Mobilgard 409 NC
Marine Crankcase Oil
Product Description
Mobilgard 409 NC (No Chlorine) engine oil by ExxonMobil is a non-zinc and non-chlorine lubricant formulated with high-quality basestocks which provide low oil consumption characteristics, high-temperature oxidation resistance, and thermal stability. These basestocks are combined with an Electro Motive Diesel (EMD) and General Electric (GE) endorsed additive package, resulting in an engine oil with well-balanced properties.
The optimized additive formulation in Mobilgard 409 NC has reduced ash content and advanced dispersant technology. Its alkalinity reserve provides excellent corrosion protection when using fuels containing up to 0.05 wt.% sulfur, including low and ultra low sulfur diesel fuels, even though metals such as steel, copper, silver and bronze are present. It has outstanding lubricating properties and is optimized for low and ultra low sulfur fuel use and takes into account after-treatment technologies. Mobilgard 409 NC exhibits good wear control for piston rings and cylinder liners.

Applications
Mobilgard 409 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 0.05 wt.%.
Mobilgard 409 NC has been approved by EMD and General Electric and is recommended for diesel engines manufactured by Alco, Detroit Diesel and Fairbanks Morse. The newest improvements in General Electric and EMD engines are modified piston rings and cylinder liners that have significantly reduced oil consumption. This drastic reduction in the amount of fresh oil makeup, plus the higher operating temperatures of the newer engines, places an extra burden on the oil. The good base number retention and improved oxidation inhibition of Mobilgard 409 NC provides excellent service under these conditions, even with extended oil drain intervals.
