How can I optimize the fuel efficiency of my BMW car?

I have a BMW car and I want to improve its fuel efficiency. What are some tips and suggestions I can follow to achieve this?

Firstly, make sure your tires are properly inflated at all times. This can greatly improve your car's fuel efficiency. You can check the recommended tire pressure for your car model in the owner's manual. Additionally, avoid speeding and aggressive driving as it can also lead to increased fuel consumption.

Regularly maintain your car's engine by following the recommended service schedule. This will ensure that your car is running at its optimum level and will improve its fuel efficiency. Also, try to plan your trips and avoid unnecessary idling to save fuel.

Consider using cruise control while driving on the highway. This can help maintain a consistent speed and can improve your car's fuel economy. Moreover, remove any unnecessary weight from your car as it can also contribute to increased fuel consumption.
