Manufacturer's description
Low-ash stationary gas engine oil. Shell Mysella S3 N is a high-performance oil for use in four-stroke, spark-ignition engines that require a "low ash" oil and use natural gas as fuel. Shell Mysella S3 N 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
- Spark-ignition gas engines running on natural gas. Can also be used for biogas or landfill gas engines
- Can also be used for biogas or landfill gas engines
Performance & benefits
- Extended oil lifeSignificantly prolongs oil life relative to the previous generation of gas engine oils by resisting oxidation and nitration, viscosity increase and the formation of harmful acids.
- Engine protectionShell Mysella S3 N is formulated with low ash and phosphorus levels, which help extend the life of valves and spark plugs, and offers full compatibility with emission catalysts.
