Mobilgard M50

Mobilgard M50

Mobilgard M50 by ExxonMobil are premium, extra high performance 50 TBN engine oils designed for use in the most severe residual-fuelled medium-speed diesel applications found in marine and stationary power industries. These market leading trunk piston engine oils are formulated utilizing the latest in additive detergent technology and provide outstanding residual fuel compatibility characteristics for excellent engine cleanliness, especially in crankcase, camshaft areas, ring belt and piston undercrowns. They also demonstrate excellent high temperature oxidation and thermal stability, low volatility, and high load carrying properties and corrosion protection.

Advantages and Potential 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.

  1. Excellent thermal and oxidation stability helps reduce deposits in piston undercrown and ring belt areas
  2. Improved anti-wear properties extends the life of critical wear surfaces
  3. Advanced detergency/dispersancy helps clean camshaft and crankcase spaces
  4. Outstanding rust and corrosion properties helps protect wear surfaces from water and acidic corrosion
  5. High Residual Fuel Compatibility reduces sludge formation, longer oil life, cleaner engines
  6. Excellent TBN reserve and retention helps combats fuel/combustion related corrosion and deposits

Applications:

  1. Mobilgard M50 oil can be used in most medium-speed trunk piston engine applications.
  2. Mobilgard M50 is recommended for use in main propulsion and auxiliary engines on deep-sea vessels; in main propulsion engines on coastal and river ships; and in stationary power plants.
  3. Mobilgard M50 oil is designed to meet the needs of engines operating on heavy fuel. It is recommended for use in the latest model medium speed diesel engines and is especially beneficial in engines having low crankcase oil consumption or operating with low cylinder liner temperatures.
  4. 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.
  5. Relatively high alkalinity reserves in this oil provide superior protection in neutralising the strong acids resulting from the use of high sulphur fuels that find access to the crankcase to promote oil degradation and ring, cylinder, and bearing corrosion.
