Is diesel flammable or inflammable?
That’s because diesel is much less flammable than gasoline. In a car, it takes intense pressure or sustained flame to ignite diesel. On the other hand, if you toss a match into a pool of gasoline, it won’t even touch the surface — it ignites the vapors above the surface.

Is diesel or kerosene more flammable?
Diesel holds a flash point of 126 °F and an auto-ignition temperature of 493 °F. In my point of view, Diesel is more combustible than kerosene since 126 °F > 100 °F, but lower flash point temperature means the more flammable, so kerosene is slightly more flammable than diesel.
