Long Life, Low Ash Gas Engine Oil
- Shell Mysella S5 S is a premium gas engine oil, formulated for use in engines burning non-natural “sour” gas, such as biogas, sewage gas and landfill gas.
- Shell Mysella S5 S has been specially developed to provide extended oil drain intervals in engines running on biogas, sewage gas and landfill gases. Shell Mysella S5 S uses a formulation which has been optimised to resist the corrosive and oxidative effects of sulphuric and halogenic acids which are often present in these gases.
- Thanks to its low ash content, Shell Mysella S5 S minimizes the contribution of the lubricating oil to combustion chamber deposits.
Performance, Features & Benefits:
- 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.
Main Applications:
- Gas Engines - All types of 4-stroke gas engines burning biogas, sewage gas or landfill gas.
