Mobil Pegasus™ 1 in a 55 gallon drum 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.
