Mobilgard 570
Mobilgard 570 is a premium quality marine diesel engine cylinder oil developed for modern two-stroke crosshead engines operating under demanding conditions. The formulation is designed to perform at elevated peak firing pressures and liner temperatures while maintaining strong lubrication film strength. Balanced viscosity and low volatility help ensure effective lubricant distribution and oil film retention across cylinder components.
One of the key advantages of Mobilgard 570 is its excellent cleanliness performance. The oil provides outstanding detergency capability which helps minimise deposits and sludge formation. This supports cleaner piston rings and liners, contributing to improved engine efficiency and reduced maintenance requirements.
Mobilgard 570 also provides strong thermal and oxidation stability. The formulation helps maintain lubricant performance under sustained high-temperature operation while protecting components from corrosive wear. The balanced additive system supports reduced cylinder oil feed rates and improved operating efficiency.
Another important benefit is its suitability for engines operating with moderate sulphur fuel levels. Mobilgard 570 delivers reliable performance in engines operating with fuel sulphur levels down to approximately 1.5%, providing protection while maintaining cleanliness and lubrication. The oil is designed to support consistent performance across varying operating loads.
Mobilgard 570 is recommended for modern marine two-stroke engines requiring reliable lubrication, reduced cylinder oil consumption and strong deposit control. The formulation supports long-term engine protection and consistent performance in demanding marine applications.
Physical characteristics include SAE 50 viscosity grade with kinematic viscosity of approximately 222 mm²/s at 40°C and 20 mm²/s at 100°C. Mobilgard 570 has density of approximately 0.938 kg/m³ at 15°C, flash point of approximately 256°C and pour point of approximately −9°C. Total base number is approximately 70, providing effective acid neutralisation and corrosion protection.
