Mobil industrial , United States
Gas Engine Oil
Product Description
Mobil Pegasus 805 Super is a premium performance gas engine oil developed to meet the rigorous demands of today's high output four-cycle engines which have been designed to reduce emissions and improve fuel-efficiency. These gas engines generally operate under high load and high temperature conditions and are subjected to a wide range of startup temperatures. Its high viscosity index and low temperature properties provide excellent cold start performance as well as exceptional high temperature lubrication characteristics. The use of the high quality mineral oil base stocks and an advanced low-ash additive technology provides exceptional oxidation stability, nitration resistance and thermal stability. It is a low ash formulation that exhibits medium ash performance characteristics. Mobil Pegasus 805 Super, therefore, offers outstanding valve face, seat and guide protection. Its detergent and dispersant performance controls the formation of carbon deposits, lacquer and sludge resulting in cleaner engines, longer oil life; and reduced filter costs.
Mobil Pegasus 805 Super 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 protection against corrosion. It is formulated with very low levels of zinc and phosphorus making it compatible with engines requiring low ash oils and equipped with catalytic converters.
Features and Benefits
Mobil Pegasus 805 Super is designed to provide optimum engine life and low maintenance costs. It is an excellent choice where high-speed four-cycle engines from various OEMs can be used. Its 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.
