Manufacturer's description

Mobilgard M50 is a premium, extra high performance 50 TBN engine oil designed for the most severe residual-fuelled medium-speed diesel applications in marine and stationary power industries. Formulated with the latest additive detergent technology, this market-leading trunk piston engine oil provides outstanding residual fuel compatibility for excellent engine cleanliness, especially in the crankcase, camshaft areas, ring belt and piston undercrowns, along with excellent high-temperature oxidation and thermal stability, low volatility, high load-carrying properties and corrosion protection. Mobilgard M50 suits most medium-speed trunk piston engine applications, including main propulsion and auxiliary engines on deep-sea vessels, main propulsion engines on coastal and river ships, and stationary power plants, and was developed using ExxonMobil's patented DAC (Detecting Asphaltene Contamination) Test. It is especially beneficial in engines with low crankcase oil consumption or low cylinder liner temperatures, where conventional lube oils have suffered reduced oil life and drain intervals from severe TBN depletion; its relatively high alkalinity reserves neutralise the strong acids from high sulphur fuels, and the product is also recommended for topping up existing oil charges with low TBN to raise them to an acceptable value. Mobilgard M50 has industry-leading thermal and oxidation stability, excellent TBN retention and resistance to viscosity increase over long operating periods, a high level of engine cleanliness and wear protection, and superior lube/fuel compatibility with easy separation from water.

Applications

• Mobilgard M50 oil can be used in most medium-speed trunk-piston engine applications.
• It is recommended for main-propulsion and auxiliary engines on deep-sea vessels, main-propulsion engines on coastal and river ships, and stationary power plants.
• This oil is the result of an extensive research and development programme, incorporating ExxonMobil's patented DAC (Detecting Asphaltene Contamination) test.
• Mobilgard M50 oil is designed to meet the needs of engines operating on heavy fuel.
• It is recommended for the latest model medium-speed diesel engines and is especially beneficial in engines with low crankcase oil consumption or operating at low cylinder-liner temperatures.
• In these engines, oil life and drain intervals have been significantly reduced when using conventional lube oils, due to severe TBN depletion resulting from very low lube-oil consumption.
• Relatively high alkalinity reserves in this oil provide superior protection in neutralising the strong acids resulting from the use of high-sulphur fuels that reach the crankcase and promote oil degradation and ring, cylinder and bearing corrosion.
• Mobilgard M50 is also recommended for topping up existing oil charges with a low TBN value, to raise them to an acceptable value.

Performance & benefits

• Mobilgard M50 has industry-leading thermal and oxidation stability.
• It has excellent TBN retention and resistance to viscosity increases over long operating periods.
• It also promotes a high level of engine cleanliness with protection against wear.
• Compared to other medium-speed engine oils, it has superior lube/fuel compatibility and separates easily from water.
• Excellent thermal and oxidation stability: reduced deposits in the piston undercrown and ring-belt areas.
• Improved anti-wear properties: extends the life of critical wear surfaces.
• Advanced detergency/dispersancy: clean camshaft and crankcase spaces.
• Outstanding rust and corrosion properties: protects wear surfaces from water and acidic corrosion.
• High residual-fuel compatibility: reduced sludge formation, longer oil life, cleaner engines.
• Low-volatility base stocks: reduced lubricant consumption.
• Excellent TBN reserve and retention: combats fuel/combustion-related corrosion and deposits.
