Special guests include Joel Bartko of Arizona Import Specialists. Also on this show:

• What is a “mechanic in a bottle?”
• Why you should avoid anything that claims to stop leaks.
• The different types of additives available and which are most common.
• 2002 Mercedes Compressor: I recently purchased this vehicle. At around 150k miles, what type of maintenance should I be considering?
• 2005 Nissan Titan: I’ve noticed my paint as well as the paint fading on similar Nissan vehicles from this time period. Do you have any information about this?
• 2013 Dodge Journey: After having my transmission completely replaced, my car is still shifting hard into 3rd gear. What should I look into from here?
• 2003 Toyota Tundra: I’ve been told I have a cracked transmission. What is a reasonable price to pay for the repairs I need?
• 2006 Dodge SRT Charger: What parts should I look into replacing now that my car is ten years old?
• 2008 Ford Taurus: I’ve noticed a sputtering in my engine during turns. Is this a transmission issue?
• 2006 Toyota Corolla: I had a friend recommend that I use a Techron addictive. Would you recommend the same?
• 2009 Nissan Versa: I’ve had a lot of issues with this vehicle since I purchased it 2 years ago. I’m upside-down in my loan; would you recommend putting more money into this car or cut my losses?
