Allinol is the World Grand Prix's official fuel in Pixar's Cars 2.
The fictional fuel is promoted by Sir Miles Axlerod, the organizer of the World Grand Prix. Its marketing presents Allinol as a clean alternative to gasoline, and the racers are encouraged to use it during the international competition. The fuel becomes central to both the public racing story and the hidden espionage plot.
Cars 2 reveals that Allinol is not as harmless as its promotion suggests. The fuel is connected to a scheme involving electromagnetic radiation and remote attacks on cars using it. Lightning McQueen initially chooses not to use Allinol, but the film's mystery ultimately exposes the danger behind the product. Allinol is fictional and should not be confused with real automotive fuels or with Dinoco, the long-running racing sponsor in the Cars universe.
