Thank you Rudy. That was the answer that I was looking for. My original question was more on the order of a sanity check before I answered another group here. To answer some of the questions, I am not flicking lit cigarettes into buckets of liquids to see which ones blow up, I am not experimenting with the flammability of Mt. Dew, I have not OD'd on Mt. Dew. Of course, this could change is certain smart alec metallurgists nearby keep making snide remarks............. Never piss off a chemist..............

The chlorinated solvents have no flash point, and will not burn at all, that is one of the factors that made them popular. The general rule is that the flash point is that temperature that if the liquid is heated to, and a cigarette thrown into it, it will burst into flame. Clearly, that is a pretty low temperature for gasoline, and pretty high for motor oil. The chlorinated solvents will burn, but not at atmospheric pressure.
