Their debut in television commercials on May 1, 1995, featured talking cars done in clay animation, with a variety of car colors each with different personalities. The commercials themselves, done in a similar fashion to the animated film and television series Creature Comforts, were crafted by Aardman Animations and used to promote Chevron with Techron. A year later, Chevron gas stations began selling the toy cars featured in the commercials. Chevron underestimated demand in 1997 and increased production to 700,000 on each of 4 or 5 new models at the time, compared to 500,000 in the previous year.
