Heptane is less likely to flame, in fact one key fact about
heptane is you can put a match out in it.

With heptane's flash point of 25 deg F, I don't think so, depending on
your
definition of "put out".

Let's see...

Gasoline flash point -50 C
Heptane flash point -4 C
Ronsonol lighter fluid flash point +6 C
Kerosene flash point +38 C
Mineral spirits flash point +20 to +50 C

Flash point is the "lowest temperature at which [the chemical] can form an
ignitable mixture with air."

These are from a variety of online MSDS. BTW, gasoline is a mixture and is
much more flammable than pure octane.
