Allinol is the alternative fuel promoted in Pixar's Cars 2.
In Cars 2, Miles Axlerod introduces the World Grand Prix partly to demonstrate Allinol, presenting it as an environmentally friendly fuel that can power race cars. The product becomes central to the film's spy plot because its apparent benefits and its effects on racers are not what they initially seem.
The international race is used as a public test of Allinol. Lightning McQueen initially uses the fuel, while other competitors also become connected to the product. Mater, Finn McMissile, and Holley Shiftwell investigate a conspiracy involving the fuel and a group of villains seeking revenge against the racing world.
Allinol is a fictional product created for the film and should not be confused with Dinoco or Rust-eze. Dinoco is a racing and fuel brand from the Cars universe, while Rust-eze is Lightning McQueen's principal sponsor. The name Allinol is a visual and thematic part of Cars 2's technology-and-espionage storyline.
