In Pixar’s Cars 2, the World Grand Prix cars initially use the alternative fuel called Allinol.
Allinol is promoted as an environmentally friendly fuel for the international race. Its public launch is tied to the World Grand Prix, where competitors are expected to use it instead of conventional fuel. The choice becomes a central part of the film’s mystery.
A conspiracy uses an electromagnetic pulse weapon to make cars running on Allinol appear to suffer dangerous failures. The plot is intended to discredit the fuel and create fear about alternative energy. Mater becomes involved after discovering that the apparent accidents are not ordinary engine problems.
Allinol is fictional and belongs to the Cars 2 storyline. It should not be confused with Rust-eze, the sponsor associated with Lightning McQueen, or Dinoco, a fictional petroleum company and racing sponsor seen across the Cars series.
