Ensure your tires are properly inflated. Underinflated tires can decrease fuel efficiency.

Avoid aggressive driving habits such as rapid acceleration and braking, as they can negatively impact fuel efficiency.

Consider using fuel additives or switching to a higher quality fuel for better performance and efficiency.

Regularly maintain your vehicle by getting routine oil changes and tune-ups, as a well-maintained car can lead to better fuel efficiency.

Utilize cruise control when driving on highways to maintain a consistent speed, which can help improve fuel efficiency.
