Mobilgard M420 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 **20 BN** (Base Number) formulation and is engineered from high-quality base oils combined with advanced detergent-inhibitor technology to effectively neutralize acids from sulfur combustion, control piston crown and ring zone deposits, and minimize corrosive wear under severe marine operating conditions. Supplied in a **1000-liter intermediate bulk container (IBC)**, it is ideally suited for high-volume bulk storage, port operations, and large-scale maritime facilities servicing main propulsion and auxiliary medium-speed diesel engines in commercial shipping, deep-sea transport, and power generation applications.
