Not really. A change of phase means the same molecule going from solid to liquid to gas (or back from gas to liquid to solid). When you burn gasoline (or anything else), you are actually changing its chemical nature through oxidation (buring) so that it no longer exists as gasoline and the result is not the same type of molecule with which you started.

No! Burning gasoline undergoes an irreversable change. Phase changes are reversable through a change in temperature or pressure.
Before gasoline burns it evaporates and that is a phase change. If cooled the gasoline will condense.

No
Gasoline changes phase from liquid to gas due to the heat of the neaby flame before it can combust, this is a change of phase.
However it is already a gas, before it combines in a red-ox reaction wiht oxygen (also a gas) to produce CO2 (a gas too)
