Shell Mysella S5 N is a high performance quality oil blended for use in highly-rated, four- 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.
Extended oil life
Thanks to its good resistance to oxidation and nitration, and the strong base additives in its formulation, Shell Mysella S5 S will provide an extended oil life in comparison to standard gas engine oils.
Note that oil life will be dEPendent on the level of contaminants in the gas.
Engine protection
Shell Mysella S5 S has good anti-wear properties and offers superior control of oil related dEPosits. Qualified as a low ash oil, the contribution of oil ash to combustion chamber dEPosits will be minimized.
Shell Mysella S5 S is compatible with engines equipped with exhaust emission catalysts for CO, NOx and formaldehyde.
System efficiency
In engines utilising crank case gas recirculation Shell Mysella S5 S is expected to reduce fouling and clogging of charge air coolers.
