How can I maximize the fuel efficiency on my BMW 4 Series?

I've noticed that my fuel consumption has been higher than expected on my BMW 4 Series. Is there any way to improve its fuel efficiency?

First, make sure to keep your tires properly inflated. Under-inflated tires can cause your car to use more fuel. Also, try to avoid unnecessary idling and driving at high speeds. It's also a good idea to have your car serviced regularly, as a well-maintained engine is more fuel efficient.

Another tip is to avoid carrying excess weight in your car. The heavier your car is, the more fuel it will use. Also, using cruise control on the highway can help maintain a consistent speed and save fuel. And don't forget to use the proper grade of gasoline recommended for your BMW.
