In Pixar's Cars 2, Allinol is the fuel marketed as an alternative to gasoline during the World Grand Prix.
Allinol is presented as an environmentally friendly fuel developed by Miles Axlerod, the billionaire who organizes the international race. Its promotion encourages cars from different countries to use it during the competition.
The plot later reveals that the fuel has been manipulated to cause dangerous engine reactions. The conspiracy is designed to discredit alternative fuels and make gasoline appear indispensable, giving the villains a financial motive.
Allinol is fictional and belongs specifically to Cars 2's espionage story. It should not be confused with Rust-eze, the bumper ointment brand sponsoring Lightning McQueen, or Dinoco, the major racing and fuel brand associated with The King and other characters.
