How can I improve fuel efficiency in my BMW i7?

I have noticed that my BMW i7 is not getting as good gas mileage as it used to. What steps can I take to improve its fuel efficiency?

First, make sure your tires are properly inflated. Under-inflated tires can decrease fuel efficiency. Also, try to avoid rapid acceleration and braking, as this can use up more fuel. Lastly, consider getting your car's fuel system cleaned, as build-up can also decrease fuel efficiency.

Have you considered using a fuel additive? Some additives claim to improve fuel efficiency by cleaning the engine and optimizing combustion. Just make sure to do your research and choose a reputable brand.

In addition to maintaining your car's engine and tires, your driving habits can also greatly affect fuel efficiency. Try to anticipate traffic and use cruise control when appropriate. And remember, the speed limit is not a suggestion - driving at a consistent speed can improve gas mileage.
