A gallon of roughly jet fuel (gasoline) (1) can drive roughly a ton of metal (your car) roughly 30 miles (2).

2 WTCs weighed roughly 1M tons (3). So, the equivalent energy of one gallon would move them at most a millionth of a car's MPG, or 30 / 1M = 3*10-5 miles, or about 2 inches.

But of course, a "jet crashing into a building" is not a very efficient automobile. So, lots of that energy ends up as heat instead of just motion - which is why you need 10k gallons instead of just one. Heat which might, say, melt steel beams.

TL;DR: Inconclusive. I won't waste any more time on this.
