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 exceptionally good water separating ability.

Features and Benefits

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

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 marine diesel engines of the highest horsepower, 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.
