An oil burner company ad used to show a torch extinguished by shoving it into a pail of heating oil. (Don't try this at home).
Why does a cigarette butt go out and not cause a fire or explosion when dropped onto/into a pail of gasoline?
Not enough heat and too rich in fuel to combust. Think of it like an engine. Too much or too little fuel = no boom. Not enough heat from the spark plug = no boom. Combine the two and you get even more failure to go boom.
A cig has enough heat from the ember to ignite vapors, which will then propagate to the fuel as they generate more heat. Similar to sticking a torch into a drum of oil. Unless the oil is VERY hot, there just isn't enough heat to fuel mass to cause a fire.
