Because HFO is the waste product of the crude oil refining process, it is relatively cheap, especially for larger vessels such as tankers, bulk carriers and container ships.[1] For example, while oil prices can change quickly, the price of a ton of HFO in October of 2016 was approximately $290.00 USD, while a ton of distillate fuel was $516.00 USD.[2]
