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.

Car Advice Done Right.
