Typical characteristics

Manufacturer's description

Medium-ash gas engine oil. Shell Mysella S3 S is a high-performance oil for use in four-stroke, spark-ignition engines that require a "medium ash" oil or that use sour gases, such as landfill, bio or waste gas, as fuel. Shell Mysella S3 S is also suitable for engines that traditionally require a medium-ash oil to protect the valve seat area of the cylinder head. Shell Mysella S3 S meets the needs of the new generation of stationary gas engines designed to comply with emerging legislation limiting NOx emissions, as well as those using the latest "lean" or "clean" burn technology.

Applications

• Spark-ignition gas engines running on natural gas that require a medium-ash oil
• "Dual fuel" gas engines, with pilot diesel fuel ignition
• Ideal for engines running on sour gases

Performance & benefits

• Extended oil lifeSignificantly prolongs oil life by resisting oxidation and nitration; the high TBN (total base number) level neutralises acids and provides corrosion protection, even when "sour" gases are in use.
• Engine protectionShell Mysella S3 S is formulated with an optimised level of "ash" components, which helps extend valve life in engines that prefer an oil with a medium ash level. With a maximum phosphorus content of 300 ppm, Shell Mysella S3 S is compatible with engines fitted with emission catalysts.
