Marine Engine Oil
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.

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 and excellent DD6V92 TA test results.
The absence of chlorine in Mobilgard™ 450 NC offers easier disposal. Waste-oil disposal costs of chlorine-containing lubricants are generally higher than those without.
