How Do I Know When to Replace My Toyota RAV4's Air Filter?

I've heard that air filters play an important role in maintaining my Toyota RAV4's performance, but I'm not sure when to replace them. Can you provide some guidance?

Good question! Air filters should typically be replaced every 15,000-30,000 miles, depending on road conditions and driving habits. If you notice a decrease in fuel efficiency or a musty smell in your car, it may be time to change the filter.

I recommend checking your owner's manual for specific maintenance guidelines. It's also a good idea to visually inspect the air filter every few months to see if it looks dirty. If it appears clogged or discolored, it's time for a replacement.

In general, it's better to err on the side of caution and replace the air filter more frequently rather than less frequently. A dirty air filter can lead to reduced engine performance and increased emissions, so it's an important part of car maintenance.
