Allinol is the fictional clean fuel promoted in Pixar's Cars 2.
Sir Miles Axlerod introduces Allinol as an environmentally friendly alternative to traditional petroleum fuel. The product becomes the basis of the World Grand Prix, an international racing event designed to demonstrate its supposed benefits.
The fuel is central to the film's mystery. Axlerod secretly modifies cars running on Allinol so that an electromagnetic weapon can make their engines overheat or fail. He then intends to blame the fuel and turn public opinion against it.
Allinol should not be confused with Rust-eze, the fictional bumper-ointment brand that sponsors Lightning McQueen, or Dinoco, the famous racing and fuel company within the Cars universe. Cars 2 uses these invented brands to combine automotive satire, spy-film plotting, and the franchise's continuing focus on racing culture.
