbine oils are designed to provide protection, reliable operation, and long oil life in steam turbines, gas turbines and combined-cycle gas turbines.

Because these turbine oils can be used in all turbine types, they provide the ultimate flexibility for operators.

Mobil DTE 800 Series turbine oils have been specially developed to protect turbines from:

  • Stress from extreme temperatures
  • Sludge and varnish deposits
  • Corrosion
  • Water contamination
  • Catalytic effect of system metals
  • arrows

    Extended oil-life formulation helps improve uptime by enabling extended oil drain internvals

  • gears

    Enhanced load-carrying capability provides outstanding protection to help reduce wear and extend component life

  • oil drop

    Excellent demulsibility, air release, and resistance to foaming

  • runtime

    Up to 20,350 hours of oil life with Mobil DTE 846

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 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:
