Mobilgard M20 Series
ExxonMobil marine , Pacific Islands
Product Description
Mobilgard M20 Series by ExxonMobil is a premium, extra high performance 20 TBN engine oil series designed for use in the residual, distillate and LNG-fuelled medium-speed diesel engine applications found in marine and stationary power industries.
Mobilgard M20 Series is an extension to the outstanding ExxonMobil Mobilgard M Series trunk piston engine oils and is specifically formulated to support the transition to lower Sulphur fuels in light of fuel regulations.
High performance additive detergent technology is utilised to provide outstanding residual fuel-lube compatibility characteristics for enhanced engine cleanliness, especially in crankcase compartments, camshaft areas, piston ring and under-crown areas.
Mobilgard M20 series oils also demonstrate excellent high temperature oxidation and thermal stability, low volatility, high load carrying properties and corrosion protection across a wide range of fuel grades.

Applications
Mobilgard M20 Series oils can be used in most medium-speed trunk piston engine applications. They are 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. This new Series of oils is the result of an extensive research and development program, incorporating ExxonMobil's patented DAC (Detecting Aspahltene Contamination) Test.
Mobilgard M20 Series is specifically formulated for use in medium speed engines using 0.50% and 0.10% sulphur fuels and liquefied natural gas (LNG) due to its low BN formulation. They are recommended for use in the latest model medium speed diesel engines and are especially beneficial in engines having low crankcase oil consumption or operating with low cylinder liner temperatures.
