How can I optimize the fuel efficiency in my BMW 1 Series?

I recently bought a BMW 1 Series and I noticed that the fuel efficiency isn't as good as I expected. How can I improve it without sacrificing performance? Any advice?

First, make sure to properly maintain your car by regularly changing the oil and air filters. This can greatly affect fuel efficiency. Additionally, avoid aggressive driving habits like sudden accelerations and braking. Lastly, consider using higher quality fuel and make sure your tires are properly inflated for better fuel economy.

I have a BMW 1 Series myself and one thing that helped me improve fuel efficiency was using the car's eco mode. It adjusts the throttle response and reduces energy consumption. Also, try to avoid using AC unless necessary.

I would recommend checking for any small leaks that may be causing your fuel to slowly leak out. This can significantly affect fuel efficiency. Also, consider using a fuel additive to keep the engine clean and improve fuel economy.
