Fillmore sells organic fuel at his Radiator Springs shop in Pixar's Cars (2006).
Fillmore is the town’s Volkswagen Type 2-style hippie van and operates Fillmore’s Taste-In, a business associated with alternative fuel. His character represents counterculture ideas and environmental concerns within the film’s otherwise automobile-centered world.
The organic fuel detail is part of the joke surrounding Fillmore: he promotes a more natural alternative while his neighbor Sarge, a military-style Jeep, strongly prefers conventional attitudes and products. Their opposing personalities create one of the town’s recurring comic pairings.
Allinol belongs to the plot of Cars 2, where it is marketed as a modern alternative fuel during the World Grand Prix. It is not the fuel Fillmore sells in the first Cars film.
