fun fact before they realised you could run a diesel engine on a petroleum byproduct (which was named diesel after the engine) all diesel fuel was biodiesel.

when they figured out you could use a petroleum byproduct to run a diesel engine they decided to put the seed oils into food instead of using them as fuel(because telling the subsidized canola farmers to stop growing canola wasn't an option, it would have destroyed the global economy)

so now we are all eating diesel fuel and engine lubricants in our food while burning toxic substances for fuel.
