Shell Argina S5 40
Lubricants for medium-speed trunk piston engines
Shell Argina S5 40 is a multifunctional crankcase lubricant for highly rated medium-speed diesel engines operating on residual fuel. Shell Argina S5 40 has a BN of 55 and is designed for the latest high output and low oil consumption engines.
Performance, Features & Benefits
- Extended oil life
- Engine protection
- System efficiency
Shell Argina S5 40 can be used to top up engines already running on any other member of the Argina family, giving immediate control of BN without the need for an oil change.
Main Applications
Medium-speed industrial or marine propulsion and auxiliary engines, burning residual fuel oils, which create conditions of very high oil stress. These conditions usually occur:
- In newer, high output engine designs and especially DF (duel fuel) engines.
- Where oil consumption is <0.5 g/kWh
- Where load factors are >90%
- Where fuels with sulphur >3% are in use
Note: Due to its high base number 55, this oil has a high ash content. To avoid excessive ash deposits, do not use with low sulphur fuels, or engines with high oil consumption. For these applications other products in the Shell Argina family may be more suitable.
Advice on applications not covered in this leaflet may be obtained from your Shell Representative.
Shell Argina S5 40 is approved by Wartsila and MAN Energy Solutions.
