In Pixar's Cars 2, what fuel is promoted by the World Grand Prix sponsor Allinol?

In Pixar's Cars 2, Allinol promotes alternative fuel during the World Grand Prix.

The fictional fuel is presented as a clean substitute for traditional petroleum-based fuel. Miles Axlerod, the former oil tycoon who becomes a central public figure in the story, promotes Allinol as part of the international racing event.

The film's conspiracy depends on the fuel's hidden danger. A device causes cars using Allinol to malfunction, creating dramatic incidents that appear to discredit alternative fuel. The plot eventually reveals that the public campaign is connected to a plan involving oil interests and control of the racing narrative.

Allinol is invented for the film, so it is not the name of a real commercial fuel. It is also distinct from the real-world terms ethanol, biodiesel, and electric power, which are not interchangeable labels for the fictional product.
