Shell Mysella S3 N is a high performance quality oil blended for use in 4-stroke, spark-ignition engines which require a ‘low ash’ oil and use natural gas as fuel. Shell Mysella S3 N 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.

Shell Mysella S3 S is a high performance quality oil blended for use in 4-stroke, spark-ignition engines which require a ‘medium ash’ oil or use sour gases such as landfill, bio or sewage gas as fuel. Shell Mysella S3 S is also suitable for engines that traditionally require a medium ash oil to protect the valve seating area of the cylinder head. Shell Mysella S3 S 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.

Shell Mysella S5 N is a high performance quality oil blended for use in highly-rated, 4-stroke, spark-ignition engines which require a ‘low ash’ oil. Shell Mysella S5 N 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. Shell Mysella S5 N is specially developed to provide extended drain intervals in those natural gas engines where oil life is a limiting operational factor.
