How do I optimize fuel efficiency in my BMW 3 Series?

I recently purchased a BMW 3 Series and I'm wondering how I can improve its fuel efficiency. Any tips or recommendations?

First and foremost, regular maintenance is key. Make sure to have your car's oil changed regularly and keep up with other routine maintenance tasks suggested by the manufacturer. This will not only improve your fuel efficiency, but also prolong the life of your car.

Another way to improve fuel efficiency is to avoid unnecessary idling. If you are going to be stopped for more than one minute, it is better to turn off your engine. This will save you fuel and reduce emissions.

Properly inflate your tires and check them regularly. Under-inflated tires can decrease fuel efficiency, so make sure they are inflated to the recommended pressure.
