  • 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. 


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.

Note : Engines operating on fuel gas with elevated levels of sulphur or chlorine compounds should also have coolant (jacket water) and oil temperatures raised.

  • 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
