Gas turbine in machine

Our Mobil SHC™ 800 Series synthetic turbine oils are designed to provide outstanding low-temperature fluidity and high-temperature stability in the most severe natural gas turbine applications.

These gas turbine oils are formulated to provide superb wear protection across a wider range of operating temperatures compared to conventional turbine oils. Mobil SHC 800 Series synthetic turbine oils can:

  • Reduce the formation of sludge and varnish
  • Keep parts clean and running smoothly
  • Reduce filter plugging
  • Decrease downtime
  • Lower used oil disposal costs by extending oil life

Features and Benefits

The Mobil SHC brand of lubricants are recognised and appreciated around the world for their innovation and outstanding performance. These Mobil SHC synthetic products, pioneered by our research scientists, symbolise the continuing commitment to using advanced technology to provide outstanding products. Mobil brand products have also been the choice for turbine operators worldwide since they were first commercialized more than one hundred years ago. During that period our technical experts have stayed in close contact with OEMs to ensure that our product offerings would provide exceptional performance in the continually evolving turbine equipment designs. Familiarity with evolving designs and operational conditions is a key input to the application of the best lubricant technology in the development of products that will provide the performance demanded by users.

 

One general trend over the years has been to higher power output designs, which can lead to greater thermal stress of the lubricant. This thermal exposure is exacerbated by cycling operation which is employed by gas turbine operators to manage the supply/demand balance of electrical power generation, which results in heat soak-back at each shut-down sequence. Resisting thermal degradation is thus a key property required of a modern gas turbine oil lubricant.

 

To combat high thermal exposure of the oil, our product formulation scientists chose proprietary synthetic base oils for Mobil SHC 800 Series oils because of their exceptional thermal/oxidative resistance capabilities. Our formulators chose specific additives that would maximize the benefits of the synthetic base oils to provide exceptional oil life and deposit control and resistance to thermal and chemical degradation, as well as the balance of the performance features. The synthetic base oil also provides outstanding low temperature fluidity characteristics unmatched by mineral turbine oils and is a key benefit for remote, low temperature ambient applications. Among the numerous benefits and features of Mobil SHC 800 are:
