That's a very poor test, and the quantity is not what matters to the
chemicals partaking (or not) in the reaction :-) The local heat
capacity is. The concrete keeps the oil much cooler than is required
to *sustain* burning, and the hot fuser is not comparable to a slab of
cold concrete. Pour half a cup of petrol (er, gasoline) into a bucket
of water, drop in a match, and watch the match go out...
