It is a multifunctional crankcase lubricant for highly rated medium-speed diesel engines operating on residual fuel. It is is designed for conditions of moderate oil stress. Medium-speed engines burning residual fuel need very specialised lubricants. Heavy fuels contaminate the oil with asphaltenes, requiring special types of detergency to avoid sludges. The combustion of high sulphur fuels produces sulphur acids, which cause high wear rates of piston rings and cylinder liners unless neutralised by a high basicity reserve in the oil. The oil is in service for very long periods, so centrifugal separators are used to remove water and combustion contaminants from the oil. Medium-speed engine oils must be specially designed to release these contaminants in the separator.
Features / Benefits:
· Engine cleanliness.
· Rapid neutralisation of acidic combustion products. · Thermal stability and resistance to oxidation.
· Suitability for centrifugal separators.
