Barry Diesel is a minor character in Cars.


"Barry loves Dinoco oil. He starts his day off with Dinoco Extreme Octane to give him that extra kick in the bumper, and then it's gallon after gallon of Dinoco Regular to keep him running smoothly all day. However, his wife thinks it's about time Barry switched to Dinoco Light."[1]

In the film, he is seen attending the Piston Cup races at the Motor Speedway of the South and Los Angeles International Speedway, sipping on Dinoco Light oil.


  • According to Car Finder, Barry is a 1975 Silver Liner Coach V-8. His design is also similar to a 1983 Winnebago Brave.
  • Barry's "love" for Dinoco oil is clearly a reference to alcohol addictions. Dinoco oil is the Cars world equivalent of beer, and Dinoco Light is probably a parody of the popular beer brand Bud Light.
  • At the Motor Speedway of the South, his eyes are brown. However, they are green during his appearance at the Los Angeles International Speedway. It could, however, be that he was wearing contact lenses in one of those scenes.
