Mysella S5 S (LNG sergias biogas sewage gas landfill gas)

Shell Mysella S5 S 40 was specially developed to allow long oil change intervals and to protect engines optimally. Due to its special shape it offers special protection against corrosion and oxidation, which can be caused by sulphur and halogen acid content in acid gases. Due to the low ash content it helps to minimize the formation of deposits in the combustion chamber.

Gas engines

Ideal for use in four-stroke gas engines used for power generation and CHP (combined heat and power) plants, especially when burning biogas, sewage gas or landfill gas.

Extended oil life

Thanks to its high oxidation and nitration resistance and the use of special additives, Shell Mysella S5 S offers a much longer oil life than a standard gas engine oil. Please note that the oil life varies depending on the amount of contaminants in the gas.

-Engine protection

Shell Mysella S5 S offers very good wear protection properties and reliably prevents the formation of oil-related residues. It is classified as a low ash oil and helps to minimize deposits in the combustion chamber. It is suitable for use in engines equipped with exhaust catalysts for carbon monoxide, NOx and formaldehyde.

-Engine efficiency

Shell Mysella S5 S helps to minimize contamination and blockages of the charge air coolers of engines with gas recirculation from the crankcase.

Specifications, approvals and recommendations

Shell Mysella S5 S is suitable for gas engines that require low-ash oil.
