What is the name of the fuel introduced in Pixar’s Cars 2?

The fuel introduced in Pixar’s Cars 2 is Allinol.

Allinol is presented as an environmentally friendly alternative fuel developed for the World Grand Prix. Sir Miles Axlerod promotes it as a clean-energy breakthrough, and the race is intended to demonstrate that high-performance cars can use it around the world.

The film’s central conspiracy reveals that Allinol is not as simple as its public image suggests. Cars using the fuel are targeted by a device that causes their engines to malfunction or explode. The plot links the fuel, the race broadcasts, and a larger attempt to discredit alternative energy.

Allinol is a fictional product created for the film, not a real commercial fuel. It is sometimes confused with the oil-based products and real alternative fuels discussed outside the story. The name matters because the World Grand Prix’s entire public purpose and secret danger revolve around it.
