Shell Mysella S5 N 40 – 209L

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 sour
gas. 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 sour gases. Thanks to its low ash content, Shell Mysella S5 S
minimizes the contribution of the lubricating oil to combustion chamber deposit.

Good resistance to oxidation and nitration, and
the strong base additives in its formulation,

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.

Good anti-wear properties and offers
superior control of oil related deposits.

A low ash oil, the contribution of oil ash to combustion chamber deposits will be minimized.

Compatible with engines equipped with exhaust emission catalysts for CO, NOx and formaldehyde.
