Performance, Features & Benefits of Shell Mysella S5 S 40

+ 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.
