Biodiesel fuel almost eliminates the air pollution caused by petroleum based fuels. Toxins that can cause cancer are virtually cut to zero by the use of biodiesel fuel instead of regular diesel fuel. There is far less sulphur in biodiesel fuel, so the smell is also greatly reduced. Some have even reported a pleasant smell from the combustion of biodiesel, such as doughnuts or french fries. There is also less soot from biodiesel combustion than with petroleum fuels.
