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
-
Enhanced engine availability due to very long oil drain intervals and long filter life
-
Exceptional engine cleanliness despite the contaminants common to landfill and biomass gasses
-
Minimized component wear and scuffing on liners
-
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
