Mobil Pegasus 905
Gas Engine Oil
Product Description
Mobil Pegasus 905 is an ultra-high performance gas engine oil engineered to meet the most rigorous demands of today's 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.
Features and Benefits
Mobil Pegasus 905 is designed to provide optimum engine life and low maintenance costs. It meets a wide range of OEM requirements making it an excellent choice where high-speed four-cycle engines from various OEMs are used. Its unique innovative technology allows for control of valve train component wear and reduces the potential for scuffing, scoring and accelerated piston and ring wear. The end result is lower costs of operating and maintaining your gas engines.
