What fuel is central to the racing plot in Pixar's Cars 2?

Allinol is the fuel central to the racing plot in Pixar's Cars 2.

Sir Miles Axlerod promotes Allinol as an alternative fuel for the competitors in the World Grand Prix. The film initially presents it as a cleaner substitute for conventional fuel, but the product becomes part of a scheme involving electromagnetic radiation and the racers who use it.

Lightning McQueen chooses to use Allinol during the competition, while some characters question its safety. The fuel's effects help connect the sports story to the spy-adventure plot involving Finn McMissile, Holley Shiftwell, and Mater.

Allinol is fictional and should not be confused with real automotive fuels or with Rust-eze, the bumper-ointment brand that sponsors McQueen. Dinoco is another fictional company in the franchise, but it is associated primarily with racing sponsorship and petroleum imagery rather than the Cars 2 fuel conspiracy.
