Tire Rotation: Rotate tires every 5,000 to 7,500 miles to promote even wear and improve handling.

3. Fuel System Maintenance

Fuel Injector Cleaning: Use a quality fuel injector cleaner or have the injectors professionally cleaned to ensure optimal fuel delivery.
Fuel Quality: Use Top Tier gasoline to ensure cleaner fuel with fewer impurities.

4. Driving Behavior Modification

Adopt Smooth Driving Habits: Accelerate gently and maintain a steady speed to avoid unnecessary fuel consumption.
Reduce Idling: Turn off the engine if idling for more than a minute to save fuel.

5. Weight Management

Remove Unnecessary Items: Clear out any heavy items from the trunk or backseat that aren’t needed for daily use to decrease vehicle weight.
