Mobilgard™ 450 NC marine engine oil

Mobilgard™ 450 NC is a zinc-free, chlorine-free lubricant specifically formulated to meet requirements of heavily loaded diesel engines manufactured by EMD used in marine applications. It is suitable for engines using distillate fuels with sulphur content up to 1.5 per cent.

When used as recommended, Mobilgard 450 NC lubricant may help to:

Protect against sludge formation
Protect critical wear surfaces
Neutralise acids produced in the combustion process
Control carbon deposits and varnish formation, extending oil and filter life
Protect silver bearings
Handle water contamination without additive depletion

Features and Benefits

When used as recommended, Mobilgard 450 NC provides the following features and potential benefits:

Features	Advantages and Potential Benefits
High thermal and oxidation stability	Protects against sludge formation in intermittent marine service providing cleaner, smoother running engines
Effective anti-wear and load carrying properties	Protects critical wear surfaces and extends engine life
High TBN and Outstanding TBN Retention	Controls deposits and neutralizes acids produced in the combustion process
Excellent detergency/dispersancy	Controls carbon deposits and varnish formation which can lead to extended oil and filter life
Zinc-free	Protects silver bearings
Excellent water tolerance and separation	Can handle water contamination without additive depletion

Applications

Mobilgard 450 NC engine oil has been specifically formulated to meet requirements of heavily loaded diesel engines manufactured by EMD and used in marine applications. It is suitable for other high horsepower marine diesel engines, or higher brake mean effective pressure (BMEP) using distillate fuels with a sulfur content up to 1.5 percent. It will lubricate such engines in drilling rigs and stationary power generation service as well. Mobilgard 450 NC has been approved by EMD and is recommended for diesel engines manufactured by Alco, Detroit Diesel (API CF-2) and Fairbanks Morse.

Mobilgard 450 NC engine oil meets the requirements of an SAE 40 grade marine diesel engine oil and is suitable wherever API CF and/or CF-2 performance is specified. It has quality recognition by EMD, excellent DD6V92 TA test results and is rated an LMOA Generation 4 lubricant.

The absence of chlorine in Mobilgard 450 NC offers easier disposal. Waste-oil disposal costs of chlorine-containing lubricants are expected to escalate in the near future.
