Mobil Pegasus 605 Ultra 40

Mobil Pegasus™ 605 Ultra 40

Gas Engine Oil

Mobil Pegasus 605 Ultra 40 is formulated primarily to lubricate modern medium-speed and high-speed four-cycle engines operating on landfill and biomass gas. Operations can rely on this outstanding lubricant to help provide:

  • Very long oil life (up to 1,000 hours between drain intervals)
  • Wear, deposit and varnish control
  • Enhanced spark plug performance
  • runtime

    Enhanced engine availability due to very long oil drain intervals and long filter life

  • oil drop

    Exceptional engine cleanliness despite the contaminants common to landfill and biomass gasses

  • gears

    Minimized component wear and scuffing on liners

  • power and energy savings

    Minimized power loss from detonation

Product information

Features and Benefits

•  Exceptional oxidation stability, nitration resistance and thermal stability that help extend oil life, clean engines, reduce filter costs and resist deposit formation

•  Very good anti-wear characteristics help to reduce wear of engine components, reduce scuffing of liners in highly loaded gas engines and provide break-in protection

•  Extraordinary detergent-dispersant system provides protection of upper cylinder and valve train components, clean engines and long filter life

•  Optimized TBN and reserve alkalinity help protect valve seats and faces on four-cycle engines, improve spark plug performance, and reduce power loss from detonation

 

Applications

     •  Engines operating on fuel containing corrosive materials such as THCl (Total Organic Halides as Chloride) such as landfill or biomass gas

     •  Gas engines operating on fuel that contains moderate levels of hydrogen sulfide (H2S)

     •  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

     •  Reciprocating compressors operating on natural gas that contains sulphur or chlorine compounds
