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.


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.

Mobil Pegasus 801

Gas Engine Oil

Product Description

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.

The Mobil Pegasus 801 is the latest generation of ashless detergent and anti-scuff gas engine

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.


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

service Mobil Pegasus 801 provides a single product which simplifies inventory and reduces

the potential for product misapplication.

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.
