Have you ever heard about "Diesel de luxe"?
It has a sligthly higher BTU than Diesel No.2. It's called Kerosin in Germany and it's used for military airplanes. Do not use kerosene ! It's not the same!
Kerosin gives you that black smoke without the need of bigger injectors- simply add more air and you will get more power. German military trucks get Kerosin , when Diesel No.2 is in short supply in the field.
Of course there is one bad thing : Kerosin contains lead as a grease aid.
Maybe my comment is a little bit off topic, but I thought it's a nice to know thing.
