Refined petroleum products used as a fuel for home heating and industrial and utility boilers.' FUEL OIL' is divided into two broad categories, distillate fuel oil, also known as No. 2 fuel, gasoil, or diesel fuel; and residual fuel oil, also known as No. 6 fuel, or, outside the United States, just as fuel oil. No. 2 fuel is a light oil used for home heating, in compression ignition engines, and in light industrial applications. No. 6 oil is a heavy fuel used in large commercial, industrial, and electric utility boilers.
