Mobil Pegasus 1
Gas Engine Oil
Product Description
Mobil Pegasus™ 1 is a high performance synthetic gas engine oil designed to meet the
highest performance requirements of the most demanding naturally aspirated and
turbocharged stoichiometric and lean-burn gas engines. It is formulated from wax-free
synthetic base oils and a balanced additive system to provide performance that is unattainable
with conventional mineral oil-based gas engine oils. The potential benefit is an improved
bottom line through improved engine and oil life, reduced maintenance costs and lower fuel
costs.
The unique formulation of Mobil Pegasus 1 minimises ash deposits, piston land and ring belt
deposits, liner scuffing, and valve seat and valve face wear. It has outstanding resistance to
oxidation and the inherently high viscosity index of the synthetic base oil components ensure
a protective lubricant film at high temperatures well above the limit for mineral oil-based
products. Mobil Pegasus 1 exhibits low volatility, a performance characteristic that helps
reduce oil consumption and improve valve lubrication performance measurably. Its unique
viscometrics and low traction coefficient reduce power losses and provide potential fuel
economy benefits, particularly under variable load, speed and temperature conditions.
Features and Benefits
The state-of-the art technology used in Mobil Pegasus 1 is designed to provide a high level of
engine performance in a wide range of high-output gas engines. Its outstanding oxidation
resistance and thermal stability provide extended service life for both the engines and the oil.
In addition, the unique properties of Pegasus 1 will result in lower internal friction under cold
start-up and hot running conditions resulting in reduced wear and potentially lower fuel
consumption. The use of this product will result in lower maintenance costs through its
extended service life capability, reduced filter costs and improved engine life.

Mobil Pegasus 610
Gas Engine Oil
Product Description
Mobil Pegasus 610 is a high performance gas engine oil primarily intended for the lubrication
of modern medium and high speed four-cycle engines operating on fuel that contains
corrosive materials such as hydrogen sulphide or halogens (compounds containing chlorine,
fluorine, etc.). These engines are generally of the lean-burn turbo charged design where
increased manifold pressures prevent sufficient lubricant from reaching the valve guide areas
resulting in low oil consumption which can lead to accelerated valve guide and valve
recession. This effect also increases the potential for wear and acid attack of upper cylinder
components from the acidic materials generated during combustion. The Mobil Pegasus 610
is a 1.0% ash, high TBN gas engine oil with exceptional reserve alkalinity designed to offset
the negative effects of these corrosive materials on engine components. The excellent
corrosion protection properties prevent corrosive wear in cylinders, valve areas and bearings
which can result in longer engine life and lower maintenance costs. Mobil Pegasus 610
provides excellent anti-wear and anti-scuff performance assuring minimal piston scuffing,
scoring and cylinder and ring wear. This oil can also be used for the lubrication of the
reciprocating compressors in landfill and biomas gas applications.
Mobil Pegasus 610 is formulated from high quality mineral base oils combined with an
advanced technology 1.0% ash additive system designed to provide excellent protection of
engine and compressor components. This product exhibits a high level of chemical stability
and resistance to oxidation and nitration. Mobil Pegasus 610 offers outstanding resistance to
valve train wear and protection against deposit and sludge formation. These performance
advantages combined with the very effective detergency and dispersancy characteristics
control the formation of ash and carbon deposits that could result in poor engine performance
and detonation.
Features and Benefits
Mobil Pegasus 610 Gas Engine Oil provides an additional margin of protection in those
applications using contaminated fuel. Its excellent detergent / dispersant technology also
results in cleaner engines, lower wear rates and improved engine performance. The use of this
product can result in reduced maintenance costs and improved production capacity. Its
excellent chemical and oxidation stability can result in longer drain periods and reduced filter
costs. The high reserve alkalinity of this product allows its use in engines operating on fuels
with moderate amounts of corrosive materials in the fuel gas.
Features Advantages and Potential Benefits

Controls wear and corrosion when using
contaminated gas
Protects valve seats and faces on four-cycle
engines
Controls combustion chamber ash formation
and improves spark plug performance
Outstanding Anti-wear and Anti-scuff

Mobil Pegasus 801 is an SAE 40 premium performance gas engine oil intended for the
lubrication of all classes of gas engines operating at low, medium and high speeds where low
ash or ashless oils are recommended. It provides outstanding engine cleanliness and
performance by preventing the formation of carbon and ash deposits on pistons, in ring belt
areas, on exhaust and intake ports, on valves and valve stems and in combustion chambers.
Mobil Pegasus 801 also reduces the potential for port carboning of two-cycle gas engines. It
minimizes engine wear and protects valve faces, seats and guides of turbocharged, four-cycle
engines. Mobil Pegasus 801 provides exceptional protection against scuffing in demanding
engine applications and also provides exellent protection against corrosion of internal engine
components. Filter and oil life are extended and the high performance capability of the Mobil
Pegasus 801 can also extend the time between engine maintenance and overhaul periods.

oil formulated from highly refined base oils and an advanced technology additive system. It is
engineered to provide a high level of chemical and thermal stability resulting in cleaner
engines and higher engine performance. Pegasus 801provides exceptional cleanliness and
optimum wear protection in the most severe applications, without the disadvantage of
increased ash deposits.
Features and Benefits
Mobil Pegasus 801 oils provide outstanding performance in both two- and four-cycle gas
engines making it a good choice for all applications where ashless and low-ash oils are
recommended. It's advanced additive system protects high BMEP engines against scuffing,
scoring and wear particularly during critical break-in periods. The result is long engine life
and low maintenance costs. Pegasus 801 has demonstrated outstanding performance over an
exceptionally wide range of engines and operating conditions. Where mixed engines are in

Applications
Mobil Pegasus 801 is intended for the lubrication of the crankcase, power cylinders,
and compressor cylinders of spark-ignited, two- and four-cycle gas engines operating
on clean fuel.
Ideal for engines that drive generators for power production or gas compressors in
gathering, transmission, storage, and distribution of natural gas.
Ebulliently cooled engines
Engines in remote locations which operate virtually unattended for long periods. In
many cases, the engines are operated at, or in excess of full-rated output, while other
applications are intermittent or stand-by service. Reliability, is therefore essential.
Mobil Pegasus 801 oils show excellent results in multipurpose natural gas engine
applications, particularly involving highly turbocharged engines requiring anti-scuff
protection for cylinder liners and piston skirts.
When natural or petroleum gas is being compressed and is dry and free of suspended
liquids or corrosive components, the compressor cylinders usually are lubricated with
the same oil as the engine crankcase. Mobil Pegasus 801has been successful in this
service.
