I sent this reply a few days ago:

Diesel fuel needs to burn easily so it ignites the instant it is injected to
produce a nice flame from the injector.  Gasoline is made to resist ignition
so it doesn't ignite until after the spark fires.  Gasoline in a diesel will
form a cloud of fuel in the chamber then detonate in a really big bang.

Its funny how fuel made to resist detonation in a spark ignition engine
detonates badly in a compression ignition engine and vice versa.
