In Pixar's Cars 2, Allinol is promoted as an environmentally friendly alternative fuel.
Allinol is introduced as the fuel used in the World Grand Prix, whose organizer Miles Axlerod presents it as a cleaner alternative to conventional fuel. The product becomes central to the film's conspiracy because electromagnetic weapons are used to make racers running Allinol appear to explode or malfunction during broadcasts. The scheme is intended to discredit the fuel and increase demand for another energy source.
Allinol is fictional and should not be confused with Rust-eze or Dinoco. Rust-eze is McQueen's sponsor, while Dinoco is a major racing brand. The fuel plot gives Cars 2 its environmental and geopolitical theme, while the World Grand Prix provides the public setting for the villains' plan.
