Marine Cylinder Oil | BN 70 | SAE 50
A high-alkalinity, high-viscosity cylinder lubricant engineered for the cylinder lubrication of low-speed, two-stroke crosshead marine diesel engines operating on high-sulphur residual (HSFO) fuels. Formulated with premium base stocks and a robust overbased detergent system for reliable acid neutralisation, deposit control, and liner protection under sustained high thermal and mechanical load.
AEROX MRN MCL 70 is formulated using select virgin base oils blended with a high-BN calcium-based detergent dispersant additive package. The oil is engineered to neutralise corrosive sulphuric acid formed during combustion of high sulphur fuel oils, control piston and ring-belt deposits, and maintain a stable, effective lubricating film on cylinder liners under the extreme pressures and temperatures found in slow-speed crosshead marine engines.
APPLICATIONS
• Cylinder lubrication of low-speed, two-stroke crosshead marine diesel engines (e.g., MAN B&W, WinGD/Sulzer designs) running on high-sulphur residual fuel oil (HSFO up to ~3.5% S).
• Suitable where engine builder / OEM feed-rate guidance calls for a BN 70 cylinder lubricant.
• Compatible with normal oil seal materials used in marine cylinder lubrication systems.
KEY FEATURES & BENEFITS
• High reserve alkalinity (BN 70) for effective, sustained neutralisation of corrosive combustion acids from high sulphur fuels.
• Robust detergency limits piston deposit build-up and ring-belt fouling, supporting steady ring and liner condition.
• Strong oil film strength at elevated liner-wall temperatures reduces scuffing and abnormal wear risk.
• Good demulsibility and filterability supporting clean, reliable feed-rate performance.
• Consistent batch-to-batch quality backed by Aerox Marine’s stringent in-house quality control and certified laboratory testing.
2- AEROX MCL 100
Marine Cylinder Oil | BN 100 | SAE 50
AEROX MRN MCL 100 Marine Cylinder Oil | BN 100 | SAE 50 A high-alkalinity, high-viscosity cylinder lubricant engineered for the cylinder lubrication of low-speed, two-stroke crosshead marine diesel engines operating on medium-to-high sulphur residual fuels. Formulated with premium base stocks and an enhanced overbased detergent system for strong acid neutralisation, deposit control, and liner protection under sustained high thermal and mechanical load.
AEROX MRN MCL 100 is formulated using select virgin base oils blended with an enhanced-BN calcium-based detergent-dispersant additive package. The oil is engineered to neutralise corrosive sulphuric acid formed during combustion of medium-to-high sulphur fuel oils, control piston and ring-belt deposits, and maintain a stable, effective lubricating film on cylinder liners under the extreme pressures and temperatures found in slow-speed crosshead marine engines. Its higher reserve alkalinity makes it well suited to engines where feed-rate optimisation or fuel sulphur levels call for a BN 100 lubricant.
APPLICATIONS
• Cylinder lubrication of low-speed, two-stroke crosshead marine diesel engines (e.g., MAN B&W, WinGD/Sulzer designs) running on medium-to-high sulphur residual fuel oil.
• Suitable where engine builder / OEM feed-rate guidance calls for a BN 100 cylinder lubricant, or where higher reserve alkalinity is desired for operational flexibility across fuel sulphur grades.
• Compatible with normal oil seal materials used in marine cylinder lubrication systems.
KEY FEATURES & BENEFITS
• Enhanced reserve alkalinity (BN 100) for strong, sustained neutralisation of corrosive combustion acids across medium-to-high sulphur fuel grades.
• Robust detergency limits piston deposit build-up and ring-belt fouling, supporting steady ring and liner condition.
▪ Strong oil film strength at elevated liner-wall temperatures reduces scuffing and abnormal wear risk.
