Bumper to Bumper Radio, the car guys on KTAR, 92.3 FM in Phoenix, AZ, broadcast every Saturday from 11 AM to Noon. On this show, special guest hosts Spencer Doucet of H&I Automotive and Josh Dana of Dana Bros Automotive and Diesel Service talk about diesel oil, EGR problems, and keeping a CVT alive in the Arizona heat.

Also on this show:

  • Car Care Month and why tire pressure matters for handling, blowouts, and fuel mileage.
  • Engine air filters and cabin filters, and why a cheap filter is not always a bargain!
  • 2026 GMC Duramax: GM calls for 0W-20 oil. If longevity is the goal, should I step up to a 5W-40?
  • 2017 Toyota Corolla: My vehicle started ticking a few days after an oil change. Was something damaged? What could be causing this?
  • 2007 GMC 2500 HD: At 109k miles, I had an EGR code and then a mass airflow code. I cleaned the Y-bridge and it seems to run better. Do I still need to address any issues with the EGR?
  • 2009 Nissan Sentra: How often should I change my car's CVT fluid and filters?
  • 2003 Ford F-150: At 130k miles, I drained and refilled the transmission, and the dipstick is hard to read. How do I know when it is full?
  • 2018 Chevrolet 1500: I have an anti-lock brake warning. Am I okay to drive it, and is that related to the tire pressure light?
  • 2005 Chevrolet Duramax: If I only drive about 3,000 miles a year, do I still have to get emissions testing so regularly?

Cars talked about on this show are the 2026 GMC Duramax, 2017 Toyota Corolla, 2007 GMC 2500 HD, 2009 Nissan Sentra, 2003 Ford F-150, 2018 Chevrolet 1500, and the 2005 Chevrolet Duramax.
