| Mobil Pegasus 905 is an ultra-high performance gas engine oil engineered to meet the most rigorous demands of todays high output, low-emissions, fuel-efficient, four-cycle engines. These gas engines generally operate under high load and high temperature conditions subjecting the lubricant to extreme demands. Mobil Pegasus 905 uses the highest quality base stocks and an advanced additive technology resulting in exceptional oxidation stability, nitration resistance and thermal stability. Mobil Pegasus 905 offers outstanding anti-wear characteristics and protection against valve face and seat recession. Its detergent and dispersant properties reduce the formation of carbon deposits, lacquer and sludge resulting in cleaner engines, longer oil life and reduced filter costs. Its excellent TBN and reserve alkalinity properties protect engine components from acidic materials that are formed during combustion or as the result of degradation. Mobil Pegasus 905 is designed to provide exceptional protection against piston scuffing, scoring and ring and liner wear. It also exhibits excellent resistance to foaming, good demulsibility and high-level corrosion protection. It is formulated with low levels of zinc and phosphorus making it compatible with engines equipped with catalytic converters. Caterpillar, Superior, Waukesha and other turbocharged, naturally aspirated, medium to high speed four-cycle engines requiring a low ash oil; Four-cycle engines experiencing valve face and seat wear; Lean-burn and stoichiometric four-cycle engines operating under high load, high temperature conditions; High-speed four-cycle gas engines used in cogeneration applications; Engines equipped with catalytic converters; Applications using alternate fuels containing low levels of sulfur or chlorine; In field gathering operations where sour gas (low levels of H2S) may be used as fuel |
