Use Fuel Additives: Add a fuel injector cleaner to the gas tank during refueling, following the product’s instructions for dosage.
Quality Fuel: Always fill up at reputable gas stations and use fuel with the recommended octane rating.

4. Driving Habits Improvement

Adopt Eco-Friendly Driving Techniques: Encourage smoother acceleration and deceleration, reducing high-speed driving and excessive idling.
Plan Routes: Use navigation apps to avoid traffic and select routes that minimize stop-and-go conditions.

5. Regular Maintenance
