Mobil Pegasus™ 1, 5 gallon pail, is an SAE 15W40 synthetic gas engine oil designed to improve engine and oil life, reduce maintenance costs, and lower fuel costs in a wide range of high-output gas engines.

Features and Benefits

  • Balanced Synthetic Formulation - Extended drain intervals and improved engine life, longer filter life potential, and cleaner engines.
  • Outstanding Oxidation and Thermal Stability - Reduced levels of ring land and ring groove carbon, improved valve guide performance, and lower levels of carbon/coking deposits.
  • Excellent High and Low Temperature Performance - Effective lubrication under cold startup conditions, easier engine cranking at low temperatures, and improved engine protection under high temperature conditions.
  • Naturally High Viscosity Index - Wide temperature performance.
  • Low Volatility - Reduced oil consumption and reduced deposit formation in critical engine areas.
  • Excellent Anti-Wear and Anti-Scuff Protection - Resists wear and scuffing of liners and pistons, particularly in high BMEP engines.
  • Low Traction Coefficient - Potential for lower fuel costs, improved engine power, and easier starting.


  • Gas engine models requiring a nominal 0.5% ash gas engine oil.
  • High-speed, four-cycle turbocharged gas engines.
  • Naturally aspirated gas engines.
  • Gas engines using alternative energy sources for fuel gas containing up to 0.3% sulfur as hydrogen sulfide.
  • Excellent lubricant for stoichiometric and lean-burn designs.
  • Cogeneration and ebullient cooled applications (due to wide temperature range capabilities).
  • Compatible with all seals commonly used in gas engines and with minerals oils but admixture with mineral oils will lower performance benefits.
