DMA, also known as Marine Gas Oil (MGO), is a high-quality marine distillate fuel designed for general-purpose use. It must be free from any traces of residual fuels, ensuring cleaner combustion and reduced emissions. DMA and DMX grades are typically used in Category 1 marine engines with a cylinder capacity of less than 5 liters. In contrast, DMB (Marine Diesel Oil, MDO) may contain traces of residual fuel, which can result in higher sulfur content and heavier emissions
