Shell Sirius X 40 - Super High Performance Marine Diesel Engine Oil
Shell Sirius X 40 represents the pinnacle of marine diesel engine lubrication technology, engineered specifically for the most demanding high-speed marine applications. Shell Sirius X is a top quality lubricant, of the Super High Performance Diesel Engine Oil (SHPDO) class, designed for the highest output, high-speed diesel engines, burning distillate fuel.
Advanced SHPDO Technology:
Shell Sirius X 40 utilizes cutting-edge Super High Performance Diesel Engine Oil formulation that is formulated to give better engine protection and longer drain intervals than normal diesel engine oils. This specialized technology addresses the unique challenges of high-speed marine diesel engines operating under extreme conditions.
Superior Bore Polishing Protection:
One of the critical advantages of Shell Sirius X 40 is its exceptional protection against bore polishing. SHPDO type oils are preferred by many engine manufacturers to guard against bore polishing, providing control of blow-by and oil consumption while preserving engine efficiency.
Key Benefits:
- Exceptional Engine Cleanliness - Ability to retain high levels of soot safely in suspension, even with extended drain intervals
- Superior Oxidation Resistance - Oxidation resistance twice that of conventional oils, withstanding high temperatures for longer in severe service
- High Reserve Alkalinity - TBN-E (total base number) of 17 to neutralize acids and provide corrosion protection until the next drain interval, even with higher sulfur levels found in marine distillate fuels
- Maximum Reliability - Free-running piston rings, even under difficult operational conditions, ensuring maximum reliability
- Extended Drain Intervals - Formulated for longer maintenance intervals, reducing operational downtime and costs
- Outstanding Piston Cleanliness - Maintains exceptional cleanliness standards in high-stress marine environments
Specialized Applications:
- High-Speed Marine Engines - Especially suitable for the high power/weight units used in fast vessels and compact generator sets
- Fast Patrol Vessels - Optimized for high-performance military and commercial fast craft
- High-Speed Ferries - Proven performance in demanding passenger transport operations
- Racing Yachts - Premium protection for competitive marine applications
- Offshore Support Vessels - Reliable operation in challenging offshore conditions
- Power Generation - Ideal for marine generator sets requiring maximum efficiency
- High-Output Industrial Engines - MWM Deutz high output, high speed engines and Caterpillar 3600 Series
Technical Specifications:
Shell Sirius X 40 meets API CF specifications and is specifically formulated for distillate fuel applications. Not suitable for North American automotive type engines, for which API CF-4 type oils are required, ensuring specialized performance for marine and industrial high-speed diesel applications.
