Specifications and Approvals
Shell Argina S enjoys a comprehensive range of Original Equipment Manufacturers’ approvals through field experience over many years and meets the engine test criteria for API CF .
Applications
Shell Argina S is a multifunctional crankcase lubricant for certain medium-speed diesel engines operating on residual, blended or distillate fuels.
For use in:
Medium-speed industrial or marine propulsion and auxiliary engines, burning residualor blended fuel oils, which create conditions of low oil stress. These conditions usually occur:
- in engine designs more than 5 years old,
- where oil consumption is 1.5g/kWh or more,
- where load factors are below 70%, or
- where fuels with sulphur <2% are in use
-
some medium and high speed engines burning distillate fuel, where a high BN, high ash lubricant is suitable
Marine engine reduction gears and certain other ship-board applications, where specialist lubricants are not required.
Argina S is not recommended for engines where an API CF-4, CG-4, CH-4 or CI-4 oil is required.
