Engine oils

Shell offers a complete range of lubricating oils for marine engines burning gas, heavy fuel, gas oil or liquid biofuel. All of Shell’s engine oils are designed to minimise deposit build-up and to help keep your engine clean. Some of our products include Shell Argina, specifically formulated for four-stroke diesel engines, to keep piston under crowns clean, maintaining cooling performance and preventing hot corrosion. For gas engines, Shell Mysella provides superior deposit control, even in engines with high piston temperatures. This maintains excellent ring belt cleanliness and cylinder liner protection. Shell Alexia is a cylinder oil for use in all 2-stroke low-speed diesel engines.
