Ron Ananian The Car Doctor

Ron Ananian, The Car Doctor takes on one of the most debated topics in automotive maintenance this week: oil change intervals. After an Instagram post sparked a flood of listener questions, Ron breaks down why modern engines are harder on oil than ever before—and why the “one-size-fits-all” oil change recommendation no longer works. From turbochargers and direct injection to short-trip driving and long-term vehicle ownership, Ron explains how driving habits, maintenance philosophy, and engine design all affect oil life and long-term reliability.
Then, Ron welcomes Aaron Schaffer of Standard Motor Products for an inside look at modern fuel injectors. Learn how injectors are manufactured, why spray pattern precision matters, what causes injectors to fail, and why replacing just one injector may not always solve the problem. It’s a fascinating conversation about the technology quietly powering every modern engine on the road today.

This is a Classic Car Dr episode from the past. Ron Ananian, The Car Doctor, opens the hour discussing a question he was hearing more and more often — why are so many vehicles being recalled? Ron explains how growing vehicle complexity, electronics, software integration, and manufacturing challenges all play a role in today’s expanding recall landscape.
Along the way, Ron helps diagnose a 1999 Mercury Grand Marquis with a flashing red warning light and intermittent shutdown problem, takes on the mystery of a “possessed” 2003 Cadillac CTS with strange electrical behavior, and discusses the well-known oil consumption concerns affecting the 2006 Toyota RAV4.
Also this hour, Ron talks with Rich Dwyer of K&N Engineering about performance and maintenance, shares his thoughts on what truly makes a good repair shop, and helps track down electrical problems on a 2002 Dodge Dakota.

Ron Ananian, The Car Doctor, opens the hour continuing the conversation about fuel economy and why modern vehicles can lose efficiency long before a check engine light ever comes on. With Memorial Day and summer travel season approaching, Ron explains how issues with fuel trims, EVAP monitors, thermostats, wheel speed sensors, batteries, and basic maintenance can quietly affect fuel mileage and vehicle reliability. He also reminds listeners why now is the time to inspect tire pressure, batteries, fluid levels, and wiper blades before getting stranded roadside during holiday travel.
Later in the hour, Ron helps a Toyota Tacoma owner work through an intermittent misfire problem by explaining how modern computers actually detect misfires and why live scan tool data is critical for proper diagnosis. Another caller describes a rough-running Chevy Sonic with a long-ignored check engine light, leading to a conversation about how vehicles adapt around existing faults and why delayed repairs can create additional hidden problems. Ron also helps a repair shop owner diagnose a difficult Chevy Traverse no-start condition involving CAN bus communication faults, module diagnostics, and theft deterrent issues in modern vehicles.
Ron wraps up the hour with a warning about a General Motors brake fluid recall involving certain AC Delco DOT 3 brake fluid products and reminds listeners to check affected part numbers before summer driving season gets underway.
