Gasoline has a flash point of -45°F and an auto-ignition temperature

auto-ignition temperature

The autoignition temperature or kindling point of a substance is the lowest temperature in which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark. This temperature is required to supply the activation energy needed for combustion.

of 536°F. [1] Gasoline's aviation fuel counterpart Kerosene holds a flash point of 100°F and an auto-ignition temperature of 428°F.

At what temperature does gasoline catch fire?

"The most commonly known flammable liquid is gasoline. It has a flash point of about −50° F (−65° C). The ignition temperature is about 495° F (232(232° C) [sic], a comparatively low figure."

Can gasoline randomly ignite?

The tests show that under certain limited conditions—including a very low volume of gasoline left inside—a flashback explosion can occur inside a plastic gas can, when gas vapor escaping the can contacts a source of ignition such as a flame or a spark.
