Mobilgard M440 40 BN Engine Oil

The Mobil Mobilgard M440 is a high-performance engine oil specifically formulated for demanding marine applications, particularly for vessels operating on heavy fuel oil (HFO). With a viscosity grade of ISO 40, this oil is engineered to provide exceptional protection and performance in deep-sea, coastal, and river ships. Key features of Mobilgard M440 include excellent high-temperature oxidation resistance, ensuring stability under strenuous operating conditions. It boasts outstanding compatibility with residual fuels and good thermal stability, minimizing the risk of sludge formation and breakdown. The oil's low volatility contributes to reduced consumption, while its high load-carrying properties protect critical engine components under heavy stress. A significant benefit of Mobilgard M440 is its robust corrosion protection. The oil's high alkalinity reserves effectively neutralize the strong acids generated from high-sulfur fuels, thereby reducing engine corrosion. This protection helps to lower maintenance and repair costs and extends the operational life of the engine. Furthermore, the oil offers unsurpassed engine cleanliness and protection, with excellent Base Number (BN) retention and resistance to viscosity increase, which helps to maximize component life and extend cleaning intervals. Mobilgard M440 contributes to engine longevity through its advanced detergency and dispersancy properties, keeping critical areas like camshafts and crankcases clean. It also optimizes the life of wear surfaces with its superior anti-wear characteristics and minimizes oil consumption due to its low volatility base stocks.
