Gas Engine Oils

Product Description

Mobil Pegasus 1

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 stationary 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. The product will flow at -54º C ensuring good cold startup properties and effective lubrication at cold temperatures. Mobil Pegasus 1 exhibits low volatility, a performance a 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.

 

Applications

  • Mobil Pegasus 1 is recommended for a wide range of gas engine models.
  • The product is particularly suited for high speed, four-cycle turbocharged and naturally aspirated  gas engines requiring a nominal 0.5% ash gas engine oil.
  • It is an excellent lubricant for both stoichiometric and lean-burn designs
  • It is ideally suited for cogeneration and ebullient cooled applications because of its wide temperature range capability and extended engine protection and long oil life.
  • Mobil Pegasus 1 is fully compatible with all seals commonly used in gas engines and with mineral oils, but admixture with mineral oils will lower the performance benefits that can be obtained from this outstanding lubricant
  • May be used with gas engines using alternative energy sources for fuel gas containing up to 0.3% sulphur as hydrogen sulphide

Mobil Pegasus 605

Mobil Pegasus 605 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 valve guide wear and valve recession. This effect also increases the potential for wear and acid attack of upper cylinder components from the corrosive materials generated during combustion. The Mobil Pegasus 605 is a 0.5% ash gas engine oil with exceptional reserve alkalinity designed to offset the negative effects of acidic materials on engine components. The excellent corrosion protection properties helps prevent corrosive wear in cylinders, valve areas and bearings which can result in longer engine life and lower maintenance costs. Mobil Pegasus 605 provides excellent anti-wear and anti-scuff performance which helps assure minimal piston scuffing, scoring and low cylinder liner and piston ring wear. Mobil Pegasus 605 also exhibits excellent deposit control and prevents siloxane deposits and liner laquering in bio-fuel and landfill gas applications with high silicon content. The prevention of these deposits is key to maintaining effective control of lube oil consumption. This oil can be used for the lubrication of the reciprocating compressors in landfill, mine, coal seam, digester/fermenter, sewage and other biomass gas applications that operate in a wide range of municipal, industrial, cooperative and farm applications (i.e. electric power generation, boiler heating, cogeneration/combined heat and power, etc).

Mobil Pegasus 605 is formulated from high quality mineral base oils combined with an advanced technology, low 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. Pegasus 605 offers outstanding resistance to valve train wear and protection against deposit formation. These performance advantages combined with the very effective detergency and dispersancy characteristics helps control the formation of ash and carbon deposits that could result in poor engine performance and detonation. This product also compatible for use in gas engines equipped with catalytic converters.

 

Applications

  • Gas engines operating on fuel that contains moderate levels of hydrogen sulphide (H2S)
  • Engines operating on fuel containing other corrosive materials such as TOHCl (Total Organic Halides as Chloride) such as landfill or biomass gas
  • Spark ignited four-cycle gas engines with very low lube oil consumption
  • Medium and high speed four-cycle engines equipped with catalytic converters requiring a low ash gas engine oil
  • Engines experiencing valve train wear and corrosion
  • Reciprocating compressors operating on natural gas that contains sulphur or chlorine compounds
  • High output or naturally aspirated engines operating at or in excess of rated capacity under high temperatures

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. 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.

 

Applications

  • Gas engines operating on fuel that contains moderate levels of hydrogen sulphide (H2S)
  • Engines operating on fuel containing other corrosive components such as TOHCl (Total Organic Halides as Chloride)
  • Spark ignited four-stroke cycle gas engines with very low oil consumption
  • Reciprocating compressors operating on natural gas that contains sulphur or halogens
  • High output or naturally aspirated engines operating at or in excess of rated capacity under high temperatures
