Feature and Potential Benefits

The state-of-the art technology used in Mobil Pegasus 1 is designed to provide a high level of engine performance in a wide range of high-output gas engines. Its outstanding oxidation resistance and thermal stability provide extended service life for both the engines and the oil. In addition, the unique properties of Pegasus 1 will result in lower internal friction under cold start-up and hot running conditions resulting in reduced wear and potentially lower fuel consumption. The use of this product will result in lower maintenance costs through its extended service life capability, reduced filter costs and improved engine life.

FeaturesAdvantages and potential benefits
Balanced Synthetic FormulationExtended drain intervals and improved engine life, Longer filter life potential, Cleaner engines
Outstanding Oxidation and Thermal StabilityReduced levels of ring land and ring groove carbon, Improved valve guide performance, Lower levels of carbon/coking deposits
Excellent High and Low Temperature PerformanceEffective lubrication under cold startup conditions, Easier engine cranking at low temperatures, Improved engine protection under high temperature conditions
Naturally High Viscosity IndexWide temperature performance
Low VolatilityReduced oil consumption, Reduced deposit formation in critical engine areas
Exceptional Anti-wear and Anti-scuff ProtectionResists wear and scuffing of liners and pistons particularly in high BMEP engines
Low Traction CoefficientPotential for lower fuel costs, Improved engine power, Easier starting


  • Mobil Pegasus 1 is recommended for a wide range of gas engine models.
  • The product is particularly suited for high speed, four-cycle turbocharged and naturally aspirated gas engines requiring a nominal 0.5% ash gas engine oil.
  • It is an excellent lubricant for both stoichiometric and lean-burn designs
  • It is ideally suited for cogeneration and ebullient cooled applications because of its wide temperature range capability and extended engine protection and long oil life.
  • Mobil Pegasus 1 is fully compatible with all seals commonly used in gas engines and with mineral oils but admixture with mineral oils will lower the performance benefits that can be obtained from this outstanding lubricant
  • May be used with gas engines using alternative energy sources for fuel gas containing up to 0.3% sulphur as hydrogen sulphide
