Mobilgard HSD by Mobil is an extra high performance, multi-grade engine oil specifically formulated for severe service high-speed diesel engines in marine applications. Its advanced chemistry provides outstanding performance in both modern, demanding low-emission diesel engines and older diesel engines operating on low or high sulphur distillate fuel. Mobilgard HSD is approved or recommended by all the major marine high-speed diesel engine builders.Mobilgard HSD combines a blend of high quality base stocks with a superior balanced additive system to provide exceptional control of oil thickening due to soot build-up and high temperatures, as well as outstanding resistance to oxidation, corrosion, and high temperature varnish deposits.

 Features

• Outstanding thermal and oxidation stability
• Reduced deposits in piston under crown and ring belt areas
• Excellent wear properties  
• Extended life of critical engine components
• High Viscosity Index
• Stable oil film at all operating temperatures
• Reduced oil consumption 
• Increased high temp/high shear performance
• Reduced engine scuffing bore polishing and ring sticking
• Outstanding TBN retention
• Protects engine parts from corrosive wear and deposits
• Excellent water tolerance and separation capability
• Maintains effective lubrication and film-strength in the presence of water
• Excellent low temperature properties
• Improved oil pumpability/circulation at start-up
• Start-up wear protection especially for valve train area

Application

Application

• Recommended for use in the latest medium-speed engines designed with "flame-ring" cylinder liners with low lube oil consumption levels operating on high sulphur residual fuels. It 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. This oil is the result of an extensive research and development program, which utilized ExxonMobil's patented RFD (Residual Fuel Detection) Test.
• Mobilgard M460 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.  In these engines, oil life and drain intervals have been significantly reduced when using conventional lower TBN 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 acids resulting from the use of high sulphur fuels.  These acids promote increased lube oil degradation as well as piston ring, cylinder, and bearing corrosion.
• Mobilgard M460 is also recommended for topping-up existing oil charges at marginal TBN values, to raise them to an acceptable value.
