Product Description
Mobil Pegasus™ 805 Ultra is a high performance gas engine oil engineered to meet the rigorous demands of today's high output four-cycle engines designed to reduce emissions and improve fuel-efficiency. It meets a wide range of OEM requirements making it a great choice where high-speed four-cycle engines from various OEMs are used.
Mobil Pegasus 805 Ultra is designed to provide very good 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.
Features and Benefits
• Extraordinary oxidation stability and nitration resistance provide cleaner engines, good oil life, and reduced oil disposal and filter costs
• Very good anti-wear characteristics help to reduce wear of engine components and reduce scuffing of pistons and liners
• Good corrosion resistance protects bearings and internal components
• Extraordinary detergent-dispersant system provides protection of valve train components, cleaner engines and longer filter and spark plug life
• Very good foam separation reduces potential negative effects of air on wear and oil degradation
Applications
• Caterpillar, 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 Sulphur or Chlorine
• In field gathering operations where sour gas (low levels of H2S) may be used as fuel
