Developed specifically for medium-speed engines
Mobilgard™ M440 is a high performance 40 BN engine oil recommended for use on deep-sea vessels, coastal and river ships operating on
heavy fuel oil (HFO).
This product provides:
Excellent high temperature oxidation
Outstanding residual fuel compatibility
Good thermal stability
High load carrying properties
Outstanding corrosion protection.
Mobilgard M440’s gh alkalinity reserves provide superior protection in neutralising the strong acids resulting from the use of high sulphur fuels,
reducing corrosion and in turn maintenance and repair costs.
Unsurpassed engine cleanliness and protection
Mobilgard M440 oil offers excellent BN retention and resistance to viscosity increase, helping to maximise component life and cleaning intervals
as well as minimise filter changes and purifier maintenance. It also:
Helps protect piston under-crowns from deposits caused by raw fuel dilution
Optimises the life of critical wear surfaces through outstanding anti-wear properties
Minimises oil consumption thanks to low volatility base stocks
