In Pixar's Cars 2, Sir Miles Axlerod promotes Allinol as an alternative fuel. He presents it as a clean, environmentally friendly product during the World Grand Prix, but the fuel is central to the film's secret conspiracy.
Allinol is designed to make cars explode when exposed to a remote electromagnetic pulse. Axlerod's plan is to discredit alternative fuel by causing spectacular failures during the races, encouraging the continued dominance of petroleum-based fuel.
The plot makes Allinol a fictional product rather than a real commercial fuel. The name is a pun on “all” and “oil,” while Axlerod's own identity is tied to the movie's mystery. The story also explains why the racers and spies become involved in a conflict that goes beyond the competition itself.
