About Mobil Pegasus 1

Mobil Pegasus 1 is a high performance synthetic gas engine oil, designed to meet the highest performance requirements. It is engineered for the most demanding naturally aspirated and turbocharged stoichiometric and lean-burn stationary gas engines. The unique formulation of Mobil Pegasus 1 minimises ash deposits, piston land and ring belt deposits, liner scuffing as well as valve seat and valve face wear. It also provides outstanding resistance to oxidation. The inherently high viscosity index of the synthetic oil components ensures a protective lubricant film at high temperatures, well above the limit for mineral oil-based products.

Advantages and Potential Benefits:

• Extended lubricant drain intervals reduces maintenance costs
• Reduced formation of sludge and deposits in critical engine areas improves engine life
• Increased operating capacity, even at high temperatures
• Reliable flow and lubrication for easy startup, even at low temperatures
• Excellent protection against wear and scuffing of liners and pistons, particularly in high BMEP engines, reduces maintenance costs
• Fully compatible with seals commonly used in gas engines and with mineral oils; mixture with mineral oils will lower the performance benefits that can be obtained from this outstanding lubricant

Applications:

• Wide range of gas engine models
• High speed, four-cycle turbocharged and naturally aspirated gas engines requiring a nominal 0.5% ash gas engine oil
• Stoichiometric and lean-burn designs
• Ebulliently cooled applications because of its wide temperature range capability, extended engine protection and long oil life

About Mobil Pegasus 1005

About Mobil Pegasus 610

Mobil Pegasus™ 610 is a high performance natural 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 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. Mobil Pegasus 610 is a 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 help to prevent 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 biomass gas applications.

Mobil Pegasus 610 is formulated from high quality mineral base oils combined with an advanced technology 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 induced pre-ignition.

Advantages and Potential Benefits:

1. Extended lubricant drain intervals reduces maintenance costs
2. Extended catalytic converter service intervals reduces maintenance costs
3. Excellent protection against corrosion by contaminated gas
4. Reduced formation of combustion chamber ash
5. Improved spark plug performance
6. Optimum operating efficiency

Applications:

1. Gas engines operating on fuel that contains moderate level of hydrogen sulphide
2. Engines operating on fuel containing corrosive components such as TOHCI (Total Organic Halides such as Chloride)such as landfill or biomass gas
3. Spark ignited four cycle gas engines with very low oil consumption
4. Reciprocating compressors operating on natural gas that contains sulphur or chlorine compounds
5. High output or naturally aspirated engines operating at, or in excess of, rated capacity under high temperatures

About Mobil Pegasus 710

Mobil Pegasus™ 710 is a premium performance gas engine oil primarily intended for the lubrication of modern high-speed four-cycle engines where oil consumption is very low. These engines are generally of the lean-burn design where increased manifold pressures prevent sufficient lubricant from getting into the valve guide areas. This oil is also recommended for the lubrication of gas compressors. It is formulated from high quality mineral base oils and an advanced medium ash additive system designed to provide excellent protection of engine and compressor components. It exhibits a high level of chemical stability and resistance to oxidation and nitration. Pegasus 710 offers outstanding resistance to valve train wear and protection against deposit formation. These performance advantages combined with its very effective detergency and dispersancy system control the formation of ash and carbon deposits that could result in poor engine performance and detonation.

Its high reserve alkalinity and TBN retention also makes it suitable for engines operating on fuels that contain low amounts of corrosive materials such as hydrogen sulphide. The excellent anti-corrosion properties prevent corrosive wear in cylinders, valve areas and bearings resulting in longer engine life. Mobil Pegasus 710 anti-wear and anti-scuff performance assures minimal piston scuffing, scoring and cylinder and ring wear.

Advantages and Potential Benefits:

1. Low wear of engine components, reduced scuffing of liners of highly loaded gas engines. Providing excellent break-in protection
