Allinol is the fuel brand used in the World Grand Prix plot of Pixar's Cars 2.
Allinol is promoted as an environmentally friendly alternative fuel by Sir Miles Axlerod, the organizer of the World Grand Prix. The film's conspiracy depends on the fuel: electromagnetic pulses are used to make cars running on Allinol explode or malfunction, turning the resulting disasters into propaganda against alternative energy.
Lightning McQueen initially agrees to use Allinol in the race. Mater becomes suspicious after noticing unusual behavior connected with the fuel and is pulled into the investigation. The plot combines racing with spy-film elements, including secret agents, surveillance, and an international criminal network.
Rust-eze is Lightning McQueen's main sponsor, while Dinoco is a prominent fictional petroleum company and racing sponsor in the series. Octane Gain is another fictional racing brand. None of those names is the fuel at the center of Cars 2's conspiracy; that product is Allinol.
