ARGINA S4 X 40

ARGINA S4 X 40

Shell Argina S4 X 40 is a high-performance crankcase lubricant specifically formulated for medium-speed diesel engines operating on residual fuel. With a base number (BN) of 40, it is designed to withstand high oil stress conditions, making it ideal for modern engine designs, especially those less than 10 years old and equipped with flame rings. This lubricant is particularly effective in engines consuming oil between 0.5 to 1 gram per kilowatt-hour and operating with fuels containing over 2% sulfur.
