Bumper to Bumper Radio, the car guys on KTAR, 92.3 FM in Phoenix, AZ, broadcast every Saturday from 11:00 am to noon. On this show, Dave Riccio of Tri-City Transmission in Tempe, AZ and Matt Allen of Virginia Auto Service in Phoenix, AZ talk about what happens to your vehicle internally after pumping the incorrect type of fuel. Also on this show:


  • Information about the incident in Buckeye where a fuel tank deliverer filled the unleaded tank with diesel.
  • How pumping the wrong fuel into your car can be harmful.
  • What components of your vehicle are affected by driving with the wrong type of fuel?
  • Jeep Grand Cherokee: Is there a shop you recommend to have my engine rebuilt?
  • Nissan Frontier: After a diagnosis, I’ve been told that there’s an issue with my fuel sensor. My gas gauge has also been working strangely. Is this an issue I can solve by myself?
  • Toyota Sienna: The outside edges of my front tires are wearing faster than normal. Is this an alignment issue?
  • 2009 Dodge Ram 1500: I was one of the customers who filled my truck with diesel in Buckeye. Here’s what happened to my truck.
  • 2014 Toyota Sienna: My AC has a smell to it when you turn it on. After changing the filter, the problem persists. What could be causing this?
  • 2005 BMW Z4: I’ve noticed a strange blue smoke when I start my car. Could I be burning some type of fluid?
  • 2005 Ford Explorer: I’ve noticed some sputtering while stopped, but never in park or neutral. Any idea what the reason for this is?


Cars talked about on this show are the Jeep Grand Cherokee, Nissan Frontier, Toyota Sienna, 2009 Dodge Ram 1500, 2014 Toyota Sienna, 2005 BMW Z4, and the 2005 Ford Explorer
