Mobilgard 412
Mobilgard 412 is a high-performance diesel engine oils developed for trunk piston engines operating on low sulphur distillate fuels in marine and industrial applications. These oils are formulated to provide excellent oxidation resistance, viscosity control and strong corrosion protection over extended service intervals.
One of the key advantages of Mobilgard 412 is its excellent thermal and oxidation stability. The formulation resists oil degradation and viscosity increase, allowing longer operating intervals between inspections and maintenance. This helps improve reliability and reduce operating costs in marine and industrial diesel engines.
Mobilgard 412 also provides strong anti-wear protection and detergency performance. The balanced additive system helps reduce ring and liner wear while maintaining engine cleanliness. This helps prevent deposit formation, extend component life and support consistent engine performance.
Another important benefit is its excellent water separation and corrosion protection. Mobilgard 412 protects against corrosive wear and maintains effective lubrication even in the presence of moisture contamination. The oil also provides strong TBN retention, supporting extended oil life and improved engine protection.
Mobilgard 412 is intended for use as cylinder and bearing lubricant in marine and industrial diesel engines operating on distillate fuels or light fuel blends. It is particularly effective in high-speed engines, severe service engines and many medium-speed diesel engines. It may also be used as crankcase lubricant in large crosshead diesel engines operating on high sulphur fuels.
Physical characteristics include SAE 40 viscosity grade with kinematic viscosity of approximately 142 mm²/s at 40°C and 14.5 mm²/s at 100°C. Mobilgard 412 has density of approximately 0.899, flash point of approximately 272°C and pour point of approximately −9°C. Total base number is approximately 15, providing protection against corrosive wear and extended service life.
