Mobilgard™ M40 Series extra-high-performance, premium 40 TBN engine oils (Mobilgard™ M340 and Mobilgard™ M440) are designed for use in the most severe, residual-fuelled, medium-speed diesel applications found in marine and stationary power industries.

Formulated using the latest additive detergent technology, Mobilgard M40 Series oils provide the following benefits:

• Reduced deposits in piston undercrown and ring belt areas
• Extends the life of critical wear surfaces
• Clean camshaft and crankcase spaces
• Protects wear surfaces from water and acidic corrosion
• Reduced sludge formation, longer oil life, cleaner engines
• Reduced lubricant consumption
• Combats fuel and combustion related corrosion and deposits

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
Low volatility
High load carrying properties
Outstanding corrosion protection.
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.

Features and Benefits
Mobilgard M440 oil has outstanding 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 excellent lube/fuel compatibility and separates easily from water.
