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.
