How can I improve gas mileage in my BWM car?

I have noticed that the gas mileage in my BWM car has been decreasing. What are some tips or techniques I can use to improve the gas efficiency in my car?

One way to improve gas mileage is to make sure your tires are properly inflated. This will reduce the amount of resistance your car has to overcome while driving.

Another tip is to avoid aggressive driving, such as sudden acceleration and hard braking. This can use up a lot of fuel and decrease gas mileage.

Regular maintenance, such as oil changes and air filter replacements, can also improve gas mileage. Make sure to follow the manufacturer's recommended maintenance schedule.
