This episode is based on a discussion I had with an acquaintance at a barbecue. He, being the smarty pants that he is, asked "Do you know the difference between diesel and heating fuel?"... I didn't... I, being the smarty pants that I am, was annoyed by that. With a wry smile he suggested: "Better look it up then." And I did! The result is a not too shabby podcast episode on the difference between the two.
If you want to know why it is a bad idea to use heating fuel in your diesel engine, tune in!
