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

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
