In Pixar’s Cars 2, the World Grand Prix racers use the fictional fuel Allinol.
Allinol is presented as an alternative fuel promoted by Sir Miles Axlerod, the organizer of the World Grand Prix. Lightning McQueen chooses to use it in the races, despite criticism from the oil-powered racer Francesco Bernoulli.
The conspiracy at the center of Cars 2 involves an electromagnetic pulse weapon. The weapon makes cars using Allinol lose control or appear to suffer dangerous failures, creating public fear about the fuel and damaging Axlerod’s larger plan to discredit alternative energy.
Mater, Finn McMissile, and Holley Shiftwell uncover the scheme. Allinol is not a real commercial fuel; it is a fictional plot device created for the film’s espionage story. Rust-eze and Dinoco are separate fictional brands associated with Lightning’s racing career.
