In Pixar's Cars 2, Allinol is promoted as the clean alternative fuel powering the World Grand Prix cars.
Allinol is presented by Miles Axlerod as a supposedly environmentally friendly fuel. The World Grand Prix is designed in part to advertise it, and racers are encouraged to use it during the international competition.
The fuel is actually connected to the film's central plot. A group of lemons plans to make Allinol appear dangerous by using electromagnetic devices to cause cars running on it to malfunction. Their scheme is intended to discredit alternative fuel and increase demand for petroleum.
Allinol is fictional and should not be confused with a real commercial fuel brand. The name is also distinct from Dinoco, the fictional company associated with The King and later Lightning McQueen. The fuel plot gives Cars 2 its espionage and environmental themes.
