Mobilgard 1 SHC
Mobilgard 1 SHC is a supreme performance synthetic diesel engine oil specifically formulated for high power, distillate-fuelled diesel engines operating in severe marine applications. The advanced synthetic formulation provides excellent lubrication, long drain capability and extended engine life in demanding operating conditions. The oil is engineered to perform across a wide temperature range while maintaining strong film strength and wear protection.
One of the key advantages of Mobilgard 1 SHC is its outstanding temperature performance. Although a true SAE 40 grade, the oil provides stronger lubrication film strength on hot engine parts than many SAE 50 oils. At low temperatures it flows like an SAE 20W product, delivering excellent start-up protection and reliable lubrication at temperatures as low as −54°C.
Mobilgard 1 SHC also provides exceptional thermal and oxidation stability. The formulation helps minimise high temperature deposits, sludge and varnish formation, supporting cleaner engines and extended oil drain intervals. Low volatility reduces oil consumption while enhanced anti-wear protection helps extend the life of critical engine components.
Another important benefit is its wide application capability. Mobilgard 1 SHC is recommended as a crankcase lubricant for medium and high-speed diesel engines in severe marine service. It is suitable for high power density engines, applications with frequent start-up and shutdown cycles, and operations exposed to extreme temperatures. The oil is also suitable for marine gearing applications requiring FZG Level 12 performance and is compatible with conventional mineral oils.
Mobilgard 1 SHC can be used in military patrol vessels, high-speed ferries, rescue boats, auxiliary engines and emergency generators. The zinc-free formulation allows use in engines containing silver bearing components while helping reduce environmental impact and waste oil generation.
Physical characteristics include SAE 40 viscosity grade with kinematic viscosity of approximately 109 mm²/s at 40°C and 14.5 mm²/s at 100°C. Mobilgard 1 SHC has density of approximately 0.872 kg/L at 15°C, flash point of approximately 250°C and pour point of approximately −54°C. Total base number is approximately 15, supporting long drain capability and strong engine protection.
