Ouch! To bad!

If your still not sure, then pour a little out into an open pie tin and toss
a match in to it. If it flashes right up, then it's most likely it has gas
in it.. The straight diesel will just burn like kerosene (may even put the
match out).

Steve, have you ever done this? I've seen this from a distance of 50 yards with
the fire set by Fire Department personnel, and it was impressive. I'll tell you
this: Anyone close enough to have "toss(ed) a match in to it" would have been
burned seriously.

Not trying to one-up, but that advice scares the Hell out of me.
