Allinol is the fuel brand central to Miles Axlerod's international conspiracy in Pixar's Cars 2.
Axlerod promotes Allinol as an alternative fuel and uses the World Grand Prix to demonstrate that it can power high-profile racing vehicles. The public promotion makes the product appear environmentally friendly and commercially promising.
The espionage plot reveals that Allinol has a dangerous effect when exposed to a device that causes cars using it to malfunction. The scheme is designed to discredit alternative fuel and increase dependence on petroleum, while Axlerod's own identity is concealed behind the campaign.
Lightning McQueen initially uses Allinol during the races, while Mater's investigation helps uncover the danger. Rust-eze is McQueen's sponsor and Dinoco is another racing brand, but neither is the fuel at the center of Cars 2's conspiracy.
