Is it necessary to replace the air filter every time you change the oil? Not always, but it’s a good idea to check it. While oil changes are typically required every 3,000 to 5,000 miles, air filters usually last longer. However, replacing a dirty air filter can improve your car’s performance and fuel efficiency.
How Often Should You Replace Your Car’s Air Filter?
Replacing your car’s air filter is an important part of regular vehicle maintenance. Typically, air filters need to be replaced every 12,000 to 15,000 miles. However, this can vary depending on your driving conditions and vehicle type. If you frequently drive in dusty or polluted environments, you may need to replace the air filter more often.
Signs That Your Air Filter Needs Replacement
