Shell Argina X 40
ShellArgina X 40 is a high-quality lubricant with all the excellent performance characteristics of Argina T, but with a higher alkaline value. The oil is designed for medium-speed power plants operating on residual fuels when low oil consumption and/or high sulfur levels in fuels require additional alkalinity. This is necessary to maintain the equilibrium level of the alkaline number prescribed by the engine manufacturer in order to limit the wear of the cylinder liner and piston rings.
Purpose: for medium-speed marine engines operating on residual fuel
