In Pixar's Cars 2, the fictional alternative fuel is called Allinol.
Allinol is introduced as an environmentally friendly fuel used in the World Grand Prix. Its promotion brings together racers, manufacturers, and international audiences, but the product becomes central to the villains' conspiracy. Professor Z and the Lemons manipulate events to make Allinol appear dangerous and damage public confidence in alternative fuels.
The name resembles “all-in-oil,” fitting the film's wordplay about vehicles and energy. Cars 2 uses the fuel plot to give its racing story a global espionage framework, with Mater and Finn McMissile uncovering the scheme.
Allinol is not the same as Rust-eze or Dinoco. Rust-eze is Lightning McQueen's sponsor, and Dinoco is a fictional petroleum brand and racing sponsor. The fuel is also invented for the film rather than being a real commercial product.
