Dầu Shell Sirius X

Shell Sirius X is a Super High Performance Diesel Engine Oil

Shell Sirius X is a top quality lubricant, of the Super High  Performance Diesel Engine Oil (SHPDO) class. It is designed for the highest output, high-speed diesel engines, burning distillate fuel and is formulated to give better engine protection and longer drain intervals than normal diesel engine oils.

Shell Sirius X is especially suitable for the high power/weight units used in fast vessels and compact generator sets.

Applications

• High-speed diesel engines operating on distillate fuels
• N.B. Not suitable for N. American automotive type engines, for which API CF-4 type oils are required.

Performance Features

Outstanding piston cleanliness

• Free-running piston rings, even under difficult operational conditions, ensuring maximum reliability.

Exceptional protection against bore polishing

• Control of blow-by and oil consumption, preserving engine efficiency. SHPDO type oils are preferred by many engine manufacturers to guard against bore polishing.

Exceptional engine cleanliness

• Ability to retain high levels of soot safely in suspension, even with extended drain intervals.

Oxidation resistance twice that of conventional oils

• Ability to withstand high temperatures for longer, in severe service or with extended drain intervals.

High reserve alkalinity

• A TBN-E (total base number) of 17 to neutralise acids and provide corrosion protection until the next drain interval, even with the higher sulphur levels sometimes found in marine distillate fuels.
