In Pixar's Cars, The King's blue racing team is sponsored by Dinoco.
Dinoco is one of the most recognizable fictional brands in the Cars universe. Its blue, orange, and white color scheme is associated with The King in the first film, and the company's sponsorship represents the prestige Lightning McQueen hopes to gain by winning the Piston Cup.
Rust-eze sponsors Lightning at the start of the story, while Chick Hicks races for Hostile Takeover Bank. These sponsors are not interchangeable: each has a distinct logo, color scheme, and role in the Piston Cup field. Dinoco's sponsorship becomes part of the prize and the film's final decision.
The name also connects Cars to Pixar's wider visual world. Dinoco first appeared as a fictional gas-station brand in Toy Story, years before becoming a major sponsor in Cars. The recurring logo is an example of an easter egg shared across Pixar films.
