Mobil SHC 800 Series
(Synthetic, Oil)
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.
Product Description
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.
Features & Benefits
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 & 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:

Mobil DTE 790 Series (Oil)
Mobil DTE 790 Series lubricants are premium
performance turbine oils that are engineered to meet the requirements
of the most severe steam turbine designs and operation, with maximum
oil charge life.
Product Description
Mobil DTE 790 Series lubricants are premium performance
turbine oils that are engineered to meet the requirements of the
most severe steam turbine designs and operation, with maximum oil
charge life. Mobil DTE 790 Series oils are based on proprietary,
very high quality, hydrotreated base stocks and selected additives
which provide outstanding resistance to oxidation and chemical degradation
over time, which is exemplified by exceptional color stability,
a key factor in assessing oil stability in some regions of the world.
Mobil DTE 790 lubricants also exhibit excellent water separability,
resistance to emulsion formation and anti-foaming characteristics
which provides efficient operation, and good air release properties
which is critical for hydraulic control mechanisms.
The exceptional oxidation stability performance of Mobil DTE 790
oils has resulted in outstanding performance in even the most severe,
and largest capacity steam turbine applications. These products
have an outstanding reputation for equipment reliability and avoiding
unscheduled downtime. This reputation is exemplified by the very
high percent of nuclear turbine operators who choose Mobil DTE 790
lubricants. Their performance in service is also recognized to provide
very long charge life, in excess of conventional turbine oils, and
high resistance to deposit formation and filter plugging. While
