I would venture a guess that a fuel like bunker fuel, or maybe some other less-refined petroleum fuel would be a higher BTU fuel than diesel... likely won't have cetane rating worth a crap though.. and will pump out the particulates... and will require a centrifuge to process, as well as enlarged 2 micron fuel filters to protect your engine... oh wait, have all of the above.. so where do you get bunker fuel?
