In Pixar’s Cars 2, Allinol is the fuel promoted for the World Grand Prix before the sabotage plot is revealed. The fictional alternative fuel is presented as a cleaner choice for the international racing series.
Miles Axlerod launches the World Grand Prix to demonstrate Allinol’s performance and encourage its adoption. The races are held in Japan, Italy, and England, and the fuel becomes a central part of the film’s mystery. A hidden device causes cars using Allinol to behave dangerously, making the product appear unreliable.
The plot eventually reveals that the fuel controversy is being manipulated. The Lemons, a group of criminally minded cars, use the sabotage to discredit Allinol and benefit from the resulting public reaction. Mater becomes important to uncovering the scheme after he is mistaken for an American spy. Allinol is fictional; it should not be confused with Dinoco, the racing sponsor from the series, or Rust-eze, Lightning McQueen’s sponsor.
