Diesel minus the freezing thing? What I would prefer you to request is quite possibly a liquid that burns as slow as coal. Not this, for this has been a subject of rejection for quite some time, due to the fact that many people, like you, don't give very detailed requests. Please read the element suggestion rules and regulations before requesting trivial...requests. there are already ways to mix liquids and whatnot to create this type of effect.
Try alcohol in powdersim. If you like it, then suggest it here is win32 and here is lin32. just download that for whichever operating system you have and try it out. ALCO is in the explosives section and it does more than just burn up. If you want to know everything it does, just ask.
