The Piston Cup: A Big Circus of Fake Brands
In real life, a NASCAR car is a rolling billboard, covered in logos from the grille to the bumper. Pixar understood this well: to give the Piston Cup its authentic flavor, the studios invented dozens of fake brands that are both credible and hilarious.
Each sponsor imitates the famous contingency sponsors, those small stickers that real racing teams put on their cars. Except here, everything is re-imagined for the automotive world: they no longer sell human drinks or medicines, but products for car bodies, with irresistible double-meaning slogans.
The result: a catalog of non-existent brands that playfully parody real companies. Here is the complete guide to this little advertising world, from the two rival giants to the most discreet gags seen on the bodywork.

Rust-eze vs. Dinoco: The Great Rivalry (and HTB)
Rust-eze is the most endearing sponsor of the saga: a medicated bumper ointment manufactured by two rusty brothers, Rusty and Dusty. Their product treats old, damaged bumpers, and it's thanks to them that Lightning McQueen sports his famous number 95. All the humor comes from the slightly awkward medical theme, with its unapologetic "rear-end formula."
Opposite them stands Dinoco, the prestigious blue oil major, the dream sponsor of all drivers. According to the Pixar Cars Wiki, Dinoco supports The King (Strip Weathers) in the first film, then his nephew Cal Weathers in Cars 3. It's the Holy Grail of sponsorship: personal helicopter, showgirls, and the Texan magnate, Tex Dinoco, at the head of the empire.
The third character completes the picture: HTB, for Hostile Takeover Bank. This acidic green banking sponsor perfectly matches its protégé, the cunning Chick Hicks, who is ready to do anything to snatch the Piston Cup. It's hard to imagine a more cynical brand for a proven cheat.

The Bestiary of Comical Sponsors
Beyond the top three, the track is teeming with secondary brands, each funnier than the last. In terms of drinks, Nitroade is a supercharged energy drink, while N2O Cola runs on nitrous oxide, and Transberry Juice offers a fruit juice ("trans" + berry) for thirsty cars.
The pharmacy section is a festival of puns. Gasprin relieves "hood-aches"; Tank Coat "soothes upset tanks" like an antacid; Sputter Stop promises "cold engine relief" like a syrup; and RPM is sold as a "nighttime backfire suppressor," a nod to evening medications.
For maintenance and mechanics, Octane Gain acts as a fuel additive, Vitoline targets "older but active cars," Mood Springs handles suspensions, Re-Volting sells reconditioned alternators, and No Stall promises to get you to the finish line without ever stalling.
Finally, the hygiene and comfort department is not lacking in wit. Leak Less boasts "adult anti-leak protection" worthy of a diaper commercial, Trunk Fresh deodorizes trunks, View Zeen treats foggy windshields, Spare Mint perfumes tires, and Clutch Aid applies "bandages" to tired clutches.

Nods to Real Brands
The wit of these sponsors lies in their parody of real companies. Nitroade mimics the famous Gatorade for athletes, Gasprin reworks aspirin, and Vitoline blends two well-known motor oils, Valvoline and Havoline. A nod within a nod: Valvoline actually sponsored the Cars movie.
The list of references continues: View Zeen evokes Visine eye drops, Spare Mint plays with "spearmint," Mood Springs refers to Moog suspension parts as much as to "mood swings," and Clutch Aid sounds like both Band-Aid and Kool-Aid.
Even the giants are homages. Dinoco and its dinosaur allude to Sinclair Oil and its prehistoric mascot, with a touch of Sunoco, the official fuel of NASCAR. As for Leak Less, its "rear-end protection" gag shamelessly parodies adult incontinence products. A true masterpiece of re-imagination.

Sponsors and Drivers: What Changes Between Cars 1 and Cars 3
A word of caution for purists: the sponsor-driver-number associations are not set in stone. Between Cars (2006) and Cars 3 (2017), Pixar shuffled the cards, and several teams changed colors as well as drivers.
According to the Pixar Cars Wiki, for example, Gasprin is associated with driver Floyd Mulvihill (No. 70), Octane Gain with Bobby Swift (No. 19), Vitoline with Brick Yardley, and Re-Volting with the Next-Gen generation of Cars 3. These attributions vary from one film to another, so it's best to cite them with caution.
What remains solid and verifiable, however, are the brands themselves and their gags. This is where Pixar's discreet genius lies: a complete, coherent, and parodic advertising universe, hidden on car bodies that we only glimpse for a fraction of a second.
