Bunker Fuel Definition: (click here) there are two basic types of marine fuels - distillate and residual. A third type is a mixture of these two, commonly called "intermediate".  Distillate fuel is composed of petroleum fractions of crude oil that are separated in a refinery by a boiling or "distillation" process. Residual fuel or "residuum"  is the fraction that did not boil, sometimes referred to as "tar" or "petroleum pitch". Fuel for marine use in engines and boilers has the following types and grades:
