Mobilgard M440 is an exceptional supreme-performance medium-speed trunk piston marine diesel engine oil designed to provide outstanding protection, cleanliness, and deposit control in engines operating on heavy fuel oil (HFO). It features a **40 BN** (Base Number) formulation and is engineered from high-quality base oils combined with advanced detergent-inhibitor technology to effectively neutralize high levels of strong acids from sulfur combustion, control piston crown and ring zone deposits, and minimize corrosive wear under severe marine operating conditions. Supplied in a **208-liter drum**, it is ideally suited for bulk maintenance, routine servicing, and high-capacity inventory requirements for main propulsion and auxiliary medium-speed diesel engines operating in commercial shipping, deep-sea transport, and power generation applications.
