Mobil Pegasus 805
Gas Engine Oil
Product Description
Mobil Pegasus 805 is premium 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. These gas engines generally operate under high load and high
temperature conditions. Mobil Pegasus 805 is made from high quality base stocks and an advanced technology additive system that
provides exceptional oxidation stability, nitration resistance and thermal stability. Its detergent and dispersant system controls the
formation of carbon deposits, lacquer and sludge resulting in cleaner engines, longer oil life and reduced filter costs.
Mobil Pegasus 805 is also designed to provide exceptional protection against piston scuffing, scoring and ring and liner wear. It exhibits
excellent resistance to foaming, good demulsibility and protection against corrosion. It is formulated with very low levels of zinc and
phosphorus making it compatible with engines equipped with catalytic converters.
Features and Benefits
Mobil Pegasus 805 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.
