Dinoco is the sponsor whose logo appears on The King in Pixar's Cars (2006).
The King is a veteran blue race car modeled after a Plymouth Superbird, and Richard Petty provides his voice. Dinoco is presented as one of the most prestigious sponsors in the Piston Cup, making the company’s branding important to the film’s racing world.
Rust-eze is Lightning McQueen’s original sponsor, while Chick Hicks is associated with Hostile Takeover Bank. The Piston Cup is the championship trophy and racing series, not a sponsor.
The Dinoco brand also connects Cars with Pixar’s earlier Toy Story films, where Dinoco appears as a fictional gas station. In Cars, Dinoco’s blue styling and helicopter help distinguish its racing identity.
