Furnace Oil
Dark, viscous residual fuel derived from crude oil distillation, also known as Bunker Oil or Fuel Oil.
Introduction
Furnace Oil is a dark, viscous residual fuel derived from crude oil distillation. Also known as Bunker Oil or Fuel Oil, its key characteristic is viscosity, which determines heating and handling requirements. Common grades include 180 cSt and 380 cSt.
