Shell Mysella Oil MA


Shell Mysella Oil MA is a Premium quality stationary gas engine oil

Shell Mysella Oil MA is a premium quality oil blended for use in highly-rated spark ignition and dual-fuel four-stroke engines which require a ‘medium ash’ oil, or where “sour gas” is in use. It satisfies the new generation of stationary gas engines designed to meet the emerging legislation limiting emissions of NOx, and those which employ the latest ‘lean’ or ‘clean’ burn technology




Spark-ignited gas engines fuelled by natural or so called sour gas


Mysella MA is developed for engines and applications requiring a “medium ash” oil. It is suitable for use with all types of gases; natural (sweet) gas as well as so called sour gases like landfill and sewage gas.


“Dual-fuel” gas engines ignited by diesel pilot fuel


Performance Features and Benefits


Excellent piston & engine cleanliness
  • Long and efficient engine operation.


Enhanced diesel detergency for dual-fuel engines

  • Keeps engines using diesel fuel clean.


Very high oxidation & nitration resistance
  • Prolongs oil life by resisting viscosity increase and the formation of harmful acids, especially in demanding cogeneration (CHP) applications.


Optimised level of ‘ash’ components
  • Helps prolong the life of valves, in engines which prefer a medium ash oil.


Reserve alkalinity
  • The high level of TBN (total base number) neutralises acids and provides corrosion protection, even when “sour” gases are in use.


Low phosphorus level
  • With a maximum phosphorus content of 300 ppm Mysella MA is compatible with engines equipped with emission catalysts.
