Dinoco is the fictional fuel brand that sponsors the Piston Cup in Pixar’s Cars.
The Dinoco logo is a blue dinosaur, and the brand’s signature color scheme makes it one of the most recognizable fictional companies in the Cars universe. The Dinoco sponsorship is especially important because the Dinoco 400 is the race where Lightning McQueen, Chick Hicks, and Strip Weathers compete for the championship in the first film.
Rust-eze is Lightning McQueen’s sponsor, identified by its medicated bumper ointment branding. Octane Gain is another racing sponsor seen in the series, but neither is the major fuel brand associated with the Piston Cup’s sponsorship.
Dinoco also appears in other Pixar films, including Toy Story, where it is associated with a gas station and a toy crane machine. This recurring brand is an example of Pixar’s shared visual easter eggs, although the Cars story gives Dinoco its most developed fictional business identity.
