What is Virgin Fuel Oil D6?

Virgin Fuel Oil D6 is a high-viscosity residual fuel oil — the "Bunker C" class — used by power plants and very large boiler installations. It must be stored heated and is moved in heated-coil tankers; its low price per unit of energy is what attracts utility-scale buyers. D6 is quoted per US gallon. Related heavy grades: Mazut M100 and Fuel Oil CST-180.
