Mobil SHC 800 Series turbine oils are designed specifically to meet the needs of the most severe industrial gas turbine applications with a nominal 10,000 hour TOST life. They are recommended for the lubrication of land-based gas turbines, particularly units under 3,000 hp used as standby power units, and in some types of total energy and combined cycle (gas/steam) systems. This innovative product family is formulated from wax-free synthesized hydrocarbons and a unique additive system. This formula provides outstanding low temperature fluiditiy and exceptional resistance to degradation at high temperatures well beyond the capabilities of premium quality mineral oils. Mobil SHC 800 Series lubricants also provide excellent antiwear properties as well as protection against rust and corrosion plus good air release performance and resistance to foaming.

These characteristics provide superior resistance to thermal/oxidative degradation during the heat soaking period after shutdown and permit rapid oil circulation at low temperatures during start-up. Degradation resistance is a key attribute in avoiding harmful deposits that can interfere with lubrication supply to the bearings or foul critical servo-valves. This is a particular issue when gas turbines are running in cycling mode and experience multiple thermal stress cycles. Since low temperature fluidity and high viscosity index are inherent characteristics of the fluids, they do not change in service as a result of mechanical shearing or repeated cycling from low to high temperatures. Mobil SHC 800 Series oils are fully compatible with mineral oils, but admixture will detract from its superior performance properties

These progressive products, which have been proven in very severe gas turbine service over many years, are preferred by users because of their outstanding stability and equipment protection under the most severe, high temperature conditions, and because of their easy start-up at low ambient temperature. This performance results in excellent equipment reliability and minimized downtime.

The Mobil SHC brand of lubricants are recognised and appreciated around the world for their innovation and outstanding performance. These molecular design 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. Familarity 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 wax-free nature of the synthetic base oil also provides low temperature fluidity characteristcs unmatched by mineral products and is a key benefit for remote, low ambient applications. Among the numerous benefits and features of Mobil SHC 800 are:

Features	Advantages and Potential Benefits

Mobil SHC 800 Series turbine oils are designed specifically to meet the needs of the most severe industrial gas turbine applications and ancillary equipment. Specific applications include:

• Severe stationary gas turbine applications, particularly units under 3,000hp, for stand-by power generation.
• Industrial gas turbines operating in low ambient and remote areas
• Total energy systems

MOBIL SHC 800 Series is manufactured from high quality synthetic base oil, carefully blended with selected additives. As with all petroleum products, good personal hygiene and careful handling should always be practiced. Avoid prolonged contact to skin, splashing into the eyes, ingestion or vapour inhalation. Please refer to our Imperial Oil Material Safety Data Sheet for further information.
