Shell Mysella S3 N 40
Low Ash Stationary Gas Engine Oil
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.
Performance, Features & Benefits
- Extended oil life
Significantly prolongs oil life relative to previous generation gas engine oils by resisting oxidation and nitration, viscosity increase and the formation of harmful acids.
- Engine protection
Shell Mysella S3 N is formulated with low ash and low phosphorus offering extended life to valves and spark plugs and full compatibility with emission catalysts.
Main Applications
- Spark-ignited gas engines fuelled by natural gas
- May also be used for landfill and biogases
