How do I increase the fuel efficiency on my BMW X2?

I've noticed that my BMW X2 gets lower gas mileage than what's advertised. What are some ways I can improve the fuel efficiency on my car?

First, make sure your tires are properly inflated. Under-inflated tires can decrease gas mileage by up to 0.3% for every 1 psi drop in pressure. Also, avoid carrying unnecessary weight in your car, as this can also decrease fuel efficiency. Use cruise control when driving on the highway, and avoid excessive idling. Lastly, regular maintenance and tune-ups can help improve your car's fuel efficiency.

Consider using premium fuel instead of regular unleaded. While it may be more expensive, it can improve your car's performance and fuel efficiency. Also, try to drive at a consistent speed and avoid sudden acceleration and braking, as this can use up more fuel. Lastly, make sure your air filter is clean and replace it if needed to improve airflow.

Using a fuel additive can also help improve your car's fuel efficiency. Look for one that is specifically designed for your car's make and model. Additionally, avoid driving during rush hour traffic when possible, as stop-and-go driving can use up more gas. And don't forget to regularly check and replace your spark plugs for optimal performance.
