Mobilgard™ 450 NC

Diesel Engine Oil

Product Description

Mobilgard™ 450 NC (No Chlorine) engine oil by ExxonMobil is a non-zinc ａnd non-chlorine lubricant formulated with high-quality basestocks which provide low consumption characteristics, high-temperature oxidation resistance, ａnd thermal stability.  These basestocks are combined with specially selected stable additives resulting in an engine oil with well-balanced properties.

The detergent/dispersant qualities of Mobilgard 450 NC increases filter life ａnd engine cleanliness.  Its sustained high alkalinity provides excellent corrosion protection when using fuels containing up to 1.5 percent sulfur even though metals such as steel, copper, silver ａnd bronze are present.  Mobilgard 450 NC has outstanding lubricating properties ａnd provides the necessary protection against corrosion.

Mobilgard 450 NC exhibits superior quality in reduced wear in piston rings ａnd cylinder liners.  It possesses good water separating ability.

 

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.
