Description:

Shell Sirius FB Oils are premium quality marine diesel engine oils for use in mediumspeed trunk-piston engines operating on distillate fuels. They are specially designed to control oil consumption, in modern highly rated distillate fuelled diesel engines where liner lacquering can be a problem. 

Applications:

Highly rated medium-speed diesel engines operating on distillate fuels, especially :

• in high load or overload operation (e.g. fishing trawlers)
• where low sulphur (< 0.5% wt.) fuels are in use 

Performancce Features:

Shell Sirius FB has been formulated to provide:

• Reduced levels of liner lacquer, thereby maintaining lubricating oil consumption at its normal level. Unlike many other oils used to control liner lacquer, this is achieved without compromising other aspects of performance in any way.
• A high level of protection against bore polishing, which is another cause of high oil consumption.
• Excellent piston and crankcase cleanliness.
• Ability to release water and contaminants in centrifugal separators.
• Load carrying properties required for use in reduction gears.
• API performance level CD.
