Key Features and Benefits:

Extended Oil Life: The high BN 40 formulation enhances oxidation resistance, reducing the frequency of oil changes and extending oil life.
Engine Protection: With superior detergency, Shell Argina S4 40 ensures exceptional cleanliness of crankcases, valve decks, and pistons, effectively minimizing deposits in critical areas such as under-piston crowns.
System Efficiency: The oil’s formulation effectively separates contaminants and water in centrifugal separators, maintaining optimal system performance.

Primary Applications:

Lubrication of medium-speed industrial or marine engines and auxiliary engines operating on residual fuels with high sulfur content, typically above 2%.
Suitable for engines with oil consumption ranging from 0.5 to 1 gram per kilowatt-hour.
Applicable in marine gearboxes and other equipment not requiring specialized lubricants.
