Performance benefits
1. Engine Protection
Designed to keep pistons clean at moderate BN and oil ash level, eliminating the need to alternate with cylinder oils of higher and lower BN to help maintain cleanliness.
Anti- seizure properties help minimize the risk of scuffing and increase thermal stability to minimize the deposit build up. Formulated to prevent ring sticking.
Designed to help protect against corrosive wear for a range of low and zero sulphur fuels including VLSFO, ULSFO, LNG and methanol.
2. Engine Exhaust Cleanliness
Operation with a lower sulfated ash lubricant can help reduce accumulation of oil ash in scavenge space, on exhaust valves, turbocharger and other components in the exhaust system such as economizer and critical exhaust gas after treatment systems as SCR, EGR, DPF.
3. StorageStability
Stable at ambient temperatures and during long-term storage.
4. Compatibility
Miscible and compatible with diesel cylinder lubricants commonly used in the international marine trade.
