Typical characteristics

Manufacturer's description

Mobil Pegasus 1100 Series is the latest generation of Mobil Pegasus high-performance gas engine oils, designed to give today's high-output, low-emission four-cycle gas engines the highest levels of protection while maintaining superior performance in earlier model engines. Both Mobil Pegasus 1105 and 1107 exhibit extraordinary oxidation stability, nitration resistance, TBN retention and thermal stability that extend oil life, with formulations balanced for outstanding anti-wear performance and controlled carbon/varnish deposit formation. Mobil Pegasus 1105 (0.5% sulphated ash, SAE 40) helps keep all types of piston engines running longer and cleaner with improved reliability, while Mobil Pegasus 1107 (0.65% sulphated ash, SAE 40) is tailored for high Brake Mean Effective Pressure (BMEP ≥ 22 bar) steel-piston engines, offering excellent alkalinity reserve and retention. Both are recommended for GE Jenbacher, MAN, MTU and other turbocharged or naturally aspirated, medium-to-high-speed four-cycle gas engines, lean-burn and stoichiometric designs under high load/temperature/pressure, high-speed cogeneration engines, natural gas engines with catalytic converters, and field gathering operations using low-H2S sour gas. The series has demonstrated at least 1.5x longer oil drain intervals versus competitive products, and holds an extensive approval list including Caterpillar Energy Solutions TR 2105 (CG132, CG170, CG260), INNIO Jenbacher TI 1000-1108/1109 across multiple engine types and fuel classes, MAN M 3271-2/-5, MWM TR 0199-99-2105, CUMMINS HSK78G, and several Bergen Engines (former Rolls-Royce Bergen) B/C/K-Type gas engine series.

Applications

• GE Jenbacher, MAN, MTU and other turbocharged, naturally aspirated, medium- to high-speed four-stroke gas engines requiring a high-performance lubricant.
• Lean-burn and stoichiometric four-stroke gas engines operating under high-load, high-temperature, high-pressure conditions.
• High-speed four-stroke gas engines used in cogeneration applications.
• Natural-gas-fuelled engines equipped with catalytic converters.
• Field gathering operations where sour gas with low H2S content may be used as fuel.

Performance & benefits

• A long-life gas engine oil that has demonstrated at least 1.5x longer oil-drain intervals versus competing products in high-performance natural-gas-fuelled engines.
• An extraordinary detergent-dispersant system controls the formation of carbon and varnish deposits, minimising oil consumption and maintaining engine cleanliness even during extended drain intervals.
• Exceptional oxidation stability, nitration resistance and thermal stability help extend oil life, reduce filter costs and resist deposit formation.
• Unparalleled anti-wear characteristics help reduce wear of engine components, reduce scuffing of liners in highly loaded gas engines and provide break-in protection.
• Exceptional alkalinity reserve maintains engine performance and durability while extending the oil-drain interval.

Fits
