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 talks the value of fuel additives and other automobile additive products.

• Should I stay away from Stop Leak and Stop Slip types of products? Do they really help my car?
• Will additives ruin my car?
• Will fuel tank additives such as octane boosters cause my car to run more efficiently?
• 2005 Toyota Tundra: The clear coat on my truck keeps coming off. What can I do to fix this?
• 2005 Mercedes SL500: I’m being told that I need to have regular service checks done on my shocks due to the fact that this car has a fairly complicated system. Is that true?
• 2008 Honda Odyssey: Why is the power steering tight when the car is not moving but seems fine when the vehicle moves?
• I’m interested in getting an old Chevette and I’m wondering where the best place to find one is?
• Honda Hybrid: Where can I get my hybrid serviced besides a dealership?
• 2014 Jeep Grand Cherokee: I’m interested in getting some new 18” rims for my vehicle and I’m only finding them online. Are there any local shops that carry this size?
• 1992 Mazda Miata 49,000 miles: If I’m getting good oil reports back on the vehicle, is it necessary to change the oil as frequently as we’re told?
• 2005 Ford F150: Is there a valve adjustment I can do to help fix a tapping noise coming from the top side of the engine?
• I heard that you could seal up a hole in the radiator with an egg. Is this true?
• 2004 Acura: My manual vehicle is having problems with shifting into reverse and sometimes locks up. Do you know what could be causing this problem?
• 1993 Nissan Pickup: I have my truck regularly serviced but have been told that if transmission is doing fine that I don’t need to change out the fluid on a regular basis. Is this true?
• 2004 Ford Mustang: Should I use a cleaning additive if I’ve been servicing it regular and using premium oil?
