Maintaining your Toyota RAV4's catalytic converter is crucial for peak performance and emissions control. Regular inspections can catch early signs of wear, such as reduced fuel efficiency or a sulfur-like smell, indicating it may be time for a replacement. To extend its lifespan, ensure timely oil changes, use the correct fuel type, and avoid short trips that prevent the converter from reaching optimal operating temperature.
