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.

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.
